We have worked with Carl and Kennet Design on a number of projects now and we can fully recommend their services. Kennet produce some fantastic designs and show a keen eye for detail as well as demonstrating creative solutions to day to day problems.

Communication and project management is always very clear and slick throughout the entire process making it easy for both us as garden designers and for the client. It is always a pleasure to work with Carl and his team. Aubrey.

Andy Sonden

Whilst it’s fair to say that we kissed a lot of frogs in our search, it was worth it to find Kennet Design.

Carl and his team did an amazing job right from the very first phone call, working with my wife and I to establish a design concept, providing advice and insight on how the ideas we had could be realised in a practical home, and guiding us through the minefield that is planning regulations. 

James Marshall

“Kennet Design did everything to get our house renovations ready to build (side return extension and loft conversion).

This was from the initial survey of our property, consultation on our wants and likes to help input into the design, detailed designs, structural drawings, planning applications and all those little things you are not aware of.”

Naeem Atta
Kennet Design spent a significant amount of time with me till it was all clear. During the process we also changed our mind several times about what we wanted. Kennet were very supportive and understanding and made several changes to the plans happily. Throughout my two planning applications, all my queries were answered. Overall I am very satisfied with their prompt and professional service and would strongly recommend Kennet Design to anyone wishing to take their services.

The project was complicated by the need to adjust plans over a period of time in order to ensure listed building consent. The nature and condition of the old house required additional input from structural and historic experts – and Carl was able to recommend thoughtful professionals who could explain their findings to us in layman’s terms. Realising the finished design required a skilled and versatile local builder, able to work in traditional and modern materials – once again, Carl’s recommendation proved to be vital and we are delighted with the result.

Tracy Beare

Just had to say a huge thank you to Carl for getting our planning permission through. We have a small grade 2 listed cottage and wanted to correct some of the work that had previously been done to it and also put a loo and basin upstairs!!!! From the very first phone call we had, he was so helpful, friendly and knowledgable.

He knows his stuff. When we are ready to go ahead with the next stage of our project, I will be on the phone Carl (sorry you can’t get rid of us).

About Us
Architectural practice in Newbury, Berkshire

Proactively managing your architectural project from start to finish

Our project manager Richard will carry out a 60-minute full measured survey, using laser tools and digital mapping to capture every detail. These measurements form the foundation for your drawings — accurate, reliable, and ready for planning and structural design.

Our architect will create a full set of proposed drawings, showing layouts, elevations and materials. These aren’t just pretty pictures — they’re practical, buildable plans. We’ll walk you through the designs, take on board your feedback, and refine everything before submitting for planning.

Before anything is submitted to a planning authority or priced by a builder, we can show you exactly what your finished project will look like. Our photorealistic 3D visualisations let you see your design in its setting — the materials, the light, the view from the garden — so you can make decisions with confidence and arrive at planning with a proposal that’s already been properly considered.
 

Our structural engineer steps in here, producing calculations and load-bearing designs that match your plans. Whether it’s steels for an open-plan layout or reinforcements for a new storey, this is where we make sure it all works safely — and affordably — in the real world.

Once planning is in place, we prepare the detailed construction drawings for building controls approval. We can work with either your local council or a private inspector. This stage ensures everything complies with regs — structure, fire safety, drainage, insulation — so you’re legally covered and ready to build.

99% of the planning applications we submit are approved first time. That’s not a figure we arrived at by avoiding difficult projects — we work regularly with listed buildings, conservation areas, AONB sites and Green Belt plots across Berkshire, Oxfordshire and Wiltshire. It comes from doing the right work before an application is submitted: pre-application consultation, thorough heritage assessments where needed, and designs that engage seriously with local planning policy rather than hoping for the best.

We pull together a detailed cost breakdown, timeline and work schedule. You’ll know exactly who’s doing what and when, with no last-minute surprises. Health & safety compliance is managed throughout, and we stay hands-on from day one to final handover. It’s a managed build — not just a collection of trades.

A message from founder and director, Carl Drury

Over the years, I’ve been called in at every stage of a project; sometimes at the beginning, often after something has gone wrong. A planning refusal that “no one expected.” A builder relationship that has turned sour. A budget that drifted so gradually the owners only realised when it was too late.

One client told me, “We thought we were saving money.” By the end of the build, she had spent more correcting early decisions than she would have spent appointing the right team from the outset. Nothing dramatic, just small gaps in judgement that compounded.

That is what shaped how I practice. Architecture, in my view, is not about chasing trends or producing images for brochures. It is about protecting value; financial value, architectural integrity, and the long-term satisfaction of living in a well-resolved space. Much of that work happens before construction begins: reading planning policy carefully, identifying risk early, insisting on clarity in drawings, and structuring contracts so the client is protected when pressure inevitably arises.

The cheapest decision at the start is often the most expensive at the end. We avoid shortcuts, control detail, and protect value, so your build costs dont spiral and your investment holds its integrity over time.

We're an architectural practice based in Berkshire, serving Oxfordshire, Wiltshire, Hampshire and beyond

As an architectural practice in Newbury, Berkshire and Oxfordshire, we work mostly across the South of England from Berkshire and Oxfordshire to Wiltshire, Devon and Cornwall, we have guided hundreds of clients through the process of reshaping their homes. Every county has its own character: the market towns of Oxfordshire, the stone cottages of Wiltshire, the coastal homes of Devon and Cornwall. Our work respects these settings while re-imagining them for modern life.

Sometimes it’s a growing family needing space in Berkshire. Sometimes it’s a farmhouse in Wiltshire that deserves careful restoration. Sometimes it’s a coastal property in Cornwall, where the challenge is balancing sweeping views with resilience against the elements. In each case, our approach is the same: clear guidance, elegant solutions, and designs built to last.

Andy Sonden

Whilst it’s fair to say that we kissed a lot of frogs in our search, it was worth it to find Kennet Design. Carl and his team did an amazing job right from the very first phone call, working with my wife and I to establish a design concept, providing advice and insight on how the ideas we had could be realised in a practical home, and guiding us through the minefield that is planning regulations. 

Kennet provided the designs for the interior and exterior, working to revise the plans based on our ideas and comments and gently but firmly pushing back when we suggested things that were either impractical or impossible. Recognising that we were working to a budget, Carl also identified areas of the build where we could reduce cost, whilst still delivering a finished result that looks a million dollars. Even with the restrictions placed on our concept by planning regulations, Kennet helped us to push the envelope to deliver more than we thought would be possible, including negotiating some pretty tricky feedback from the planning officer.

James Marshall

Kennet Design did everything to get our house renervations ready to build (side return extension and loft conversion). This was from the initial survey of our property, consultation on our wants and likes to help input into the design, detailed designs, structural drawings, planning applications and all those little things you are not aware of.

All this was complete with a friendly and professional stance. I can not recommend them highly enough they walked us through the whole process, gave advice, and put up with our changes as the project developed.

They kept us informed throughout the process and Carl is always on hand to answer any questions. When appointing builders all commented how comprehensive the design and detail was meaning we could get accurate quotes. Been a smooth and happy process and looking forward to finishing the build.

Naeem Atta
I undertook an extensive extension on my family home and was quite apprehensive about how to go about doing this.
 
I contacted Kennet Design who came to the property and clearly explained the complete process to me from planning to structural calculations to the process of application.
 
They spent a significant amount of time with me till it was all clear. During the process we also changed our mind several times about what we wanted. Kennet Design were very supportive and understanding and made several changes to the plans hapily. Throughout the two planning applications, all my queries were answered promptly and overall I am very satisfied with their prompt and professional service and would strongly recommend Kennet Design to anyone wishing to take their services.

Ours was a long project from initial design ideas to actual completion. We wanted to renovate and extend a listed building. From the outset, Carl, of Kennet Design, sought to understand our views and ideas, while helping us understand what might be possible and realistic.

The project was complicated by the need to adjust plans over a period of time in order to ensure listed building consent. The nature and condition of the old house required additional input from structural and historic experts – and Carl was able to recommend thoughtful professionals who could explain their findings to us in layman’s terms.

Carl was able to meet them and us on site as required. Realising the finished design required a skilled and versatile local builder, able to work in traditional and modern materials – once again, Carl’s recommendation proved to be vital and we are delighted with the result.
