Tigh Grian Ltd was set up to provide cost-effective quality housing for mainstream homes, hostels, and other accommodations.

Each house comprises of volumetric units with dimensions 4.9m by 9.9m and can be built as single storey or up to 4 storeys, in number of configurations.

The volumetric units arrived on site ready to be lifted onto pre-prepared foundations and service connections. The lifting bolt for each unit acts as an additional robust link for improved structural soundness. The two houses were assembled in 6 hours and were watertight at the end of the process.
