The range of 18 core house types includes cottage flats with a mix of one and two bedrooms; semi-detached and detached two-bed bungalows; and a selection of detached, semi-detached, and terraced homes of two, three and four bedrooms.
DTS worked closely with experienced architects and planning consultants and designed the range in conjunction with a leading UK housebuilder to ensure the house types met regulatory housing needs across the UK.
The homes are designed to maximise the benefits of Design for Manufacture of DTS’ Sigma II closed panel timber frame system, as well as the site installation for both the superstructure and all follow-on trades. The specified components are also consistent, using a limited range of window sizes and uniform bathroom and WC setting-out to ensure the efficient procurement of materials from a variety of manufacturers.
Each home also incorporates individual design flexibility to allow for changes such as the addition of showers in ground floors; built-in wardrobes; additional kitchen storage; and space for air source heat pump hot water cylinders, so they are future-proofed for simple adaptions to suit lifestyle changes or improved energy efficiency.
Utilising DTS’ Sigma II closed panel timber frame system, the house range provides long-term energy efficiency; meets and exceeds Homes England’s minimum requirement for a Pre-Manufactured Value (PMV) of 55% using only the timber frame build system; and allows the frames to be windproof and watertight on site in one day. The homes are also land-efficient, with the width of each floorplan reduced to ensure roads, footpaths and services are minimised, and a consistent depth of floorplan allows different house types to be simply built as terraced blocks.
“We are working closely with the wider housing sector to drive continued quality and performance standards, and our new house range provides both to the market,” said John Smith, technical director at DTS. “We conducted extensive research in the sector across the UK to understand the needs of residents, developers, planners, and all relevant regulations, and these house types provide homes that are designed to offer maximum flexibility while meeting all space standards in the most efficient way possible.
“Sustainability and efficiency are also key to the sector, both for speed of build and longer-term performance for residents. Our timber frame system’s fabric-first approach comes with embodied carbon calculations and PMV assessment for each house type, to ensure sustainable, resilient, and affordable homes that efficiently meet the current build regulations and can be easily and simply updated to achieve the requirements of the Future Homes Standard.”
The house range is supported by a suite of architectural design information with Level 1 BIM models. DTS is also developing further supporting information, including SAP calcs, specifications, schedules and build costs for the full house range. Having this information in place will not only allow customers to reap the benefits of the efficiency of the house types, but vastly reduce the lead-times and up-front costs associated with developing a range of house types from scratch.
