Design and Build Contractors in Greenwich

Extensions, loft conversions, renovations and heritage refurbishments across Greenwich and SE10.

There are a lot of moving pieces in a building project in Greenwich: architects, structural engineers, planning applications, builders, decorators — all needing to work together in the right order, at the right time, without the whole thing unravelling.

When they do not line up, you are left chasing calls, managing delays and trying to hold the budget together. That is rarely where a homeowner wants to be.

At S & M Solutions, we manage your Greenwich project under one roof — design, planning, structural work, build and finish. One team. One point of contact. One clear plan from start to finish.

Reliable Design and Build Company in Greenwich

Our service covers the full process — from initial design and planning through to construction and completion. Every stage is managed with a clear focus on buildability, cost control and quality of finish. No stage is handed off without accountability.

Whether you are planning a house extension, loft conversion, full renovation or heritage refurbishment in Greenwich, we bring the same integrated approach to every project. You deal with us. We deal with everything else.

Experienced Design and Build Contractors in Greenwich

With over 180 projects completed across South East and Central London, and more than 22 years in construction, we have built a reputation on delivering what we say we will deliver. We are FMB members, TrustMark accredited and led by NVQ Level 6 construction site management experience.

Our approach is built on coordination. By managing both design and construction, we reduce risk, improve decision-making and maintain consistency throughout the project. The result is a finished build that reflects both the design intent and the required standard of finish — without the surprises that come from fragmented delivery.

Why Greenwich Homeowners Work With Us

Greenwich is not a straightforward place to build. A large proportion of properties in SE10 sit within conservation areas or carry listed building status. The Victorian and Georgian homes that give the area its character also come with structural realities — removed chimney breasts, shallow foundations, complex loft structures and party wall considerations with terraced neighbours.

We have worked through all of it. We understand what Greenwich planners look for, how to handle listed building applications and how to deliver high-spec work within the constraints that come with period properties in SE10 and SE3.

If you are tired of thinking, “Where do I even start with a project this size?” or “How do I know the design will actually work with planning?” — that is exactly the conversation we are set up to have.

Services – S&M Solutions Ltd, Design and Build Contractors London

We have worked across Greenwich and SE10 for over a decade — on Victorian terraces, Georgian townhouses, 1930s semis and Grade II listed properties. We understand the local planning constraints, conservation area rules and structural quirks that come with homes in this part of London. That knowledge is built into every project from day one.

Comprehensive Planning

Every project starts with a paid site visit at your Greenwich property. We look at what you want to achieve, the budget you are working with and the constraints on site. You get a straight, honest view of what is achievable before moving further into design or construction.

Creative Design

Our in-house design team develops the full scheme — architectural drawings, structural calculations and specification work. We submit planning applications and manage the process with the Royal Borough of Greenwich, including listed building consent where required.

Quality Construction

Before a single brick moves, you will have a detailed fixed-price quotation. Our in-house team carries out the construction, supported by trusted specialist subcontractors where needed. You have one named project manager on site throughout.

What does a design and build service include?

Our design and build service covers the entire process from initial concept design and planning through to construction and completion. We handle architectural drawings, structural engineering, planning applications, all trades, building control, and final sign-off. Everything under one contract, one team, one point of accountability.

Is design and build better than hiring separate designers and builders?

For most residential projects in Greenwich, yes. When design and construction are managed separately, decisions made at design stage often don't account for how things actually get built which leads to cost increases and delays on site. We design with buildability and cost in mind from the start, which means fewer surprises when construction begins.

How much does a design and build project cost in Greenwich?

Our projects start from £100k. A straightforward rear extension with kitchen fit-out typically starts around that figure in SE10. Full house renovations, loft conversions with layout changes, or heritage work on listed properties will sit higher depending on scope and specification. We'll give you a clear, fixed-price quotation before any work begins.

Do you handle planning permission and building regulations?

Yes both. We prepare and submit planning applications to the London Borough of Greenwich, manage any consultation process, and handle all building control submissions and inspections through to final certificate. For listed buildings and conservation area properties in SE10, we also manage listed building consent applications.

Can you work with existing drawings?

Yes. If you already have architectural drawings or planning permission in place, we can take those on and move straight to detailed design development, costing, and construction. We'll review what you have, flag anything that needs updating, and take it from there.

About Our Process in Greenwich

1.

Inquiry

Tell us about your project by phone, email, or the contact form below. We'll ask about your project vision, timelines, and rough budget. If it sounds like a good fit, we'll arrange the next step.

2.

Paid Site Visit and Estimate:

We carry out a paid site visit at your Greenwich property. We assess the site, discuss design options, and provide a transparent, detailed estimate. A proper site visit and accurate estimate takes real time and care the fee covers that, so the work we do before a contract is signed is given the same attention as the work after it.

3.

Project Kick-off and Progress

Once the contract is signed, we begin promptly. You'll have access to our online project portal so you can follow progress in real time, and we hold fortnightly on-site meetings to keep you informed at every stage without the need to chase.

4.

Completion and Aftercare

We carry out a full walkthrough with you before handover. Building control sign-off, warranties, and aftercare instructions are all provided. Our commitment doesn't stop at practical completion.
