At S & M Solutions Ltd, we specialise in design-led residential construction, delivering carefully considered extensions, loft conversions, and full-home renovations across London.

Our work is centred around fully managed Design & Build projects, where architectural intent, technical delivery, and construction quality are aligned from the outset. This approach allows us to maintain exceptional standards, clear accountability, and a smooth, well-structured process from concept through to completion.

We work with discerning homeowners who value quality, clarity, and long-term value — and who are seeking a contractor capable of managing complex residential projects with confidence and precision.

Our Core Services

Bespoke Design & Build Solutions

A fully integrated service combining architectural design, technical coordination, and construction delivery under one team. Every project is carefully planned, cost-controlled, and managed from start to finish.

Home Extensions

Design-led rear, side, and wrap-around extensions that enhance both living space and architectural character, delivered with a strong focus on build quality, detailing, and long-term performance.

Loft Conversions

High-spec loft conversions designed to integrate seamlessly with the existing home — including dormers, mansards, and complex structural alterations.

Full Home Renovations

Comprehensive refurbishments and internal reconfigurations, often involving structural works, services upgrades, bespoke joinery, and refined finishes throughout.

New Build Developments

Bespoke residential new builds undertaken on a limited, carefully selected basis where the project aligns with our design-led approach.

External Works as Part of Extensions & Renovations

External and garden works delivered only as an integrated part of a wider extension or renovation project. This may include high-quality paving, terraces, retaining walls, drainage, and architectural external finishes designed to complement the home as a whole.
We do not offer external works as a standalone service.

Our Delivery Capability

All projects are delivered by our in-house team and trusted specialists, allowing us to retain full control over quality and coordination throughout the build.

 

This includes:

  • Structural alterations and steel installations

  • Reinforced concrete and underpinning (where required)

  • Bespoke carpentry and joinery

  • Roofing and architectural glazing

  • Plumbing, heating, and modern building services

  • Electrical installations and smart home systems

These elements form part of our fully managed Design & Build projects and are not offered as standalone services.
