Design & Build
One team, one contract and one fixed price, covering every stage of your project from first sketch to final handover.
THE FULL SERVICE
The traditional route means appointing an architect for the drawings, going to tender, then appointing a builder. Separate contracts, separate interests, and when the drawings meet the reality of the site, the difference lands with you. Design and build puts everything under one contract, with Kevin overseeing every drawing, every material and every trade himself. One expert holding the whole project to a single standard is what produces the home you were shown at the start, rather than a compromise negotiated between three companies.
Where your project starts depends on where you are today. Either way, everything is fully visualised and agreed with you before we produce your proposal.
We work from your existing drawings, so you are not paying twice for work already done. Kevin reviews what you have and brings his full experience to it, designs the interiors and specification around it, and moves you towards a proposal sooner than a project starting from scratch.
Kevin starts from a conversation about how you want to live in the space, discusses your vision and what you want the finished home to feel like, then our team produces full 2D plans and 3D renders. You approve every room on screen before anything is costed or committed.
WHAT IS INCLUDED
PROJECT SCOPE
From a single-storey extension to a whole house rethought, the same design work, the same craftsmen and the same standard applies to every project we take on.
Single and two-storey, rear, side and wraparound, and extensions built above existing structures.
Whole-property refurbishments, phased interior upgrades and modernisation programmes under one contract.
Knock-throughs, load-bearing removals and full reconfigurations, designed and certified by independent Chartered Structural Engineers.
HOW IT WORKS
Every service follows the same six stages: a free design consultation, survey and feasibility, full 2D and 3D design, one fixed proposal, the build, then handover with a 12-month workmanship warranty. Nothing starts until you have seen it and said yes.
FREQUENTLY ASKED QUESTIONS
With an architect you appoint one company for the drawings, go to tender, then appoint a builder, with separate contracts and separate interests. When the drawings meet the reality of the site, the difference lands with you. Design and build keeps both under one contract, so the responsibility sits in one place.
Yes. Kevin works from your existing drawings and designs the interiors and specification around them, which brings you to a proposal sooner. We still offer our expertise and advice on your existing designs.
Yes. The design stage is a properly resourced piece of work, takes considerable time and expertise, and it is priced accordingly as part of your project. Kevin explains exactly what it covers and what it costs at the free consultation, before you commit to anything.
Yes, both are managed as part of the project. Structural work is designed and certified by independent Chartered Structural Engineers.

Yes. You can appoint us for construction alone or for the full service covering design, supply and installation of every element.
Design and feasibility typically run over a few weeks, and the build depends on scope. You receive an indicative programme with your fixed proposal.

Given the task of producing smart units at the end of a living area, but future proofing for a kitchen should the room change its use, Kevin guided us through all the options with infinite patience. The result is most pleasing, matching the walls to perfection and a pleasure to look at and use. The fitters came on time, left on time and were skilled and careful – all supervised by Kevin who is very hands on. Rare these days. We could not be happier.

We have worked with Kevin a number of times on different projects over the past 10 years and have always found him to be reliable, professional and great fun to work with. Kevin has a great eye for design and is an excellent project manager who makes the whole process painless. His advice through every stage was invaluable, from planning the design right through to the finishing touches. Nothing is too much trouble and any problems are addressed immediately. He always goes above and beyond and the end result of our latest project together is even better than we could have imagined! We are absolutely delighted with everything and would not hesitate to recommend him to others.

We have seen most of Kevin’s work over the last few years and can honestly say the design and finish of his kitchens and builds are outstanding. We can thoroughtly recommend Stevens Design & Build, both Kevin on a personal level, and the company on a professional level. If you have any doubts just go for it.

We engaged Kevin to design our kitchen five years ago as we wanted to swap two entire rooms, moving the kitchen to another location, which we knew would be beyond most designers as they are usually kitchens only. As an all round designer and project manager, we knew that Kevin would also be able to design a complementary room where the old kitchen was, taking the theme through into the second space. We liked the results so much that we’ve just had him back to design two bedrooms for our daughters, which they love.

Many thanks to you and your team for all your hard work and making our small project reality, with the minimum of disturbance to ourselves. We couldn’t have asked for better organisation and site cleanliness and that’s all down to you Kevin, absolutely outstanding. As for the final result : Superb. Highly recommend. Many Thanks. Ave and Sandra.

I couldn’t be more pleased with the work Stevens Design & Build did on our recent project. They managed every aspect of the build, from the construction itself to the flawless installation of the kitchen, utility, and pantry. The entire project was completed right on schedule and within the budget we set, which is a rare find in this industry. Not only did they meet my expectations, but they truly exceeded them with their attention to detail and quality craftsmanship. I was so impressed that I’ve already recommended them to one of my friends who’s planning a similar project. If you’re looking for a team that delivers outstanding results, look no further than Stevens Design & Build!
