Basement conversion – mid terraced house

The property in question is a 7-bedroom, mid-terraced property, close to the centre of Lytham St Annes in Lancashire. The damp, musty cellar was virtually unused, except for storage.

The owners wanted to use the cellar to create an additional living-space, accessible from the ground floor. The main requirement was for an adults ‘chill-out’ room with an adjacent wet room and sauna.

The basement conversion (interior works)

The cellar conversion project was carried out following a recommendation from the owners of another successful cellar conversion project in Lytham.

The floor of the cellar was damp and uneven. It was, therefore, excavated to provide a level base, with additional material removed to increase head-height. A new floor slab was then laid, incorporating Aquadrain Drainage Channel around its perimeter, leading to a sump and pump.

Oldroyd Xv Clear Cavity Drainage Membrane was fixed to the cellar walls using special Oldroyd fixing plugs. The same membrane was also laid across the cellar floor, ensuring an overlap with the membrane already fixed to the walls.

A screed was then poured onto the Oldroyd Xv Membrane on the floor. Wiring and plumbing were then installed, before being covered by plasterboard attached to the Oldroyd fixing plugs on the walls.

Interior design

Having provided a dry basement, further works were carried out to provide a useable basement space, to the client’s specification. The heart of the new space is a home cinema with a flush-mounted plasma screen and surround sound system. The under stairs area houses a bespoke sauna that was hand-built on site. The wet room incorporates a WC with macerator and a drain, set into the newly tiled floor.

The basement conversion (exterior works)

To provide additional light and direct access from the outside of the building, the existing wooden door, leading to the basement, was replaced with a glass door. On the other side of the building, earth below a small basement window was excavated and a wall ‘knocked through’ to provide a lightwell/second entrance.
