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.

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, 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.

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.
