Lizzie Webster and Joe Fraher, founders of Fraher Architects, carried out a comprehensive modernisation of Signal House, a Victorian property in central London.
By introducing a new staircase that ascends through the centre of the house, the architects have created an enhanced connection and better cohesion across all floors of the building.

"The client asked us to look at revisiting every aspect of the existing building to propose the most efficient use of space whilst creating a strong sense of place within each of the floors," said the architects.
