Our experienced and skilled team can turn that wasted space into exceptional living spaces, whether it is a bedroom, study or extra living room. There are endless options when it comes to loft and attic conversions and with the help of William Sedgewick Developments Ltd, you can put your loft to better use, instead of just having it as a storage facility.

Adding an extra room to your home can also add value to the property, so do not miss out on the chance to improve your home, create extra space and potentially increase the rewards if you do choose to sell your house at some point.

While our loft and attic conversions are incredibly popular, we also provide a basement conversion service. Like the loft space, basements are a great way of creating an extra living space and can provide a great opportunity to have an office, playroom for the children or a studio.

Not only will our conversions increase the value of your home, they will also save you money by allowing you to stay in your home and not face the hassle and expense of moving to a larger house. In these recession hit times, this could be absolutely vital.


We were very impressed with the service that we received from Chris when we had our extension built.

We have been extremely impressed with Chris and his team throughout the whole process and would both recommend the company to others

Just to say we are really really pleased with the floor - it looks great and is such a massive improvement on what was there!
