As Executive Architect during the technical and construction stages, our role was to make the project even better. We exceeded the brief and obtained BREEAM Excellent in various ways including reducing the thickness of the Cross Laminated Timber structure that resulted in smaller foundations, changing the oil-based polyurethane insulation to a thicker mineral wool insulation with better thermal and fire performance but lower embodied energy, including more solar photovoltaic panels on the roof, and simplifying detailing of the building shell to increase construction speed and to improve quality control on site.
