Planning permission secured for residential reconfiguration in Primrose Hill
We are delighted to announce that we have achieved planning permission and conservation area consent from the London Borough of Camden for the modern reconfiguration of a historic property in Primrose Hill.
The property is a classic four-storey, mid-19th-century Victorian terrace building constructed between 1840 and 1870. Located in the heart of the commercial stretch of Primrose Hill, the building features a commercial unit on the ground floor with two distinct apartments arranged above. Unlike standard extensions that stretch out into a garden footprint, this scheme works entirely within the building’s existing envelope, focusing on an intelligent internal modernisation, window overhaul, and architectural upgrades to the rear elevation.
Working within the Primrose Hill places high demands on design and technical sensitivity. Camden’s local planning policies require any new interventions to strictly preserve or enhance the historic environment. Navigating this requires finding an absolute balance between client aspirations and strict municipal heritage guidance.
Our pre-application process highlighted exactly how rigorous the borough can be. Initial guidance from the Council noted that generic, slim-framed metal windows across the entire facade would cause a loss of historic character and create an incongruous appearance within the uniform terrace row. Taking that feedback on board, our team heavily revised the scheme into a far more contextually sensitive, hybrid design response.
To respect the historic rhythm of the streetscape while delivering the client’s goals for thermal efficiency and internal daylighting, we split our architectural approach:
Traditional Upper Facades: On the second-floor outrigger and third-floor stair landing, the outdated casements are being replaced by high-performance, double-glazed timber sash replicas that perfectly match the original style, location, and scale of the terrace.
Modern Interventions at Lower Levels: At the first-floor level (Flat 1), modern interventions are restricted to the closet wing. Here, an existing poor-quality PVC door is being replaced by a large, slimline powder-coated picture window and an adjacent glazed door leading down to the rear garden via new folded metal stairs.
This balanced approach – mixing high-quality modern glazing at the lower ground level with strictly traditional timber joinery on the upper floors – successfully demonstrated to Camden’s planning officers that the project will improve the building’s architectural quality without harming the wider conservation area.
The project is a collaboration between Pace Architecture and Sandra Flashman Studio, to create a stunning property. Sandra has worked closely with the client to refine the interior design and has allowed for an extremely precise and extensive interiors package. We look forward to working further on this project to achieve the dream home for our client.
