Office S&M specialise in infill housing on small sites. As leaders in this field, we have input on the development of Croydon’s small sites policy, which our project Valetta House is featured as an exemplar in; then workshopped Tower Hamlets’ small sites policy, which our project Salmen House is featured as an exemplar in; and most recently commented on the Lewisham small sites policy during two workshops. More recently, we have reflected on the published small sites policy in the London Plan, run Clubhouse and Podcast discussions about delivery on small sites, and presented to Urban Design London as experts in this area.


The detailing of our proposal has been developed from an investigation into the laying patterns for hung fibre cement tiles, with the aim of breaking up the mass of the building. The tapering corners and diminishing tiling creates a forced perspective that aims to make the building appear further away than it actually is. This careful detailing elevates an affordable material to a high quality finish, while also making a cohesive whole of building form.



We believe in a renewed purpose for backland brownfield sites, which we investigate in all of our small site work. All of the proposed units are dual aspect, and have generous private amenity, as well as a communal garden and play area at the front of the building. The proposal contains two three bedroom units on the ground floor with generous front and back gardens, and direct access from the road, with three one beds and a two bed on the first and second floors, and finally two studio units, but with separate kitchen and dining rooms, occupy the third floor. The barrel-vaulted roof achieves the most internal headroom with the least impact on neighbours, and the design makes use of the stepped section of the site - which was a former gravel pit - in order to maximise the size of the ground floor units.
