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.
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.
Many loft conversions in SE10 fall under permitted development, particularly rear dormers on terraced houses. However, parts of Greenwich are in conservation areas, 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.
How Much Does a Loft Conversion Cost in Greenwich?
As a realistic guide:
Velux / rooflight loft: from £45k–£60k
Dormer loft conversion: from £65k–£90k
L-shaped dormer or large layouts: from £90k+
Mansard lofts: typically £110k+
Costs depend on structure, access, specification, and whether an en-suite or stair reconfiguration is needed. We provide clear estimates, not vague ranges.
Velux (Rooflight) Conversion
Ideal where head height is already good and planning needs to be kept simple. Minimal structural work and lower cost.
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.
Full roof rebuilds that maximise space and value. Often used on higher-end homes and streets with consistent rooflines.
