We build basements throughout Hampshire and into Surrey, Dorset and Wiltshire. We offer a complete structural building service and a 10 year guarantee backed by Latent Defects Insurance. We are basement specialists, not house specialists. Never the less we build house walls for people who want zero heating bills for the lifetime of their new property.     This is a photo from a recent project. We build basements from reinforced, waterproof concrete using Polarwall insulating formwork and we drain externally or internally as appropriate. We built the basement beneath this timber frame garage and granny annexe. Polarwall above ground would have been better for the environment. It was built in difficult, waterlogged ground with a very high water table. Our method of building walls is sometimes chosen for above ground as well. Here we helped a contractor meet level 3 of the Code For Sustainable Homes on a development of 14 bungalows for a housing association. The external walls have a U Value of 0.19. The separating walls are 200mm thick concrete meeting sound regs for terraced housing. The walls are totally air tight and the completed homes are likely to achieve an air-tightness score of 1.8 or so. We have built a number of pool structures. The current project is to have twin walls. the outer walls will retain the ground and connect into the basement floor slab while the inner walls will be tiled and be the swimming pool itself. Some plant and services will be in the gap and corbel details will provide support for a floor to bridge that gap. In this Polarwall house, You will go in here through the front door, through glass doors in a glass wall directly into the pool. Reception rooms are on the floor above and bedrooms on the floor above. By using structural concrete and structural steel the client got large spans and long overhangs. Great economies are made where the basement footprint matches the house above doing away with all the usual foundations. Any windows and doors are easily incorporated. The well around them can be concrete to full depth or a shallow well.   An alternative means of escape (internally or externally) is required for basement bedrooms and very large basements as well. The floor over the top can easily be engineered timber or beam and block. Our current project will have a cast insitu floor incorporating beams and columns to span the swimming pool.
