Bespoke home extensions built around your Cheadle property
Every home in Cheadle is different, so we build every kit to your exact specification. Your panels are cut, prepped and assembled in our factory, then delivered to site ready for a rapid installation.
We supply single storey extensions to the rear, to the side, or as a stand-alone structure. Popular projects include kitchen extensions, larger living rooms, dining spaces, downstairs bedrooms, playrooms, studies and annexes.
Because the work happens off-site first, there is far less mess and disruption at your property. Many builds are watertight in just a few days.
Why homeowners in Cheadle choose Extension Kitz
You get more than a supplier. You get a proven system and a team that manages the detail from first design to final installation. Here is what that means for your project.
- Faster build times. Panels arrive pre-cut and prepped, so installation is quick and predictable.
- Less site disruption. Most of the work is done in our factory, keeping your home and garden clear.
- Warmer rooms. Our wall system reaches a 0.15 U-value as standard, so your new space stays comfortable and cheaper to heat.
- Stronger structures. A finished SIP build is three times stronger than a brick wall and seven times stronger than timber frame.
- More usable space. SIP walls are slimmer than traditional build, giving you extra room inside.
- Controlled quality. Every kit is made under factory conditions with strict quality checks.
These benefits make a real difference on Cheadle’s mix of period homes and modern semis, where space, warmth and finish all matter.
What is a SIP extension?
A Structural Insulated Panel, or SIP, is an insulating foam core sandwiched between two structural boards. The result is a building system that is exceptionally strong, energy efficient and cost effective.
SIPs are light, so they can often rest on a simple concrete base or existing foundations where approved. This can reduce the cost of substructures and load-bearing internal walls. You can learn more about our SIP panel system and how it compares to conventional methods.
The panels also have excellent fire resistance and are not attractive to pests. It is a smart, modern way to extend a home in Cheadle.
From design to delivery: how the process works
We keep things clear at every stage so you always know what to expect.
Planning and design
You decide on the design and dimensions of your extension. Some customers use an architect, while others rely on the expert advice of our in-house design team. We can also help with planning permission where it is needed.
Your quotation
To give a firm price, we need drawings with precise measurements covering the wall and roof dimensions, plus door and window positions. For an early figure, our quick quote gives you an indicative cost so you can plan your budget.
Fabrication and delivery
Once your order is placed, our factory starts work on the panels. Your extension is assembled in the factory to check the fit, then carefully dismantled and numbered for easy reassembly on site. Kits are usually delivered within 10 to 15 days of order.
Installation
Our extension kits can be installed by our own team or one of our preferred installers. With everything prepped in advance, on-site time is kept to a minimum.
What can you build in Cheadle?
The system is flexible, so your options are wide. Homeowners across Cheadle use our kits for:
