In our Dartmouth Park project the concrete beams at roof level create a horizontal datum across the spaces. This begins internally and continues outside to shelter the barbecue area, finally returning to the ground to form a new pergola against the garden wall. When viewed from the garden, this continuous horizontal line creates the impression of a unified, wide extension that emphasises the generous 17m garden width.
The structural beams in the extension are concrete with GGBS to reduce cement content. Underfloor heating, energy efficient appliances and low energy LED lighting were specified throughout.
