MODULHAUS™ offers a sustainable and cost-effective solution to growing temporary accommodation needs across many public and third sector needs. Utilising offsite methods and volumetric modular technology, 
MODULHAUS™homes are robust, reliable, and relocatable over a 60-year design life.

The Volumetric Modular Ltd. Modulhaus system

The modular system comprises a galvanized steel structural framework which is infilled internally with floor, wall, ceiling components to provide thermal, acoustic and fire resisting performance; externally wall cladding and roof covering provide weather resistance. Each unit is designed as an individual home.

Space heating and hot water is supplied from a central source (excluded from the BOPAS assessment).

Module configurations include: single storey or stacked two storey detached or terraced blocks. Thestructural components have an estimated service life of 60 years. The modules are assumed to be used astemporary accommodation with planning permission for 5 years to a maximum of 15 years. The modules will be relocated within 15 years. The dwellings are manufactured by Volumetric Modular Ltd. Stafford Park 10, Telford TF3 3B and 101 Longden Road, Shrewsbury, Shropshire, SY3 9PS assembly facilities.
