Loft Conversions
Loft Conversions
We design and build loft conversions across Richmond and South West London, turning unused roof space into bedrooms, bathrooms and studies that feel part of the house.
Overview
In many South West London homes the loft is the largest unused space in the house. Converted well, it can become a main bedroom with an en-suite, a floor for the children or a quiet place to work, without giving up any of the garden.
A loft conversion touches the whole house: the structure, the roof, a new staircase and the fire safety of every floor below. We design and build it as one project, so the new rooms sit comfortably with the rest of the home.

- New staircase and landing
- Bedrooms, en-suites and storage
- Interior fit-out and finishes
Types of loft conversion
-
Rooflight conversion
The simplest option. The roof keeps its shape and rooflights bring in the daylight. It suits lofts that already have good headroom.
-
Dormer conversion
A box-shaped addition built out from the rear roof slope, adding full-height floor space. On many terraces an L-shaped dormer also runs over the rear addition.
-
Hip-to-gable conversion
For semi-detached and end-of-terrace houses with a sloping side roof. The side is built up into a vertical gable, often together with a rear dormer.
-
Mansard conversion
The rear roof slope is rebuilt at a steep, almost vertical angle, giving the most space. Mansards usually need planning permission.

Staircase & Fit-out
The new stair, then services, joinery and finishes.

Handover
Building control sign-off and a finished new floor.
Planning and building regulations
Many loft conversions can be built under permitted development, so planning permission is not needed, as long as the work stays within set limits on volume, height and materials. Mansards, dormers facing the street and homes in conservation areas usually need full planning permission, and some streets have an Article 4 direction that removes permitted development rights altogether.
Whichever route applies, every loft conversion must meet the Building Regulations. These cover the structure, fire safety and a protected escape route, the new staircase and its headroom, insulation and ventilation. If you share a wall with a neighbour, the Party Wall Act will usually apply too.
We check which route your home needs at the start, prepare the drawings and coordinate the structural engineer, building control and party wall notices as part of the project.
- Permitted development or planning permission
- Lawful Development Certificate where useful
- Structural calculations
- Building control approval
- Fire safety and escape route
- Party wall notices
Frequently asked questions
Is my loft suitable for a conversion?
Most houses with a pitched roof can be converted, but the headroom, the roof structure and where the new staircase can go all make a difference. We start with a survey and tell you honestly what is possible.
Do I need planning permission?
Often not, because many loft conversions fall under permitted development. Mansards, dormers facing the street and homes in conservation areas usually do need permission. We confirm the right route for your house before the design goes too far.
Can we stay at home during the work?
In most cases, yes. Much of the work happens in the roof, and the staircase is usually opened up into the house later in the build. We plan the sequence with you to keep disruption to a minimum.
Who handles building control and party walls?
We coordinate building control inspections and the structural engineer as part of the project, and we will help you put the party wall notices in place with your neighbours where they are needed.
