Design and Build Contractors in Charlton

Extensions, loft conversions, renovations and heritage refurbishments across Charlton and SE7.

There are a lot of moving pieces in a building project in Charlton: design decisions, planning requirements, structural input, builders, trades and finishing work — all needing to line up properly from the start.

When those stages are not coordinated, homeowners are left chasing updates, managing delays and trying to keep control of the budget. That is rarely where you want to be during a major extension, loft conversion or renovation.

At S & M Solutions, we manage your Charlton 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 Charlton

Our design and build service is set up to manage the full process, from initial ideas and planning through to construction, finishing and completion. Every stage is approached with buildability, cost control and quality of finish in mind, so responsibility stays clear throughout.

Whether you are planning a house extension, loft conversion, full refurbishment or wider renovation in Charlton, we bring the same coordinated approach to every project. You deal with us. We manage the design, planning, construction and the details in between.

Experienced Design and Build Contractors in Charlton

Charlton is a varied area to build in. Around Charlton Village and Charlton Church Lane, many homes have period character and conservation considerations. Towards Charlton Park, Kidbrooke and the surrounding residential streets, there are also 1930s semis and family homes that can work well for rear extensions, loft conversions and full refurbishments when the design is handled properly.

With over 22 years in construction and more than 180 projects completed across South East and Central London, we understand how to coordinate design, structural input, planning and site delivery. As FMB members and TrustMark accredited contractors, with NVQ Level 6 construction site management experience, we bring practical build knowledge into the process from the start.

Why Charlton Homeowners Work With Us

Charlton projects often need careful planning from the beginning. Some properties sit within or close to conservation settings, while others have the structural realities that come with older London homes — existing alterations, party wall considerations, roof constraints and layouts that need a practical design approach.

That is why homeowners work with us: one team managing design, planning, structural input and construction. We are based nearby in Blackheath and have worked across this part of South East London for years, including projects close to Charlton in Blackheath, Greenwich and Plumstead.

We bring local South East London experience to projects in Charlton, where extensions, loft conversions and refurbishments often need to balance design ambition with planning, structure and the character of the existing home. That knowledge is built into the process from day one.

Comprehensive Planning

Every project starts with a paid site visit at your Charlton 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 design team develops the scheme around your property, your goals and the local context. This can include architectural drawings, structural calculations, specification work and planning support where required, helping to keep the design buildable from the outset.

Quality Construction

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

What does a design and build service include?

Our design and build service covers the full process from early concept design and planning through to construction, finishing and completion. We can manage architectural drawings, structural input,planning applications, building control, trades and final sign-off, so your Charlton project is handled by one coordinated team with one clear point of accountability.

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

For most residential projects in Charlton, 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 Charlton?

Our projects start from £100k. A straightforward rear extension with kitchen fit-out typically starts around that figure in SE7. 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. We can prepare and submit planning applications, coordinate the required drawings and structural information, and manage building control submissions and inspections through to completion. For Charlton properties affected by conservation considerations or local planning constraints, we help factor those requirements into the process early.

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 Charlton

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 Charlton 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.
