We take care of everything for you

We’ll provide top-class loft flooring, access hatches and doors for the eaves area, power points, halogen down light and radiators in each new bedroom. We’ll supply and fit the shower room plus tiling and also install Velux roof windows over the stairs. All walls and ceilings are finished with a smooth skim coat of plaster. 
We will complete our work to the highest standard, ready for you to apply your finishing colours and touches.

Bespoke loft staircases

With our bespoke staircases, we are able to offer plenty of options to fit whatever space you have. Our stairs are made from pine and we will always try to match them to your existing stairs. We can normally fit the new stairs over the existing stairs.
