Extending your home is a cost-effective and low-stress way to give your family the space they need. House extensions are fully customisable to individual properties and requirements, enabling you to create exactly what you need. Everything from the overall size to kitchens and bathrooms is tailored around you.
Based in Runcorn, the builders at Craft Joinery & Building Ltd provide a start-to-finish service for home extensions in Warrington, Altrincham, Lymm and all the surrounding areas we cover. Each project starts with a thorough consultation, including a home survey, professional advice and feasible plans. This is vital to delivering an extension which you will love for years to come.
If a traditional extension isn’t right for you, we also offer conversions and garden rooms.
Please explore our gallery to see examples of previous extensions and other projects we have completed.


Our team can build all types of home extensions, giving you the utmost flexibility. If you want to utilise awkward space to the side of your house, a side-return extension is ideal. Rear-facing, wraparound and double-storey house extensions are best for large additions.

We provide full project management, organising and overseeing every stage. As part of this, we ensure work is completed on time, on budget and in compliance with regulations.
