Whether you are digging below ground to introduce a new room, extending a space you already have or renovating an old cellar, basement rooms are proving increasingly popular — particularly in built-up areas where there’s little opportunity to add a ear or side extension.

From media rooms to study spaces, playrooms, studios and more, we list some of the best examples of basement projects to leave you feeling inspired.

A Modern Home Office

A Basement Cinema

A glazed balustrade to the staircase offers light and a sense of space to this long lower ground kitchen diner in London. A cosy atmosphere is created through careful ambient lighting while bifold doors open out onto a sunken courtyard.

A Traditional Cellar

A full 4m deep cellar was dug beneath this Georgian-style new build property to offer storage space, work and utility rooms, along with extra-deep structural footings. The curved brick design creates the look of traditional cellars in old stately homes.
