Indoor house plants can provide many psychological benefits to occupants, with the potential to improve mood, reduce stress levels, and increase productivity within work environments. Planting within pots has the benefit of keeping soil and water contained, whilst being portable if the plants need a change of environment, or your room needs a new look. Wet and humid areas, such as bathrooms and shower rooms, can provide environments for some plants to thrive in.

People of often unaware of the particulate matter (PM) within their homes produced by cooking, heating and fires, as well as the Volatile Organic Compounds (VOCs) emitted by chemicals in carpets, upholstery, paint, and cleaning products. Studies show that while plants can reduce VOCs within small sealed chambers, their ability to improve indoor air quality (IAQ) is limited, due to typical air exchange rates within buildings. Thus, good ventilation is the best way to improve IAQ.

Sick building syndrome exists and can be caused by a poor indoor environment and IAQ. We always design buildings with this in mind. Talk to us about how we can help improve your indoor environment.

Wood burning stoves are becoming more popular, providing both warmth and visual delight. They help satisfy our deep human connection with fire, right in the heart(h) of the home. Wood burning stoves can do wonders in an older property, or an older part of a property that has been extended. The thermal mass of masonry walls retains heat for slow release over longer periods, while heat from the fire can reduce humidity and prevent mould growth on cold surfaces.

On the other hand, burning solid fuels in our homes is impacting air quality and is the largest contributor to our national particulate matter (PM) emissions. The Government’s Clean Air Strategy aims to reduce PM by 30% by 2020 and 46% by 2030. Part of the strategy is the creation of smoke control areas (SCA) to restrict burning or provide exemptions on stoves and fuel. Your local authority will tell you if you’re in an SCA, while Oxford City Council has an interactive map.

Burning dry wood and chimney sweeping will help maintain your stove and reduce emissions. Talk to us if you are thinking about installing a wood burning stove as part of wider improvements to your home.

We are thrilled to be starting another new project in Oxford. Our client is looking to extend and refurbish their tired 1930s semi-detached house to provide open plan living spaces that flow better, with an improved visual and physical connection to the garden. The brief also includes a requirement for an additional shower room and dedicated laundry facilities, as well as a flexible space for a home office and guest bedroom.

When coming up with a design solution to this brief, it is important to consider the building’s orientation, where the light naturally enters the home, and where the existing drainage is located. This dictates that living quarters should be located to the rear to take advantage of openness to the garden and make use of the house’s full width. The ‘utilitarian’ functions are suited to the centre of the house, where natural light is less important, and drainage is within close proximity.

Flexibility is an important asset to have in the home. Talk to us about how we can assess the way you live to come up with creative ideas for how to improve your home.

For building regulations approval, which is better, a ‘building notice‘ or a ‘full plans‘ application? As architects, we would suggest that a ‘building notice’ is only used on smaller projects, where the work is of a simple nature and you have a competent and experienced contractor on board. Otherwise, we would always suggest a ‘full plans’ application, which consists of a detailed set of drawings that is fully coordinated with a structural engineer and any other required consultants.

This package of information is submitted to and approved by building control. Providing the construction work is carried out in line with the approved drawings, it will meet the regulations, which can avoid any nasty and potentially expensive surprises. On completion, a building control final certificate is issued, which is crucial when it comes to selling the property.

The building regulations are constantly changing, particularly Part L and F as building design changes in response to our climate emergency. We have a wealth of experience in this field. Talk to us about how to gain building control approval for your building project.

Permitted Development (PD) Rights – what constitutes PD for householders? There are different classes (A-H) that cover different types of work. We are often asked about extension work, which falls under Class A. The key things to consider are; area coverage of site curtilage; distance to boundary; height; eaves height; length; relation to the principal, side and rear elevations; materials; roof pitch. These considerations will differ depending on the house type and location.

Understanding if a proposal falls under PD can be quite complex. Reference should be made to the Government’s technical guidance. We would always recommend applying for a certificate of lawful development. This confirms if the proposal conforms with the PD guidance and thus if it is lawful. Having the certificate becomes particularly important when it comes to selling the property.

Restrictions can apply if your house is in a ‘designated area’, is listed or has had PD rights removed. If PD would not satisfy your brief requirements, then planning permission would be required. Talk to us about what would be the best planning route for your project.

The Government has a consultation setting out their plans for the Future Homes Standard and proposed changes to the Building Regulations. The aim is to increase the energy efficiency of new homes. However, the changes have fundamental flaws, and may even lead to homes that are less insulated than those built under the 2013 Building Regs. This is a step backwards during a time of climate emergency, when we should be aiming to deliver net zero carbon homes.

The proposed changes dissuade designers from adopting a ‘fabric first’ approach, by allowing the use of low carbon technologies (e.g. air source heat pumps) to pass a carbon target. This negates the need for a well-insulated building fabric. Using ‘carbon’ as a metric, as opposed to ‘at the meter energy’, results in inefficient homes that appear to be performing well. In addition, local authorities are to be stripped of their powers to go above and beyond the new Part L.

LETI (London Energy Transformation Initiative) have analysed the consultation and propose a direct response. Join us in becoming a signatory to the LETI Key Messaging by visiting: www.leti.london/part-l

“Housing fit for purpose” – we received this wonderful new book as a Christmas gift. It represents the way we should be doing things at the start of this new decade. Written by our friend and former tutor / supervisor Fionn Stevenson, the book provides a comprehensive review of how and why we should be evaluating building performance, crucially in relation to its occupants. It educates on housing design quality and the impact this can have on people and the environment.

Feedback through post-occupancy evaluation (POE) is essential – how else can we know how successful a building project was without receiving any feedback from the people that use it? This becomes increasingly important with the rise of low energy retrofit, where a pre and post retrofit POE can be carried out to gain a true picture of life before and after. It can bring up issues that may not have been considered at the design phase, which we can then learn from.

We understand the importance of feedback in building projects. Talk to us about how we can use our experience to help you deliver a successful new project or evaluate an existing one.

The Oxford School of Architecture at Oxford Brookes University now offers an alternative to the traditional qualification route to becoming an architect. The Architect Degree Apprenticeship allows those who have completed Part 1 (undergraduate degree) to carry out part-time study whilst working in practice, with intermittent ‘intensive’ workshops throughout the academic year. It is a refreshing alternative that we certainly would have considered during our education.

Last week, we were invited as visiting lecturers during the week-long ‘intensive’ to offer tutorials to students and feedback on presentations. Their projects were based within the Kings Cross masterplan in London, with some highly innovative ideas for sustainable design solutions. Some made use of the existing canal network with temporary / evolving ‘buildings’, while others looked at the upcycling of materials, often challenging the definition of architecture itself.

We enjoyed our role in educating the next generation and hope to become a future partner of the scheme. Talk to us about how our innovative design and research can inform your projects.

Another post about rooflights! And following on from our other rooflight post, we previously discussed the downside of condensation forming on the outside of triple-glazing, blocking out the views beyond. Well, on a frosty morning, the alternative can be a series of spectacular frosty patterns instead. On this occasion, the ice formed this inspiring leaf-like arrangement, in an organic and intricate way that nature seems to create so effortlessly.

For this to happen, the external surface of the glazing must be below 0 degrees. The internal surface of the glazing should be a maximum of 3 to 3.5 degrees below the indoor air temperature to maintain satisfactory thermal comfort, which it was in this case. Clearly, these rooflights are performing very well thermally, with minimal heat escaping to the outside. Meanwhile, it is the imperfections in or on the glass that allow the patterns to form in such a beautiful manner.

We understand building physics. Talk to us about how we can help you design your home or building in a way that maximises your thermal comfort within a beautiful and inspiring space.

Home of 2030. What will it be like? The desire is for a supply of new, long-lasting, green homes that are “healthy, safe and attractive places to live, that benefit people and communities”. This is exactly what Sow Space does, so we attended a workshop this week to give our two pennies worth. The workshop is one of a series run by the Design Council, an independent charity that advises the government on design, to help inform the brief for a design and delivery competition.

There was a great turnout, with people from a wide range of backgrounds, which was key to gaining a diverse and well-represented view on what makes a good home. Splitting into groups, we brainstormed and presented our views at the end. Our group effort focused on creating communities, with a strong connection to nature, whilst reducing consumption. Flexibility of working and new technologies were also identified as important considerations.

Are you thinking about how to improve or create a new home? We are already working on many homes and communities and would welcome the opportunity to speak to you about yours. Contact us here.

We were one of 350 attendees at the Architects Declare Event yesterday, held within the aptly named Grand Hall of the Grade II* Listed Battersea Arts Centre, wonderfully transformed as an ongoing project by architects Haworth Tompkins. The event kicked off with hugely inspiring and motivating talks by Jeremy Lent, author of “The Patterning Instinct”, followed by Oxford-based Kate Raworth, author of “Doughnut Economics”, which perfectly set the scene for the day.

We split into groups to discuss the 11 declaration points. Sow Space formed a group to discuss how to upgrade existing inefficient buildings, to put one of our areas of expertise to good use. The reflection that followed, along with a session where signatories voted for future action with their feet, brought about an abundance of positive energy to the room. We ended with the thought that it is courage we need, not hope, in facing the challenges of preventing climate catastrophe.

Visit the Architects Declare website to see the declaration we have signed up to. Talk to us about how we are striving to meet our commitments and you can help us too.

A big thanks to those who attended our talk last week on low energy retrofit! This came about following strong interest from local residents in understanding what they could do to their homes to combat our climate crisis. For context, the UK Government has declared a climate emergency and committed to net zero GHG emissions by 2050. The household sector alone represents 20% of total GHG emissions, while 80% of homes that will be standing in 2050 have already been built.

Clearly, we need a major upgrade of our existing housing stock, not only for energy and cost saving reasons, but thermal comfort too. Topics covered included the challenges and cost of retrofit, Passivhaus / Enerphit as a benchmark, the importance of POE. A long discussion followed, where one conclusion highlighted that if you only have a small sum of money to spend on retrofit, work out what the most problematic areas are and address these first to maximise enjoyment of your home.

Contact us if you’re considering a retrofit project alongside more major changes to your home. Otherwise, you can talk to Cosy Homes Oxfordshire, or find more info at GreenSpec and Energy Saving Trust.

Trees play a critical role in tackling catastrophic climate change. According to Friends of the Earth, just 13% of the UK’s total land area has tree cover compared to an EU average of 35%, while Oxfordshire stands at only 9%. There is a campaign and petition to double Oxfordshire’s tree cover by 2045, which we have signed here. We will also be helping to plant 300 trees at the Croft Road recreation ground on Saturday 23 November, marking the start of National Tree Week.

One of the main challenges in ‘greening’ our cities with trees and plants is the amount of traditional hard surfacing in the form of buildings, roads, pavements etc. As well as removing our emissions, plants create ‘green corridors’, which helps wildlife to navigate our built environment, while growing edibles helps to reduce the ecological footprint of occupants. With some innovative thinking and design, buildings can be part of the solution by harbouring plant life within the building fabric.

Talk to us about how we can incorporate plant life on your building projects to make our built environment part of the solution to our climate crisis.

A quick concept sketch for one of our current new-build house projects shows a connection to the main driving force behind the scheme – a spectacular view of a lush green meadow. Deer are often found jumping playfully through the meadow, and with the deciduous trees in the distance with the sky and clouds above, this view creates an ever-changing landscape for the occupants to enjoy and feel inspired by all day and all year round.

Our primary focus was to capture and frame this view upon entering the property. A double-height entrance hall space, with glazed gable and minimal visual obstructions aims to achieve this. The entrance hall forms a spine down the centre of the house, splitting the living and ancillary quarters. A viewing platform / bridge at first floor level makes something as routine as moving between rooms, a completely joyful experience.

Get in touch with us if you have a project in mind and we can help you get the best out of your site, whether that’s starting from scratch, or adapting and improving what you already have.

We attended an ARTE documentary viewing last week titled ‘Rewilding Europe’. It was held within the spectacular Victorian neo-Gothic setting of the Oxford University Museum of Natural History, designed by Benjamin Woodward, of the Irish practice Deane and Woodward. The documentary discussed lessons learnt from the re-introduction of wolves to the Yellowstone National Park in the US, with the aim to control the rising elk population. The introduction of one species had a profound effect on an entire ecosystem.

Another interesting topic was how to define ‘wild’? One definition was: ‘the ability to be entirely self-sufficient’, or in other words, ‘sustainable’. We drew many parallels from this with the architectural world, where all aspects of design must be considered to arrive at a solution that is best for the whole. Like ‘wild animals’, how can buildings utilise the ecosystem they exist within to become sustainable? Which resources can be harnessed to help buildings become net zero carbon?

Talk to us about how we consider the holistic ecological impact and sustainability of a building project.

The humble rooflight. A means to introduce natural daylight and ventilation into a space. A view out to the bold blue sky, the tops of trees, ordinarily out of sight. There are many things to consider when specifying a rooflight. We installed six of them on our Croft Road project, making those spaces much brighter than other rooms in the house, due to the increased exposure to the sky. This has helped to reduce reliance on artificial lighting, whilst creating new views into the distance that never before existed.

Internal black-out blinds in the loft help the occupants get a good night’s rest, while external shutters to the south block out the hot summer sun. Triple glazed units provide superior thermal performance, although one downside is the condensation that forms on the outside, blocking some of those spectacular views. Another thing they help to block out, often not considered when specifying, is the passage of sound. This is especially apparent on a roof that receives a lot of rain!

Take a look at our projects and let us know if we can help you to maximise natural light or create new views within your home.

We are incredibly excited about our new project start in Oxford – the extension and low energy retrofit of a 1930s semi-detached house. Our client has the highly admirable aspiration to achieve the Passivhaus standard, or Enerphit for retrofit projects, which would reduce existing energy use by 90% through the use of super insulation, an airtight building fabric, minimal thermal bridging and a mechanical ventilation system with heat recovery (MVHR). In our client’s words:

“Everyone needs to massively reduce energy demands to have any hope of curbing climate disaster. Passivhaus / Enerphit needs to be promoted – it makes so much sense for families, and the community, and could make a serious reduction to national energy demand if widely used.”

This typical semi makes up a large proportion of the existing housing stock, following the 1930s and inter-war housing acts that were responsible for their existence. This project has the potential to be considered as a positive model for others to follow.

Taking on one of our ‘Architects Declare’ responsibilities to help educate the next generation of architects about our climate emergency and what we can do to address it, we gave a lecture this week at Oxford Brookes University, to year 2 architecture students about low energy retrofit. The lecture was held in the Sir Kenneth Wheare Hall, an excellent multi-functional space, within the newly refurbished Clerici building by Berman Guedes Stretton Architects. The space was a joy to use and a vast improvement in teaching and learning facilities since our days studying there!

One aim of the course module is to bridge the gap between academia and industry. Our lecture explained what low energy retrofit is and why it’s so important, we discussed energy standards including Passivhaus / Enerphit, we presented one of our live retrofit projects with the challenges involved, and finally we talked about post-occupancy evaluation (POE) and how crucial it is to learn from what we’ve done in order to improve. The students were highly engaged, asking intelligent questions on the subject. We look forward to the next time.

“The twin crises of climate breakdown and biodiversity loss are the most serious issues of our time. Buildings and construction play a major part, accounting for nearly 40% of energy-related carbon dioxide (CO2) emissions whilst also having a significant impact on our natural habitats.

For everyone working in the construction industry, meeting the needs of our society without breaching the earth’s ecological boundaries will demand a paradigm shift in our behaviour. Together with our clients, we will need to commission and design buildings, cities and infrastructures as indivisible components of a larger, constantly regenerating and self-sustaining system.”

We are proud to be a signatory to the open letter declaring a climate and biodiversity emergency, making a commitment to positive action in response. To see the full letter and to sign up, go to:

We often pass this gem when exploring the delightful Welsh village and lily ponds of Bosherston in South Pembrokeshire. Named ‘Styll’ or ‘Style’, this well-preserved Grade II listed building was an 18th Century farmhouse that boasts a fully slate-tiled front façade and roof. The small slates were most likely sourced locally, given the historical prominence of Pembrokeshire and Welsh Ordovician slate. Each one is unique, creating a completely uneven, rustic pattern that puts it at odds with the smooth and regular modern-day tiled surfaces. We love its distinctiveness and its ability to generate an ever-changing texture of light and shadow, according to the time of day. This intricate tapestry would have taken great skill and care to complete. Its hand-crafted aesthetic truly reflects the personality of those who installed it.

We attended an engaging workshop yesterday about the role of innovation for social enterprises, run by local business network Oxfordshire Greentech. It was held at the Old Fire Station / Corn Exchange, based in the gothic red-brick buildings on George Street, designed by prolific Oxford architect Harry Wilkinson Moore. Arts at the Old Fire Station are doing great things for the arts, creativity and above all inclusivity and breaking down social barriers. They have created an excellent venue and an invaluable resource for the public.

During the workshop, we engaged in some fascinating discussions, covering such topics as; defining sustainability, the Social Value Act, the Buy Social campaign, Earth Overshoot Day, eco-tourism. Speakers and attendees included some of Oxfordshire’s most inspirational individuals and organisations, who shared with us some like-minded motives and values, with lots of potential for collaboration. We discussed how to promote ourselves as innovative market leaders, putting a strong emphasis on value over cost. It made us feel incredibly proud and positive that change is happening, and right on our door step.

We attended a series of short talks last week about wildlife conservation at the beautiful Bernard Sunley Lecture Theatre, St Catherine’s College, designed by Danish architect Arne Jacobsen. The species discussed included the Sehuencas water frog, in the form of Romeo the world’s loneliest frog, as well as the rediscovered Togo slippery frog, both of which featured as successful survivors of extinction. Clearly, big change is required to help our planet’s wildlife to survive human-made climate change, and big change is required to do our part in striving for a low carbon and low impact society. Our main takeaway from the talks was that, in order to incite change, a captivating story or narrative really helps to engage people.
