New Off-Site House Range Hits The Streets

UK off-site timber frame manufacturer Donaldson Timber Systems (DTS) have launched a range of timber-frame house types.


A range of key housing types

The 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.

They are the product of consultation with architects, planning consultants and a leading UK housebuilder: they ensure the houses meet regulatory housing requirements across the UK.

Uniformity with flexibility

Each home incorporates individual design flexibility to allow for changes like 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.

However, the specified components are also consistent, using a limited range of window sizes, with uniform bathroom and WC setting-out to ensure the efficient procurement of materials.

A prefabricated timber system

Using DTS’ Sigma II closed panel timber frame system, the house range provides long-term energy efficiency, and exceeds Homes England’s minimum requirement for a Pre-Manufactured Value (PMV) of 55%. The frames can be windproof and watertight on site in one day.

The homes are also land efficient, and a consistent depth of floorplan allows different house types to be simply built as terraced blocks. The house range is supported by a suite of architectural design information with Level 1 BIM models.

DTS is developing further supporting information, including SAP calculations, specifications, schedules and build costs for the full house range. This info will, according to DTS, vastly reduce the lead-times and up-front costs associated with developing a range of house types from scratch.
