We’ve worked with residential architects before, but Jamie and his team, especially Nathan, were fantastic. Kirkwood designed plans for our double-story side extension, loft conversion, and single-story rear kitchen extension, and we knew we had to choose the right company since it involved our entire home.

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.

Kirkwood done a fantastic job on our architectural plans for our new single story kitchen extension in Brentwood. They gained us approval from the council and also provided the structural engineering for the project. We used their recommended builder who so far, we cannot fault one bit. Thanks again and highly recommend.

The Kirkwood team were a pleasure to work with and have in our house. What can be a stressful time was made a lot easier by a team who build with quality, communicate clearly, and address and action any questions you raise....however small or large.
We now have an amazing extension, and would be happy to use the team again.

Kirkwood Design and Build Builders, Wickford did a fantastic job on our extension in Billericay. They helped with planning permission, design, and build. Professional company through and through. Given that we haven't done such a large project before, we were a bit nervous and had a lot of questions. Jamie and his team from Kirkwood Design and Build Builders was good putting us at ease and now that we are fully complete with all our work, we further appreciate how professional this company is. Would highly recommend.

Our work
Request design costs

Why choose our architectural design services?

Our core company value is honesty. Thats why we provide you with expected home extension build costs upfront. We know this may deter some customers as often, they are unaware of how much things cost. We don’t look at that as a failure, we look at that as a success. Our first job is to help, and if a job comes from that, then it’s a bonus. 

Decades of industry experience

Our teams combined experience technically makes us ancient. We should be in a museum, not providing a home architectural design service in Essex. This is good news for you because it means we've already made every mistake under the sun. We see ourselves now as a company setting the standards for other companies to follow. Through honesty and transparency, we lead the way.

Customised Solutions for Every Home

No two jobs are the same, in fact they're much like fingerprints. Our first job is to listen to the customers needs and seen what is possible with the property we can advise on the type of house extension that would best suit and most likely be approved by the local authorities.

Comprehensive Design to Build Support

  Once we have the design done, submitted and to your satisfaction, we don't stop there. We like to know our architectural design service customers move into safe hands so we have a few reliable builders we can pass you to. We can support you with all the questions in the world, just pick up the phone and drop us a call.

Our Architectural Design Process

In our eyes, there is only one way to do each job and that’s the right way. We treat projects as if they were our own. If we can think of ways to save you money and hassle we will advise and try to steer you in the direction that will get you to where you’ve told us you need to be. An architectural design service can be a fun and exciting experience. 

Initial Consultation and Site Visit

If you have received a quote from us already you'll know how competitive we are. To save on costs we can provide you 90% of the answers before making a site visit. We do this by researching your property and viewing it on google earth. We can see what neighbouring properties have had done which gives us good insight into planning oportuities.

Whether you want a simple single storey rear extension, a complex double storey with internal reconfigurations, or a complete house renovation with new room layouts, Kirkwood draws the plans from scratch, tailored to your home. No off-the-shelf house plans — every drawing is specific to your property.

Concept Development and Drafting

Once you've gave us the green light, we start the survey. This is where we measure every nook and cranny so we can first draw the existing. Once that's done we can then start playing with some design ideas for the proposed work. We won't stop designing until we have something you love. This is usually achieved in the first draft or sometimes the second.

Planning Permission and Regulations

With regulations constantly changing in Essex, its worth working with a company that has its ear to the ground. We make sure every project complies and always gain some form of approval from the council just to make sure. Although not always required, we can offer building regulation drawings. If you're not willing to risk leaving it to your builder how to construct your home extension, let us do it for you. An architectural design service should not just end there. We can help with structural calculations too.

We live in a busy world but if you do get time, all we ask is for a honest feedback.
