Google Reviews
Based in Brentwood, Essex, we were also introduced to builders and tradespeople through Kirkwood, and they were excellent—professional, respectful, and a pleasure to work with. If we ever take on another project, we wouldn’t hesitate to use them again.
We now have an amazing extension, and would be happy to use the team again.
Very knowledgeable and contactable throughout the process.
Couldn't ask for a better outcome and value for money.
Will definitely be recommending and 100% will use again!

Our architectural design services in Coggeshall
Kirkwood are experienced Coggeshall architects offering complete architectural design services for homeowners planning to extend or improve their property. From early design ideas to structural calculations and planning permission in Coggeshall, our house extension planning package covers every step.
Architectural plans & drawings
We produce clear and detailed architectural plans designed to suit your house extension budget. Some projects require full building regulations drawings for construction, while others only need planning drawings for approval. All our extension plans are drawn to scale, easy to understand, and professionally presented. Every set of plans is prepared to meet the requirements of Braintree District Council
Planning permission & permitted development
We will advise you on exactly what type of application your house extension needs. It could be full planning permission, a householder application, permitted development, or prior approval. In Coggeshall, permitted development is often a common route, but it still needs council approval and a Certificate of Lawfulness. We handle all the paperwork and deal directly with Braintree District Council on your behalf.
Building regulations & structural calculations
All house extensions must meet building regulations. We prepare a full set of technical drawings and include structural calculations if needed. These extension plans are used for council checks, builder quotes, and the construction itself. Building regulations drawings can also be provided if your project requires them, although they are not always necessary.
Extension planning in Coggeshall
We offer a complete extension planning service in Coggeshall, covering everything you need for your house extension. It starts with a quick Zoom call where we explore what is possible and give you honest advice on design ideas and build cost estimates. Think of us as your own house extension affordability guide, and the planning advice is completely free.
How much does an architect cost for a house extension in Coggeshall?
Architect costs for house extensions in Coggeshall usually start at around £1,400 and can rise to £3,000 depending on the size and complexity of the project. A smaller single storey extension under permitted development typically falls between £1,400 and £1,700. Detached homes may be slightly more due to the extra time required for accurate site measurements. Although the cost of architectural plans is small compared to the full build, it is one of the most important stages. If the design is wrong at the start, the entire project can go off track. We have been brought in to fix enough of them. Choose an experienced Coggeshall architect and start your project the right way.
Architect costs for house extensions
Architectural design costs vary depending on the size and type of your property. Larger homes take more time to survey and require more detailed drawings, which can increase the overall price. Double storey extensions are often the most expensive, while garage conversions are usually the most cost-effective. If your extension includes internal layout changes, this can also add to the cost due to the extra design time involved. As experienced architects in Coggeshall, we create clear and accurate house extension plans based on your layout, needs, and budget.
What’s included in our architectural design services
Our architectural design services for Coggeshall house extensions include everything you need to get started with confidence. We begin with a full measured survey of your home, inside and out. From there, we produce detailed existing and proposed extension plans, along with any required amendments. You will also receive a design revision consultation to refine your ideas, followed by full planning application submission and ongoing management with Braintree District Council.
It don’t stop there
As experienced Coggeshall and Essex architects, we deal directly with the council on your behalf so you do not have to worry about the paperwork or process. We also provide a free build cost estimate at the beginning and can introduce you to trusted local builders with fair pricing. From single storey extensions and garage conversions to full double storey projects, every part of our service is shaped around your needs and delivered to a high standard.

Can I convert my garage in Coggeshall?
