House Extensions South London

House Extensions Construction Experts

Move house? Or just build the space you need right where you are?

We build smart, solid house extensions across South London that give you more room — without the madness of moving.

Whether you need a bigger kitchen, a ground-floor bedroom, or a full-width rear build that finally makes your home work for your family, we’ve got the people, the tools and the local know-how to make it happen.

We don’t outsource the work, and we don’t mess you about. We just build it the way you want it.

Why a House Extension Makes Sense In South London

You love your home. You love the area. You just don’t have enough space. That’s where we come in.

A house extension gives you:

  • More room without changing postcodes
  • A layout that works better for how you actually live
  • A boost in resale value without a fight with the estate agents
  • And the freedom to stay put while still making big changes

 

Most South London homes — from the classic semis near Lordship Lane to the bigger detached properties in Dulwich Village — have potential just waiting out the back or side. We turn that into proper square footage you’ll actually use.

What We Build

We don’t push you into a pre-set package. We build what you decide you need.

Rear Extensions

Straight out the back. Great for bigger kitchens, open-plan living and dining, or making a home that actually fits your life.

 

Side Return Extensions

Perfect for Victorian terraces with wasted alley space. Turns a dark, narrow kitchen into a bright, wide one.

Wraparound Extensions

A side return and rear extension combined. Gives you a whole new section of house. More light, more room, more use.

Double Storey Extensions

Need space up and down? We build full-height extensions that give you another bedroom, an extra bathroom, or both.

Garage Conversions

Don’t use the garage for anything but boxes? We’ll turn it into a proper room that earns its keep.

Not sure what fits your property? We’ll come out, take a proper look, and walk you through your options.

The Work Process

It starts with a visit. Not from someone in a shiny suit — but a skilled builder or engineer who knows what to look for.

We check the structure, foundations, drainage, access, and layout. Then we design the build around your home — and your budget.

Once you’re happy, we handle the rest:

  • Planning applications (if needed)
  • Structural calculations
  • Building regs
  • Foundations, brickwork, roofing
  • Plumbing, heating, electrics
  • Plaster, painting, and finish

 

You’ll know what’s happening. You’ll get straight answers. And the build won’t drag on for months longer than it should.
