Create the extra space you need while keeping full control over the final look with an Eco Extend shell only extension. We handle the structural work - foundations, walls, roof, insulation, windows, doors and external finishes - so you get a complete, weather-tight “blank canvas” ready for your own kitchen supplier, bathroom fitter or interior designer. Based in Liverpool, we work with homeowners, self-builders and developers who want a high-quality structure without being tied to a particular fit-out package.
Every shell only extension we build uses Dragonboard within the structure, creating a strong, moisture and fire-resistant envelope that performs brilliantly in the British climate. With modern insulation, quality roofing and careful detailing, your new space is designed to be warm, efficient and ready for services to be run exactly where you want them. We deliver shell only extensions across Liverpool, Merseyside, the wider North West and on selected projects nationwide.

A shell only extension gives you the core structure without the internal finishes. We take the project up to a watertight, secure stage: groundworks, concrete slab, walls, roof, insulation, external cladding or brickwork, plus windows and doors as agreed. Internally, you’re left with a clean, service-ready shell for your chosen trades to complete - whether that’s a bespoke kitchen, luxury bathroom, underfloor heating, flooring or decoration. It’s a cost-effective way to separate the building phase from the interior, and ideal if you already have preferred suppliers.
From compact rear extensions on terraced properties to larger side and wrap-around shells for semis and detached homes, we tailor each project to your plot, budget and plans for the interior. Our team understands how to coordinate with other contractors, leaving clear access and service routes for plumbers, electricians and kitchen or bathroom installers. Whether you’re in Liverpool, Wirral, Sefton, Cheshire, Lancashire or elsewhere in the North West, you get a well-organised build and a shell that’s properly prepared for the next stage.
Typically the shell includes foundations, slab, external and internal structural walls, roof, insulation, external finishes, and agreed windows and doors, taken to a secure and weather-tight stage. Services and internal finishes such as plastering, flooring, kitchens and bathrooms are usually left for your own contractors.
Yes. A shell only extension is always cheaper than asking for the same project on a full turnkey basis. Because we focus on building the structural, weather-tight envelope, shell only packages are often more than 50% cheaper than turnkey on the main build cost.
With a shell only extension, you pay us to take care of the structure, foundations, roof, windows and doors so the space is secure and watertight. After that, you have complete freedom to design and finish the interior exactly how you want it. You can choose your own kitchen or bathroom supplier, flooring, lighting and décor, shop around for the best prices and bring in trusted local trades at your own pace.
This approach keeps the contractor cost down, gives you far more control over style and budget, and lets you phase the spend to suit your finances and timeline. We can still provide a full turnkey option if you prefer everything managed for you, but most clients find shell only offers the best value and flexibility.
Yes. Even for shell only projects, we can handle planning applications, drawings and building control submissions, then liaise with inspectors up to the point where the shell is signed off, ready for your internal trades to continue.
We can work to agreed layouts, opening sizes and service positions so your chosen kitchen or bathroom supplier knows exactly what to expect. We’ll provide key structural and dimensional information and, where needed, speak to them during the design phase to avoid clashes later on.
If you decide you’d like us to carry on beyond the shell stage, we can provide a separate quotation for internal fit-out, subject to availability. Many clients still prefer to keep the shell and interiors as two distinct packages, but the choice is yours – our priority is delivering a solid, well-detailed structure that sets your project up for success.
