Harpenden

A stunning family home in one of Harpenden’s most sought-after streets is being transformed from within — delivering an extraordinary 220 square metres of living space beneath an already much-loved property.

With no desire to uproot their family, our clients’ brief was clear — rather than move, they wanted to unlock the hidden potential lying beneath their feet and create something truly spectacular.

We are currently retrofitting a substantial basement beneath the existing property, carefully engineering a lower ground floor that redefines what it means to live well. The scale of the project has allowed us to create a space of remarkable variety and ambition — a professional music studio, a cinema room, a wine store, a guest bedroom, a library, a games room and generous storage, all anchored by the jewel in the crown — a stunning swimming and spa pool.

When complete, our clients will have a home that not only meets every need of modern family life, but exceeds it — a private sanctuary beneath their feet that rivals anything the open market could offer, in the street and community they have always called home.
