Architecture & Engineering

Design-led planning, technical coordination, and engineering support for residential projects across London.

At S & M Solutions Ltd, we deliver design-led residential projects across London through a structured Design & Build approach, working with homeowners who value careful planning, technical clarity, and high-quality construction.

Every project begins with a defined pre-construction phase led by our sister company, S & M Design Ltd, where planning, structural engineering, and building compliance are fully developed before construction pricing is finalised. This ensures key design and technical decisions are resolved early, reducing uncertainty and allowing projects to progress into construction with confidence.

Once approvals and technical design are in place, delivery transitions seamlessly to S & M Solutions Ltd, maintaining continuity from concept through to completion under a single coordinated team.

Whether undertaking a loft conversion, extension, renovation, or bespoke new build, our integrated process provides clarity, consistency, and design integrity at every stage of the project.
