TSA’s ethos is rooted in a human-orientated approach to adaptability through the use of narratives in time focused on the inhabitation and experiential qualities of architecture.  Their proposal is for a brick extension of a staircase at the rear of a Georgian building in Soho, London.  The proposal creates a wider circulation path as well as promotes qualities of the converted spaces (commercial & residential) as you move up and down the building builds respecting the adaptable Georgian structure for its simplicity in overall arrangements, intricacies of details, careful composition of proportions and hierarchy of spatial organization.  The proposal focuses on the building fabric and the use of the openings as apertures for light, views and air.  The apertures shift and change over time to reflect both shifts in the internal functions and the changing physical and cultural surroundings of Soho.
