Two Storey Extensions
in Beckenham

A two storey extension is the ultimate way to maximise additional living space in your Beckenham home. By building upwards as well as outwards, you gain significantly more floor area than a single-storey extension — typically adding both a spacious kitchen-diner on the ground floor and an additional bedroom with en-suite above.

Grand Innovations delivers premium two storey extensions across London that are architecturally sympathetic to the existing property. We use precision material matching, careful roofline engineering, and high-quality glazing to ensure your extension in Beckenham feels like it was always part of the original design.

Two storey extensions in Beckenham typically require full planning permission from London Borough of Bromley. Grand Innovations manages the entire planning process, from preparing detailed architectural drawings through to securing approval. We also handle all structural engineering, building control applications, and party wall agreements.

With our transparent weekly billing model, you maintain complete financial control throughout your Beckenham project. No large deposits, no staged payments tied to uncertain timelines — just fair, honest payment for completed, inspected work each week.
