The terrace just had boring concrete slabs covering the area so we subsequently replaced these with a substantial framework supported on adjustable pedestals to accommodate the undulating slab beneath. We surfaced it with ThermoWood Ash Hardwood decking using our Invizifix hidden clip system with end jointing boards. The picture frame and infill under the benches and around the planters are in Iroko to match the bench slats. Once the planting out has been completed the overall effect provides a more relaxed and better working environment.
