Loft Conversions in Greenwich, London

Design and Build Specialists for Period and Family Homes in SE10

Loft Conversions Greenwich SE10– S&M Solutions Ltd, Design and Build Contractors London

If you own a property in Greenwich and you’re running out of space, a loft conversion is often the smartest way to gain an extra bedroom, home office, or en-suite without the cost and disruption of moving.

At S&M Solutions Ltd, we design and build loft conversions across Greenwich, West Greenwich, Maze Hill and the SE10 area, delivering well-planned spaces that feel like they’ve always been part of the home — not an afterthought.

We work mainly on Victorian and Edwardian terraces, semi-detached houses, and family homes, where structure, access, and neighbours need to be handled properly from day one.

Loft Conversions Designed for Greenwich Homes

Greenwich properties come with their own challenges — conservation areas, party walls, tight access, and streets where parking and deliveries need planning. We deal with this every week.

Our team manages the full process:

  • survey and feasibility

  • architectural design

  • structural engineering

  • planning and Building Control

  • construction and finish

You deal with one company, not a chain of consultants.

Planning and conservation in Greenwich

SE10 sits at the heart of Maritime Greenwich, a UNESCO World Heritage Site taking in the Old Royal Naval College, the Queen’s House, the Royal Observatory and Greenwich Park. It’s one of the most heritage-dense pockets of London, and it shapes what’s possible with a loft conversion here more than in most areas we work in.

The Royal Borough of Greenwich has 23 conservation areas, and several sit right across SE10 and the surrounding streets — including Greenwich Park, West Greenwich and East Greenwich. West Greenwich and East Greenwich both carry an Article 4 direction, which is a step beyond standard conservation area status: it removes permitted development rights for most external alterations, including re-roofing, new windows and doors — not just the more visible dormer or roof-line changes. In these streets, a loft conversion will usually need a full planning application, not just a permitted development check.

Listed buildings are also common through the historic core, where any alteration — inside or out — needs listed building consent alongside standard planning permission.

We check all of this for you as part of the paid site visit, so you know from day one whether your street falls under permitted development, a full application, an Article 4 direction, or listed building consent — before any design work begins.

Popular Loft Conversion Types for SE10 Properties

Velux (Rooflight) Conversion

Ideal where head height is already good and planning needs to be kept simple. Minimal structural work and lower cost.

Dormer Conversion

The most common option in Greenwich terraces. Adds proper headroom and usable floor space for bedrooms and en-suites.

L-Shaped Dormer

Best for period homes. Creates space for multiple rooms or generous layouts and works extremely well for growing families.

Mansard Conversion

Full roof rebuilds that maximise space and value. Often used on higher-end homes and streets with consistent rooflines.

Our Proven Process

1.

Inquiry

Tell us about your project by phone, email, or the contact form below. We'll call and 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.

Do I need planning permission for a loft conversion in Greenwich?

Many loft conversions in SE10 fall under permitted development, particularly rear dormers on terraced houses. However, parts of Greenwich are in conservation areas, some of which carry additional Article 4 restrictions, and flats always require permission.

We’ll tell you upfront:

– what is possible
– what will need approval
– and what is worth doing (and what isn’t)

No guesswork, no wasted drawings.

Most loft conversions take between 8–12 weeks once work starts on site, depending on structure, access, and specification.

Cost depends on the structure, access, specification, and whether an en-suite or stair reconfiguration is needed — a Velux loft and a mansard conversion aren’t in the same conversation. Rather than a generic range that doesn’t reflect your actual property, we give you a proper figure at the paid site visit, once we’ve seen the space and understand what you’re trying to achieve.
