We are providing structural engineering for the offsite modular timber design of 215 zero-carbon council homes across 4 sites for the Royal Borough of Greenwich. This is part of the “Greenwich Builds” programme: a wider appointment for Ideal Modular Homes to provide 500 affordable homes in the borough that exceed carbon zero standards and reduce fuel poverty. Ideal’s modular homes take four days to be manufactured and eight hours to set up on site. The first of these homes for council tenants were assembled early 2021.
The first development includes the Sam Manners and Well Hall Road sites, comprising 45 apartments and 8 townhouses. Other developments, including the Brooks sites & Orangery Lane, are running in parallel and comprise a total of 43 apartments, 90 three storey townhouses and 29 two storey houses; allowing for efficiencies in design of standard housing units in different configurations and storey heights.
The modules are designed to promote energy efficient living and incorporate solar panels and MVHR systems into all standard housing and apartment units. Additionally, each development is delivered utilising modern, sustainable construction methods and comprise engineered timber elements, packaged in volumetric modules securely fitted on site. Each module is comprehensively constructed and finished in the factory – including application of structural sheathing, externally applied fixings, electrics, plumbing and glazing – minimising time spent on site by follow on trades.
Our role in the project is to design and optimise the timber systems and maintain robust stability strategies, in addition to establishing the limitations of the new standard Ideal modules as they develop. We liaise directly with the Ideal fabrication and assembly teams to provide comprehensive timber frame designs for each unit, incorporating the characteristics of offsite volumetric modular construction to minimise site-based activities and methods. We also provide BIM services in co-ordinating architectural and fabrication models prior to receipt of factory drawings for approval.
