Most builders start with tools and add design later. We started the other way round.
That difference runs through our whole design and build process: full visualisation before you commit, a fixed price before we start, and Kevin involved throughout.
From structural extensions to full renovations and fitted kitchens, every service starts with design and is delivered under one contract, one point of contact.
Why Homeowners Choose Us
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.
From the first conversation to the final handover, every project follows the same six-stage process. It is designed to remove uncertainty, keep you informed and make sure what you approve is always what gets built.
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.
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.
Our in-house team produces complete 2D plans and full 3D renders of your project. You see every room and every detail before anything is agreed.
Once the design is signed off, we produce a detailed fixed-price proposal covering every element of the build. The figure agreed at this stage does not change.
We coordinate every trade, every material and every stage of the build under one contract. Kevin is your single point of contact throughout.
On completion, we walk through every detail with you against the agreed design, room by room. Your project is handed back with a 12-month workmanship warranty.
How your project starts depends on where you are today. Either way, every design is fully visualised and agreed before we produce your fixed-price proposal.
We price from your existing plans and design your interiors as part of the project. No design fee is charged, and your design and specification are included as part of the full project scope, moving straight into a fixed-price proposal without any separate design stage or added cost.
We manage the full design process, from the initial brief through to complete 2D plans and 3D visualisation of the finished space. A design fee applies, which comes off your final bill if you proceed, and you own the design outright either way, whatever you decide once you have seen it. That is the deal, from the very first sketch.
PROJECT SCOPE
From a single new kitchen to a full home renovation, the same fixed-price process applies to every project we take on.
Single and two-storey extensions, rear and side extensions, wraparound builds and extensions built above existing structures across Berkshire.
Full property refurbishments, phased interior upgrades and modernisation programmes delivered under one contract.
Most Stevens Design & Build projects start from around £60,000, with the average project value around £150,000. Every proposal is priced individually to your project.
Design and build is not just a service category. It's a single design and build contract and the whole reason Stevens Design & Build exists: one company, personally led, doing every stage properly instead of passing you between different contractors, no gaps, no handoffs, no one to blame but us.
Whether your project is a single-room renovation or a full extension with a new kitchen, bathroom and bedroom included, the same standard applies. Every stage is designed, agreed and fixed in price before it begins, and Kevin remains your single point of contact from the first conversation to the day we hand back your keys, on every project we take on.
The reason for this is straightforward. The traditional model, appoint an architect, receive drawings, go to tender, appoint a builder, creates separate contracts with separate interests. When the drawings meet the reality of the site, the gap has to be absorbed somewhere. In a separated contract structure, that gap usually lands with the homeowner. By keeping design and construction under one contract, we remove the friction that causes delays, cost overruns, and disputes.
If you're not sure where your project fits, whether it's a single extension or a full renovation with kitchens, bathrooms and bedrooms combined, get in touch and we'll talk it through. There's no obligation, and no cost, for that first conversation. Book a free consultation whenever you're ready to start.
