Loft, Conservatory and Garage Conversions in Runcorn
Converting Spaces Across Warrington and the Surrounding Areas

Converting a loft or garage is the perfect way to add space without extending. The process takes a room you already own and transforms it, creating a multipurpose space that you can visit every day of the year. At Craft Joinery & Building Ltd, we take the strain out of garage conversions and all other styles – making the development as affordable and hassle-free as possible for homeowners in Runcorn, Chester, Lymm Warrington and the surrounding areas we cover.

Our builders work in tandem with our in-house specialists to perform all building services for the project. We ensure compliant conversions in line with building regulations, modernising your old space with meticulous care. 

You can rely on us for the following benefits and services:

  • A free quotation and detailed, creative advice

  • Garage conversions with brickwork and insulation

  • The stripping of all previous materials

  • Rooflight, mansard and dormer loft conversions

  • Hip-to-gable structural work for your attic space

  • Conservatory conversions for a warmer environment

  • Kitchen conversions with all aspects carried out

  • Energy-efficient installations and a decorative touch

Craft Joinery & Building Ltd assists homeowners who wish to improve conditions but don’t know where to start. If this sounds familiar, don’t hesitate to get in touch.

The Ideal Choice for Loft, Conservatory and Garage Conversions

Bringing over 60 years of experience to conversions, our builders work flexibly to transform your space. We listen to your needs at the beginning of the project, and as a family-run business, provide regular updates and answer your questions or concerns. By choosing our team, you can relax while we carry out all services, from heating and plumbing to electrical wiring.

Garage Conversions

A garage that serves as a storage room can be put to better use, especially for homeowners with off-street parking. Create a large office where you can push your career in the right direction, build a gym for personal fitness or form a double bedroom that gives friends a place to stay. Our team will remove the previous doors and windows to make the space a welcoming part of the house, with bricklaying, insulation, painting and decorating delivered to a high standard.

Loft Conversions

Dormer conversions prove popular across the UK, adding extra headroom and traditional windows. Alternatively, you could choose hip-to-gable work that turns a slope into a vertical wall or ask about mansard conversions that restructure the roof for maximum space – the ideal choice for those wanting a beautiful en-suite. Rooflight installations make the environment brighter, and with all conversion work from our experienced builders, you can sit and stargaze or invite friends to your vibrant and professionally designed conversion.

Much like garage conversions, loft work in Runcorn, Warrington, Chester or the nearby areas can often fall under permitted development. A member of the Craft team will be able to advise based on the details of your project.

Kitchens and Conservatories

Does your conservatory run cold in the winter due to the abundance of glass? Perhaps you would prefer a traditional extension, with brickwork, heating, plumbing and other modern luxuries. At Craft Joinery & Building Ltd, we can convert your conservatory to suit the look of your home. Likewise, our builders could transform a space to expand the kitchen in either a classic or contemporary style. No matter your choice, our team can convert any space while sticking to your budget and the timeframe agreed.

From converted lofts to full-scale garage conversions, our builders do it call. Call 01928 775 990 or 07958 473 567 for conversion work in Runcorn, Warrington and the nearby regions.
