There are three main types of property extensions and the one we recommend for your property will depend on a number of factors including property style, available space, planning regulations, your budget and needs.

Generally involves building out 1.25m to the side of the property and finishing flush at the back of the main part of the house. Clients can then choose to have either a single or double storey build.

Where the end of the property is extended to approximately 5m x 3m (STPP) and can include huge roof windows to allow maximum natural light into the newly created space.

Involves building an extension to the side and rear of the property, sometimes extending 3 to 4 meters into the garden. This creates a huge kitchen diner living space for the family.

Space2 were a good choice for us. The design phase was excellent. The architects are talented and were excellent at providing solutions and ideas to maximise space. Very pleased with the end result. Recommend using them.
I was impressed with the quality of workmanship and the politeness of the contractors, I will recommended Space2 to my friends. They finished our loft conversion ahead of time and were very obliging with our requests for small alterations to the plan. I am planning a kitchen extension later this year and will use Space2 again.
Space2 made the loft conversion for us. They met all our expectations. The builders were wonderful, reliable and very professional. We highly recommend Space2 for any loft conversion.
We did a loft conversion and a small toilet. Our worry was that we had only six weeks to get everything completed as we had a newborn 4 weeks before the work started; everything was completed on time with high professionalism and excellent project management and great contractors; would recommend Space2 to anyone, great team, great experience.
