Pear Tree Street

Pear Tree Street

The development at 41 Peartree Street in London saw the construction of a fifth floor penthouse apartment on an existing residential block. Ayesa were appointed to undertake a feasibility study to check the structural capacity of the existing building. The design of the new apartment incorporated a proprietary timber panel system supported on a steel grillage to transfer the loads to the columns of the existing structure.

Pear Tree Street


To prove the capacity of the existing building, Ayesa were able to utilise enhanced column capacity by employing the age related strength gain of the concrete and to demonstrate that the basement slab was able to add to the pile capacity by raft action. Ayesa also helped develop a construction sequence which would minimise the construction impact on the existing tenants, a significant concern for the client. This design saw the timber shell of the structure fabricated off site and then set in place before the lift shaft and stair core were extended into the new apartment.


And again...

Ayesa were also involved in similar projects for the same client at a near by block on Seward Street and an adjacent block on Pear Tree St in London. These comprise five further apartments providing some 5000sq. ft of living space along with roof terraces giving spectacular views across the City.
