Perspective sketch of the proposed extension

We have submitted a planning application for the approval of a ground floor extension to a property in Stoke Bishop. Careful consideration to the external appearance was required as the dwelling is located within a Conservation Area. This means the Local Planning Authority have created an appraisal highlighting the special characteristics and historical character of the area which generally need to be maintained in any new construction. This appraisal was used to inform our design choices and develop the proposal into something achievable.


Our design is very sympathetic to what is currently in place. We have continued the design language through the use of similar materials and expressing the structural elements and pattern that currently exists. The pattern of the exposed structural reinforced concrete beams that support the first floor set out the footprint of the extension. New timber beams are proposed to align with the existing reinforced concrete creating a softer and natural feel to the extension whichprojects into the garden.

A big part of this project was undertaking a sustainability assessment to understand the existing building fabric and building services. We produced a report detailing the features that are currently in place and how these can be upgraded to provide a more comfortable and energy efficient dwelling. The sustainability assessment begins its focus on the building fabric and details possible upgrade options i.e. this house has solid masonry walls with no insulation so we have proposed a number of routes to upgrade the walls each with varying costs, benefits, and feasability. You can read more on the sustainability assessment here.


We look forward to taking this project through planning and onto the technical design stage. We’ll continue to publish updates as they develop. You can read more about this project here, or explore all of our projects here.




We have recently been working on sketch proposals for a ground floor rear extension in Bishopston, Bristol. Following a series of design proposals and meetings with the client to narrow down the design and layout, we are now ready to submit the final proposal for planning.


The design seeks to reconfigure the entire ground floor by introducing a W.C. and a large utility room in the centre of the dwelling. A large kitchen/diner is located within the new extension with views over the garden. The lounge and a snug is positioned on the street facing side of the dwelling.

The height difference between the existing ground floor and the garden allowed us to develop a number of spaces through the use of a split level design. The kitchen/dining room is two steps down from the rest of the ground floor. A semi-sheltered landscaped patio, with seating and planting, is positioned adjacent to the extension and 3 steps up from the rest of the garden. The design developed by sharing sketches, plans, and elevations with the client. We also share a 3D model of the proposal which can be viewed from your own home on either a computer or tablet. The 3D model provides an immersive experience by allowing you to ‘walkthrough’ the design proposal to get a feel for what the end result could look like. Through online and in-person meetings, we were able to discuss feedback to progress the design to the next stage.


We look forward to taking this project through planning and onto the technical design stage. We’ll continue to publish updates as they develop.




Wellington Lane - an exemplar example of a sustainable dwelling we designed to passive house standards

As energy prices continue to rise, we are all thinking more carefully about how we consume energy in our homes. We often delay turning on the heating at home during autumn/winter which not only decreases our comfort levels but could also lead to issues such as increased condensation, black mould, and other problems that may affect the building fabric and create long term damage.


It can be difficult for homeowners to know what areas of the home are best upgraded and what the expected benefit, feasibility, and approximate cost could be. To help with this, we have been busy developing a sustainability assessment as part of our services which identifies areas of the home that could be improved to offer an enhanced level of comfort and energy efficiency.


During our site survey, we will produce a detailed report highlighting what is currently in place, and options for improvement and what the expected benefit, feasibility, and approximate cost could be. The report is broken down into two main key strategies:


Fabric First Approach

Designing to make dwellings much more comfortable and easier to heat in winter and cooler in summer, whilst providing a healthy indoor environment. Upgrading the building fabric such as walls, floors, roofs, windows, doors, etc. will minimise energy loss and maximise energy efficiency. Some of the topics in this insulation, airtightness, ventilation, passive design


Energy Focused Approach

Assessing the existing mechanical appliances within the home and looking to upgrade these appliances and/or implementing new strategies for heating, cooling, ventilation, etc. Some of the topics include heating, cooling, lighting, mechanical ventilation, water usage, and on-site energy generation.


A snippet from our sustainability assessment from a live project is shown below.

Fabric First - An understanding of the existing wall fabric will provide us with an idea of current heat loss and how best to go about making improvements to keep heat within the home for longer during the colder months.
Energy Focus - Understanding what appliances are currently in place will help us provide strategies for improving the heating strategy depending on the needs of the occupant

As shown in the examples above, we aim to offer multiple solutions which will vary in their cost and expected benefit. By providing a range of possible improvement options, we can discuss in detail with our clients which we think might be best for them and their home according to their budget and their needs.


This is a service we will offer as standard as part of our new renovation projects. We can also offer this service independently of any design work if required.


If you're thinking about building an extension or looking at a new build, get in touch to see how we can be of help. As architects, we aim to build in a sustainable manner exploring many options to suit our clients' needs.
