Are you looking to create extra space at your property without the hassle of a traditional extension? Extension Kitz provides high quality, bespoke garden room kits to homeowners throughout the North West of England. From Cheshire to Cumbria, and Merseyside to Greater Manchester, we help you transform your outdoor space into a functional, stylish, and comfortable living area.

Our garden rooms are built using advanced Structural Insulated Panels (SIPs), ensuring they are energy efficient, durable, and quick to assemble. Whether you need a home office, a gym, or a relaxing summer house, our kits offer the perfect solution.

Why Choose a Garden Room for Your North West Home?

A garden room is a cost effective way to add valuable square footage to your home. Unlike a conservatory which can be too hot in summer and too cold in winter, our insulated garden rooms are designed for year round use. They provide a distinct separation from your main house, offering privacy and a dedicated environment for whatever you need.

Our customers across the North West use their garden rooms for a variety of purposes:

Home Offices: create a professional workspace just steps from your back door, perfect for remote working without household distractions.
Garden Gyms: save on gym memberships and travel time with your own private fitness studio.
Hobby Rooms: enjoy a dedicated space for painting, crafting, music, or writing.
Family Rooms: give teenagers their own den or create a cinema room for family movie nights.
Guest Accommodation: provide a comfortable and private space for friends and relatives to stay.

The Superior Quality of SIPs Technology

We use Structural Insulated Panels (SIPs) for all our garden room kits. This modern construction method offers significant advantages over traditional timber frames or brick buildings.

Unbeatable Insulation

SIPs consist of an insulating foam core sandwiched between two structural facings. This design creates a building with exceptional thermal performance. Your garden room will retain heat in the winter and stay cool in the summer, keeping energy bills low and comfort levels high. This is particularly important for the variable weather we experience here in the North West.

Speed of Construction

Time is precious. A traditional brick extension can take months to complete, with builders on site every day. In contrast, our pre cut SIPs kits can be assembled in a matter of days. Because the panels are precision manufactured in our factory, they slot together perfectly on site, minimising waste and disruption to your daily life.

Design Flexibility

Because we manufacture the panels ourselves, we can create a garden room to your exact specifications. You are not limited to off the shelf sizes or designs. Whether you have a small urban garden in Liverpool or a large plot in the Lake District, we can design a kit that fits your space perfectly.

What Do Our Extension Kits Include?

Our garden room kits provide the complete structural shell for your new building. We aim to make the process as simple as possible for you.

Your kit will include:

Custom SIPs Panels: Walls, floor, and roof panels cut to your specific dimensions.
Structural Timber: All necessary joining splines and structural timber.
Pre Cut Openings: Door and window apertures cut to size in our factory.
Assembly Guide: A comprehensive manual to guide you through the build.
Numbered Parts: All components are clearly labelled for easy identification.

We pre assemble every kit in our factory before delivery to ensure quality and precision. This guarantees that when your kit arrives at your property, everything will fit together seamlessly.

How much do SIPs extension kits cost?

Every SIPs extension kit is bespoke, designed and manufactured to your exact requirements. This means pricing will vary depending on the size, design, and finishes you select. To help you plan, you can use our quick quote calculator on the website for an instant, no-obligation estimate tailored to your project. Once your design is finalised and dimensions are confirmed, we will provide a fixed cost, giving you total peace of mind for your budget.

Customising Your Garden Room

Your garden room should be unique to you. Once the structural shell is up, you have the freedom to finish the exterior and interior to match your style.

Cladding: Choose from cedar, composite, or render to complement your existing home.
Glazing: Install large bifold doors to open up the space to the garden, or picture windows to frame a view.
Roofing: Select EPDM rubber roofing for a modern look and long lasting weather protection.

Our team can offer advice on the best materials and finishes to suit your location and budget.

Will I need planning permission for my garden room?

Most garden buildings follow permitted development rules and don’t need planning permission; however, you should check that your project qualifies before you order your kit.

Planning officers are mainly concerned about three issues:

The dimensions of the project: The average size of a garden room in the North West is around 20 square metres, and most of our customers find this ample space.
The garden room’s proximity to your neighbour’s boundary: Your garden buildings should not be too near your neighbour’s boundary, overlook their garden, or look into their house.
The way you intend to use the garden room: If you plan to run a business which involves visits from customers or colleagues, there could be implications for parking and noise, which may require planning permission.

We have extensive experience in obtaining planning permission and are happy to advise you and answer any questions about the process. Always confirm details with your local planning authority before proceeding.
