Design & Build Services in London

Most renovation problems start in the gap between the architect and the builder: drawings that can’t be built for the budget, details nobody owns, and a homeowner stuck in the middle. Our design and build service closes that gap. We design, engineer and build your project under one contract, with one team responsible from the first sketch to the final handover.

Since 2015 we’ve delivered over 180 projects across London, from extensions and loft conversions to full renovations, listed buildings and new homes. Design is handled in-house by S & M Design Ltd, so everything we draw is practical, buildable and priced before work starts on site.

At S&M Solutions, we believe that every project is unique, and we approach each one with a fresh perspective. Our innovative methods ensure that your property is designed and built to the highest standards, reflecting your vision and requirements.

One contract, one team.

You deal with one company for design, planning, structural engineering, Building Regs and construction. Nobody passes problems between consultants and contractors.

Designed with the build in mind.

 

Our designers work alongside the people who build, so every scheme is buildable and priced realistically from the start.

Clear costs before work starts.

Your estimate is based on a defined scope and detailed drawings. Everything included is listed, and anything that can’t be priced until work starts is flagged up front.

Fully managed, start to finish

Every project is managed by an experienced construction professional with over 22 years in the industry, with fortnightly site meetings and live updates through our client portal. You always know where things stand and who’s responsible.

How our design and build service works

1.

Enquiry and site visit

Tell us about your project, property and budget. We review every enquiry personally and, if it’s a good fit, visit the property to talk through what you want to achieve and what the site allows.

2.

Design and approvals

Our in-house team designs the scheme, handles planning or permitted development, and prepares the structural and Building Regulations drawings.

3.

Detailed estimate

With the drawings in place, we prepare a detailed written estimate and go through it with you in person, line by line, so you know exactly what’s included.

4.

Build and handover

Once the contract is signed, we programme the works and start on site. You get fortnightly site meetings and live updates through our client portal. At the end, we walk through the finished work with you and stay on hand after handover.

Design and Build FAQs

What is design and build?
One company designs, engineers and builds your project under one contract. You don’t have to manage an architect and a builder separately, and there’s one team responsible from the first sketch to handover.

Do you handle planning and Building Regulations?
Yes. Our in-house team prepares the planning or permitted development application, the structural design and the Building Regulations drawings, and deals with the council and building control for you.

Is design and build more expensive?
Not necessarily. Because the scheme is designed with the build and budget in mind from the start, your estimate is based on detailed drawings and a defined scope, and anything that can’t be priced yet is flagged up front.

Can you work from my existing drawings?
Yes, we can price from them. The service works best, though, when we’re involved from the start.

Do you work on listed buildings and in conservation areas?
Yes. We’ve completed a Grade II listed refurbishment in East London and work regularly in the Greenwich and Blackheath conservation areas.

Which areas do you cover?
We’re based in Blackheath and work across South East, Central and East London.
