This project required the construction of a basement in order to create a two-story ‘Granny Flat’. Initial works included fully supporting the existing detached residential property, then excavation with full temporary works propping. Difficult access presented an additional challenge for soil removal. Major structural support was required throughout as all sections of the new ‘floor’ were located in the main support walls of the existing property. Fit-out included completely new services throughout including underfloor heating. The addition of a bespoke balcony (where the original rear door had been!) added a finishing touch to the project.
