More space. Better light. A home that works for how you live now.

Whether you're opening up the back of your home, adding a side return, or thinking about a loft conversion, a well-designed extension can transform everyday life. We help you make the most of your home — with elegant, energy-smart design that’s built to last.

Designed for Life, Not Just More Floor Area

A good extension does more than just add square metres. It should improve how your home feels, flows and functions — bringing in more light, better views of the garden, and spaces that genuinely support family life.

We don’t just ask “what can we add?” — we ask, what does your home really need?

Working with Period Homes in London

Most of the homes we work on are in conservation areas. Victorian terraces. Edwardian semis. 1930s houses with character. That’s our sweet spot.

We specialise in extending these homes with care — respecting the old, introducing the new, and handling planning applications with confidence. We understand what local planners are looking for and can advise you early on what’s likely to be supported.

Smarter, Warmer, Greener

Every extension is a chance to do better — better insulation, better daylight, better comfort.

We design with the future in mind: breathable materials, energy-efficient envelopes, and the option to retrofit alongside your extension work. Whether you want to meet EnerPHit standards or just keep the house warm in winter, we’ll guide you through what’s possible — and what’s worth doing.

Transparent Process, Honest Budgets

We’ve worked with many first-time renovators and know how important it is to feel informed and in control.

Every project starts with a pre-design appraisal to understand your brief, budget, and any planning constraints — before we sketch a single line. We’ll guide you through the options, flag potential risks, and make sure your extension is achievable, not just beautiful.

We also monitor costs closely during design to make sure your ambitions and budget stay aligned

Recent Extensions

Islington Loft Extension

Light-filled loft conversion in a Victorian terrace, Islington N1

This loft extension transforms the upper floor of a Victorian terraced house in the heart of Islington, North London. The brief was to create a calm, light-filled bedroom suite that feels private yet connected to the rest of the home.

We designed a sensitive mansard roof extension that blends seamlessly with the historic terrace, meeting planning requirements while delivering generous head height and improved spatial flow. Rooflights and carefully positioned glazing flood the interior with natural light, while bespoke birch plywood joinery makes efficient use of every inch.

The result is a warm, modern loft conversion with natural finishes and long views — a peaceful retreat that adds lasting value to a period home.

Rear Garden Room Extension

Zinc-clad garden room for a South London family home

This rear extension to an Edwardian villa in South London creates a bright, elegant living space that links the original kitchen to the garden. The brief was to improve light, flow, and access to the outdoors — while respecting the proportions and character of the existing home.

A zinc-clad volume was added, with full-width sliding doors and a deep overhang to provide passive shading and a strong garden connection. Oak parquet flooring runs throughout, grounding the space with warmth and natural texture. Overhead, rooflights bring soft daylight into the centre of the plan.

The result is a calm, contemporary garden room — a subtle but transformative addition to a family home.

Partial Wrap-Around Extension

Rear and side infill extension to a Victorian terrace in Walthamstow, East London

This partial wrap-around extension to a Victorian terrace in Walthamstow transforms the ground floor layout, unlocking generous new space for cooking, dining and family life. The design infills the side return and extends to the rear, creating a light-filled heart to the home that opens directly onto the garden.

Large-format glazing and carefully placed rooflights bring natural light deep into the plan, while exposed brickwork and natural finishes create warmth and character. The new layout improves connection between the kitchen, living and garden — supporting the flow of everyday life without feeling open-plan or boxy.

The result is a modest yet impactful extension that makes the most of a tight footprint — balancing light, material richness and spatial efficiency in a way that feels both contemporary and enduring.

FAQs

  • It depends on the size, scope and level of finish, but most of our extension projects start from £150k for build cost. We can provide realistic cost forecasts at the pre-design appraisal stage.

  • Sometimes, but not always. It depends on the level of disruption. We can talk through the pros and cons early on, so you can plan ahead.
