Energy efficient offices on a low-grade commercial strip at the edge of Grantham

Designed to house a staff of 200 people, the project aims to create a highly innovative and sustainable building within a market rate budget, and to achieve a BREEAM Excellent rating.

The client sought an inspirational place to work, which will demonstrate an innovative response to the current and future operational needs of the organisation, in the hope the building would strengthen the Trust's cultural values and reflect well on the charity.

Cross laminated timber construction, painted on the inside with a specially developed white varnish, was used throughout this 2,728m2 building. Meaning that timber acts as a moisture resistant membrane, while concrete panels were fixed to the frame structure to provide thermal mass with the minimum embodied carbon possible.

Office floorplates have a void for good daylight and natural ventilation with direct sunlight filtering through solar controlled glass providing bright, uplifting areas.
