Repurposing and extending a landmark historic building

Part refurbishment, part new build, this project was an interesting blend of the past and present and created a living and working destination within a once forgotten landmark.

This extensive refurbishment and new build project breathed fresh life into a collection of iconic Edwardian buildings.

The client wanted to maintain the existing building, but extend upwards. After detailed historical and structural investigation we were able to establish that although there was some wear and tear, the original structure, foundations and cast-iron columns were in good condition and could accommodate up to three more storeys.

Additional floors were constructed as braced steel frames, with decking at separation floors and to minimise the extra weight on the structure we fitted timber floors in duplex units. Large cantilever projections were designed as two-storey high trusses.

In terms of enriching the existing structure, we were able to add new façades with large full height glazing and sections of copper cladding. We also refreshed the existing facades by adding bolt-on balconies and full height slot windows. To complete the job with a high-end finish we repaired and strengthened the masonry piers and the filler joist floors.
