Complete drawing set for our two-storey extension in Barnet. Planning and building-regs drawings done together, structural calcs coordinated with the engineer. £3,501 all in and the builder priced straight off the package. Saved a lot of back-and-forth on site.
Concept-to-completion design service for our Barnet home. Full service from first sketch through planning and building regs to site visits. £7,001 (around 11% of the build). The design got far more out of the space than we'd imagined and they handled every approval.
