What are the key ingredients for a fabulous new kitchen?

Designing and building your dream kitchen is a popular choice for our home renovators in the Manchester, Merseyside and Chesire areas.

As the main family hub of the house, a kitchen space is important.

Extending your home kitchen area requires flow and movement allowing for many activities such as cooking, entertaining and relaxing. Often kitchens double up as work from home spaces. Or there’s a need to bring the outside in.

As we are a vetted building company, a member of the Guild of Craftsmen, we have been chosen by leading brands to offer amazing materials to bring your dream kitchen to life.

We spend time with you evaluating and reaching solutions to fit your needs.

Single-Storey Extensions: More Space. More Possibilities.

If you’re looking to add real space and value to your home, a single-storey extension is one of the smartest investments you can make.

It’s a clean, simple way to extend your ground floor and give yourself the breathing room you need—whether that’s for a new kitchen-diner, utility room, home office, or a place to finally relax without bumping elbows.

We don’t just build boxes on the back of houses. We design spaces that actually work—with natural light, proper flow, and full integration into your existing home. Think open-plan living, sliding doors, or even a space that brings the outdoors in.

As a Guild of Master Craftsmen member, we’re vetted and trusted to deliver quality. Our team handles everything from drawings and planning permission (if needed) to building regs, so there are no delays, surprises, or corners cut.

We’ll sit down with you, figure out what you need, and create a solid plan that fits your life and your budget—start to finish.

More room. More comfort. Built properly.

Two-Storey Extensions in Warrington, St Helens, Wigan & Surrounding Areas.
Twice the Space. One Straightforward Build.

If your family’s growing or your lifestyle’s changing, a double-storey extension gives your home the space to grow with you—without the cost or chaos of moving. We’ve helped homeowners across Warrington, St Helens, Wigan, Manchester, Merseyside and Cheshire turn their current homes into their forever homes.

You get more living space downstairs—ideal for open-plan kitchens, bigger lounges, or utility rooms. And upstairs? Extra bedrooms, bathrooms, or even a dedicated home office. It’s flexible, practical, and adds serious value.

We don’t do guesswork. We work closely with you to make sure your new space looks and feels like it’s always been part of the house.

From start to finish, we handle the planning permission, drawings, building regs, and full build. You don’t have to chase a dozen different trades—we’re your one point of contact from concept to completion.

Double the space. Done the right way.

Wraparound Extensions
Maximise Your Space Without Compromising Style

A wraparound extension gives you the best of both worlds—extending your home to the side and rear in one go. It’s the ideal way to open up your downstairs layout while adding serious square footage where it counts.

You get more room for a proper open-plan kitchen, dining, living, or utility area—and still have space for a home office or snug. Upstairs, it can create extra bedrooms or bathrooms without making the house feel unbalanced.

This type of extension makes a big impact, but only if it’s done right. Our team designs everything to flow with your existing home—so it doesn’t look like an afterthought. Just clean lines, smart use of space, and a build that feels like it was always meant to be there.

From drawings to final handover, we manage the full process under one roof. No chasing trades. No crossed wires. Just a team that turns up, gets on with it, and delivers exactly what was promised.

Clever design. Quality build. Zero hassle.

Traditionally Built Orangeries
Classic Look. Solid Build. Modern Comfort.

A traditionally built orangery gives you that grand, high-end feel—without looking like a bolt-on. With brick parapet walls to the front and sides, this isn’t a conservatory dressed up to impress. It’s a proper extension of your home, built to last and designed to blend in seamlessly.

You get the natural light of a glazed roof, combined with the thermal efficiency and privacy of solid walls. It’s perfect for a light-filled living room, kitchen extension, or relaxing garden room—whatever suits your space and lifestyle.

Designed from scratch to fit your home, with clean lines, proper proportions, and a finish that respects the character of your property. It looks like it belongs—because it’s built that way.

We manage everything from initial concept to the final coat of paint—design, materials, structure, and full build. No sales patter,  just a team that turns up, gets stuck in, and builds it properly.

Timeless style. Solid structure.
