Double Storey Extension in Queen's Park: what to know
Double Storey Extension projects in Queen's Park need to balance the homeowner's spatial ambitions with the practical constraints of the existing building and its setting. In NW6, where the housing stock includes victorian terraces and edwardian terraces, extension design must respond to plot depth, boundary distances, and the relationship with neighbouring properties. The typical delivery timeline of 16-24 weeks for construction reflects the technical complexity involved, but design and approvals add further months before building work begins. Getting the brief right at the outset — defining exactly what the extension needs to achieve and how it integrates with the rest of the house — is what separates projects that add genuine value from those that simply add square footage.
