Reedham House


Creating a net zero carbon in operation office building in a conservation area.

Ambitious plans to redevelop Reedham House will create a modern, flagship office building in the St Mary’s Parsonage Strategic Regeneration Framework (SRF) area.

The vision for the SRF is to develop this currently underused area into a thriving and sustainable neighbourhood which maintains a distinctive character. The site also sits within the Parsonage Gardens Conservation Area based on the square of the same name – a tranquil urban garden surrounded by a mix of distinctive architecture.

The re-development of Reedham House will create a new 13-storey office building with retail units on the ground floor, helping to open up this block to the surrounding area. The historic carriage works building will also be refurbished and incorporated into three new floors of office space. With sustainability at its core, the development will be net zero carbon in operation and achieve an EPC A rating.

Designed to reflect and enhance the character of the area, which contains a number of listed buildings, Reedham House will drive the development of this vibrant and sustainable new neighbourhood.

Crookes Walker carried out enhanced performance design for the M&E services to support the planning application. A dynamic building model was used to carry out an energy performance appraisal, evaluating the building’s performance against the UK Green Building Council framework 2050 “Paris Proof Target”.

A life cycle assessment was also carried out to evaluate the environmental impact of various methods and materials, with a target of net zero embodied carbon in construction.

The project received planning approval in July 2023.
