About Stevens Design & Build

A Family Name, Returned To With Confidence And Built On Design From Day One

Stevens Design & Build is a family-run design and build company led by Kevin Stevens. Unlike most builders, we started with design, not tools, and grew from there into a full-service build company delivering extensions, renovations and kitchens across Berkshire, Buckinghamshire, Surrey and Oxfordshire.

Why We Are Different

Most Builders Add Design. We Started With It.

DESIGN LEADS. THE BUILD FOLLOWS.

Our Services

From structural extensions to full renovations and fitted kitchens, every service starts with design and is delivered under one contract, one point of contact.

Design & Build

One team, one contract and one fixed price, covering every stage of your project from first sketch to final handover.

Home Extensions

See exactly what your extension will look like before we break ground, then watch it take shape for one fixed price, start to finish.

Home Renovations

Every room, rethought and fully visualised before we start, delivered under one fixed-price contract with Kevin involved from beginning to end.

Kitchen Design

From layout and cabinetry to worktops, appliances and lighting, every kitchen starts with a full 3D visualisation before a single unit is ordered.

Bathroom Design

From layout and tiling to fixtures, lighting and finishes, every bathroom starts with a full 3D visualisation before a single tile is ordered.

Bedroom Design

From layout and storage to finishes and lighting, every bedroom starts with a full design before a single unit is fitted.

Outdoor Kitchens

Permanently built and fully equipped, every outdoor kitchen is designed to handle the UK climate, not just look good for one summer.

Why Homeowners Choose Us

Trusted by Homeowners
Across the Home Counties

Every project we take on carries Kevin's name and years of reputation behind it. Homeowners choose us because we make the process honest, transparent and personally accountable from start to finish.

Design-Led From Day One
Most builders come off the tools and start a building company. We started with design, which means every project begins with a properly considered plan, not a quick sketch on the back of an envelope.
One Contract, One Point of Contact
Every trade, every material and every stage of your project is managed under a single contract. Kevin is your point of contact throughout, not a rotating cast of site managers.
One Fixed Price Before We Start
We agree a detailed fixed-price proposal before any work begins, and that figure does not change. No ballpark estimates, no surprises during the build, no unexpected bills on handover day.
Full 2D and 3D Visualisation
You see complete plans and 3D renders of every room or space before anything is agreed, so what you approve on screen is exactly what gets built in your home, with no interpretation left to chance.
FMB Accredited
Stevens Design & Build is a Federation of Master Builders accredited firm, independently assessed on quality, reliability and trading practices, giving you an extra layer of confidence in who you are hiring.
12-Month Workmanship Warranty
Every project we complete carries a 12-month workmanship warranty. That is how confident we are in the standard of work you will find behind every door we finish, on every project we take on.

MEET KEVIN STEVENS

That’s what makes us different: not a franchise, not a call centre, just Kevin, personally involved in every build, start to finish, across Berkshire, Buckinghamshire, Surrey and Oxfordshire.

We visit your home, listen to your brief and give you an honest view of what is achievable. There is no obligation and no sales pitch, just a straightforward conversation about your project and what it could look like.

Feasibility

We assess layout possibilities, planning requirements and structural considerations for your project. Ideas become a clear, properly costed plan, giving you a solid, realistic foundation before any design work begins.

Graham Nicholls

I have collaborated with Kevin on projects in the past and always admire his high standard of work, professionalism, and passion for doing a great job. I would highly recommend him and his company!

DAVID HARROLD

January 15, 2025

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.

Steven Yeoman

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.

I’ve worked with Kevin in a few projects over the years. He has a great design eye, is very detail oriented, has a great team and is a lovely guy! I highly recommend!

Sandra Hawes

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!
