Loft Conversions South London

Building Experts In Loft Conversions

Build upwards. Stay local. Skip the estate agents.

If your South London home’s feeling tight, don’t start packing boxes just yet. You’ve already got extra room sitting quietly above your head — doing nothing. We turn that wasted space into something that works. A new bedroom. A proper home office. Even a full studio if that’s what you need. All without changing postcodes.

We’re local builders, based in Dulwich who like to do things properly. No delays. No mess. Just solid construction work, straight walls, and a new space that feels like it was always part of the house.

Why a Loft Conversion Makes Sense in South London

You’ve paid for the property’s footprint, so you might as well use every inch.

Here’s what a loft conversion gives you:

Extra space without eating into your garden
A whole new room without the circus of moving
A serious boost in value — no stamp duty, no stress
And a way to make your house feel bigger without buying more of it

South London properties — whether Victorian, Edwardian or modern — often come with untapped attic space. We turn that dead zone into something liveable, warm, and well-built. You’ll wonder why you didn’t do it sooner.

What We Build

There are no cut-and-paste jobs here. We design each loft to fit the house — and your plans for it. That said, here’s what’s popular:

Dormer Loft Conversions

That classic box-shaped extension. More headroom, square walls, and proper light. Works well on most terraces and semis in the area.

L-Shaped Dormers

Ideal for homes with rear extensions. Turns awkward corners into useful square metres. Common in parts of Dulwich Village and Lordship Lane.

Mansard Conversions

Blends neatly into period homes. A bit more structural work, but it gives you a full extra floor with proper windows and a pitched roof.

Hip-to-Gable Conversions

Perfect for end-terrace or detached houses. Converts that sloped side into straight, usable space. Good option for houses near Peckham Rye Park.

Not sure which one suits your home? We’ll come round and advise you on the best type of conversion based on your home and your intended use of the new space.

The Work Process

We don’t start with a brochure. We start with your roof.

Our structural engineer checks the timber, the load points, the walls, the access. From there, we draw up plans that work with your house — not against it.

Once you’re happy with the layout, we take care of everything:

Planning permission (if you need it)
Building regulations
Structural work and steel installation
Plumbing, electrics, and heating
Windows, flooring, and finishes

We don’t disappear halfway through or outsource the job to someone cheaper. We do the building. We finish it, so you can enjoy your new room upstairs.
