One Portwall Square is a new-build office for independent developer Nord on a site close to Bristol Temple Meads railway station. The site was originally part of 100 Temple Street, a large office building designed by John Wells-Thorpe during the 1970s including a raised squash court with parking below.

The new-build scheme replaces the disused squash court with a six storey freestanding office building, set back from Portwall Lane to create a lively pocket square at ground level. The proximity to 100 Temple Street has been a key consideration in the building’s design, reflected in the high floor to floor levels which match those of its neighbour. The design uses a low spandrel that wraps around the building, forming the balustrade to the cantilevered south-facing terraces at each level and shading the storey below. A complementary palette of materials has been selected for the façade taking its cue from the neighbouring orange-red brick and pre-cast concrete buildings. Occupant comfort is at the forefront of the design, using energy efficient systems including smart ventilation and in-slab cooling.

In December 2022 One Portwall Square became the new base for the AHMM Bristol office, with the practice letting the ground and first floor of the building. The new space is double that of the previous studio, allowing the team to expand and providing new facilities.
