Customer Satisfaction

Residential Extensions,
Conversions & Refurbishments

Whether you are looking to make improvements to your home so it is better suited for your lifestyle and tastes, or are interested in adding value when you come to sell, we can help.

Whatever your individual requirements, from decorating, through bathroom updates or new drives & patios, up to large fully managed house extensions, we can utilise our wealth of experience and ideas to accurately interpret and deliver your design concepts and dreams.

Commercial Alterations & Major Maintenance

We understand that busy and successful businesses need a very efficient and professional business to deliver improvements to the properties. With many years of experience in the fitting out, alteration and major maintenance of hotels, restaurants and offices, we are just such a partner.

Above all, we understand that such projects need to be delivered with the twin priorities of certainty and quality, so are very used to working to tight deadlines, often working around occupants whose ability to continue their normal duties – as well as their personal safety – is paramount.
