What We Do

Four things, done exceptionally well.

We focus on the renovations that make the biggest difference to how you live, and we sweat every detail from first sketch to final handover.

Loft Conversions

Turn unused roof space into a beautiful bedroom, office or suite: dormer, hip-to-gable, mansard and Velux conversions.

  • Dormer & mansard
  • Hip-to-gable
  • En-suite bedrooms
  • Staircase design

Extensions

More space, more light, more value. Single or double-storey, rear, side-return and wrap-around extensions built to last.

  • Rear & side-return
  • Double-storey extensions
  • Open-plan kitchen-diners
  • Planning & building control

Full Home Renovations

End-to-end transformations that reimagine your whole home: structure, layout, finishes and everything between.

  • Kitchens & bathrooms
  • Structural reconfiguration
  • Rewiring & re-plumbing
  • High-quality finishes throughout

Bathrooms

Hotel-quality bathrooms and en-suites, from spa-style wet rooms to family bathrooms, fitted to a flawless finish.

  • Wet rooms & walk-in showers
  • Freestanding baths & en-suites
  • Large-format tiling
  • Underfloor heating
Included As Standard

Underfloor heating, free of charge.

Every new extension we build comes with warm, even underfloor heating included as standard, with no added cost on full projects. A more comfortable, better-finished space from the ground up.

See The Difference

The same home, transformed.

Our favourite part of the job is the reveal, the moment a tired, dated property becomes something you're proud to come home to.

Good To Know

Frequently asked questions.

The things homeowners ask us most. Can't see your question? Just get in touch. We're happy to talk it through.

Yes. We offer a free, no-obligation consultation and quote anywhere across London. We'll visit, talk through your ideas, and give you a clear, itemised price, with no pressure to proceed.

We work right across London and the surrounding boroughs, with a central London correspondence address in Fitzrovia. If you're just outside London, get in touch and we'll let you know if we can help.

Yes. We can manage planning applications and building control sign-off on your behalf, so you don't have to deal with the council yourself. We'll guide you through what your project needs from the very first consultation.

Every project is different, but as a rough guide for on-site build time: a bathroom is around 2 to 4 weeks, a loft conversion around 6 to 10 weeks, a single-storey extension around 8 to 16 weeks, and a full home renovation around 3 to 6 months. We'll give you a realistic timeline before any work begins.

Yes, we're fully insured, and every part of your project is carried out by certified trades working to current building regulations.

Yes. Every project comes with a workmanship warranty, so you can be confident the work is built to last.

We use clear stage payments tied to project milestones, so you only pay for work as it's completed, never a large sum up front. The full payment schedule is set out in your itemised quote before we start, with nothing hidden.

In most cases, no. Many projects, loft conversions especially, let you stay at home, as the work is contained to one part of the home. We keep things tidy, dust-controlled and secure throughout. For larger or whole-home renovations it can be more comfortable to move out for part of the build, and we'll always be upfront with you about that during planning.
