Extending your property will not only provide extra space it will also add extra value, so it is important to get it right. We work closely with architects, structural engineers and planning officials to ensure that all work is done to the highest standards and conforms to all local and national regulations.

Loft & Basement Conversions

Sometimes the extra space you are looking for can be found above your head or below your feet. Be it an extra bedroom, home office, extra living space or storage we can help you realise this potential by creating fully serviced rooms or simply create additional useable space. Our eco advice on insulation and soundproofing can make your property greener and reduce your energy costs.

Bathroom Installation

Creating that peaceful haven or providing the wow factor for buyers- a bathroom refurbishment can transform a property. We can offer a full design, supply and installation service or part thereof with our team specialising in contemporary and period designs including wetrooms.

Kitchen Fitting

The kitchen is the heart of the home and we understand that everybody’s requirements, visions and budgets are different. We make sure we know what our clients needs and each space is refurbished to individual design whether that is bespoke hardwood or off-the-shelf modular units. Our service can start at the design stage or be limited to solely installation.

House Renovations

A new home, face lift or development opportunity – property renovations are exciting projects to undertake but can be daunting and time consuming without the right experience. We are happy to take on projects of all sizes from full refurbishments to a finishing service, offering as much or as little in the way of advice as you require while always providing a high quality finish.

Carpentry and Joinery

From windows and doors through to floors and furniture we can offer the solution you are looking for. Our experience of balancing the old with the new has given us practical knowledge of how to create bespoke storage solutions sympathetic to your home and your requirements. We are experienced in fitting and sourcing high quality hardwood, softwood, new and reclaimed wooden floors and specialise in restoring original floors.

Plumbing and Electrical

From full re-wires and new boilers to under-floor heating, additional radiators, sockets or lights we offer a full range of electrical and plumbing services. Our fully qualified experienced tradesmen can undertake all size jobs.

Plastering, Tiling & Decoration

A high quality finish can not be underestimated – we undertake all final finish services with a focus on the finer details.
