A four unit apartment block in an in-fill site. Built using the Thin-Joint method and Jumbo Bloks.

The developer used H+H’s Thin Joint system of large format aircrete blocks and quick-drying Celfix Mortar to achieve Level 4 requirements of Code for Sustainable Homes for a four-apartment development on a confined site in Brighton.

This was the first time the contractor had used the H+H Thin Joint system for external wall construction, although Canning Ericsson had used H+H’s Jumbo Bloks for the construction of internal partitions on previous developments.

The Thin Joint system also worked well with the limited storage available on this tight site, which has been slotted into the end of the back garden of an existing home. Because of the restricted site storage, just-in-time deliveries of blocks were made by PBS, a local H+H Aircrete stocking merchant.

In addition to the scheme’s highly insulated building fabric and as part of the planning requirement photovoltaic panels were used to generate electricity from the sun on the roof of the project. This ensured one apartment achieved an EPC A rating on one apartment, with the remainder of the development achieving a B-rating.
