Why You Should Consider Basement Construction in Twickenham
With building up being actively discouraged in many places around the capital, building down has become a popular alternative. If you plan to modify an existing basement, the project is likely to be allowed under permitted development. Also, building down does not alter the appearance of your home in a fundamental way. And if you want to create or expand a basement, you can add multiple rooms serving different lifestyle functions (though planning permission will be required if digging is involved).
Enhancing Your Home’s Liveability and Value
A finished basement from Room Below will provide your home with a significant boost in liveability while also boosting its market value. Depending on the size and extent of the basement build, that jump in market value could be very substantial. So don’t wait around hoping that someday your plans to build out or up will be approved. Instead, call Room Below and begin the process of gaining the space you want and need.
