The opening of the world’s largest modular homes construction site in Sherburn-in-Elmet goes to prove that “flat-pack buildings are no longer just for summer houses or garden sheds,” notes Donaldson. “Prefabricated timber walls offer a fast, cheap and clean way to build housing and we are already seeing an increase of this in the UK.” Goodfellow agrees and believes the advantages of timber are only truly realised when paired with offsite construction and manufactured into precision engineered timber systems. Stewart Milne Timber Systems has the capacity to produce more than 10,000 units per year at its Aberdeen and Witney factories and with less reliance on trade skills and onsite supervision, build times can be much faster than traditional building methods. “We can offer call-offs from as little as three weeks and once onsite, a typical four-bedroom detached home can be erected, wind protected and made watertight in as little as five days,” says Goodfellow. One firm who can do even better than that is Robertson Timber Engineering, who Redwell Primary School: Two schools become one Acting as the main contractor Robertson, in partnership with Clackmannanshire Council, combined the St John’s and Claremont primary schools in West Alloa into one purpose-built facility. Designed by architect Keppie Design, the £8.1 million project, which was completed in August 2014, was delivered through the hub East Central Scotland framework. The primary structural frame is timber, with the exception of the two-storey steel-framed games hall. The external finishes are a mixture of facing brick, render, curtain walling and cladding. Robertson Timber Engineering manufactured, supplied and erected the school’s timber frame in partnership with Robertson Central. One of the challenges was integrating the new timber frame with a traditional steel frame structure, as well as ensuring air tightness requirements were met. For the latter, Robertson Timber Engineering worked with BSRIA to integrate the vapour control layer within the timber frame. The use of factoryinsulated, prefabricated roof cassettes saved considerable time on site. Traditionally trussed areas were constructed on the ground and then lifted into place, which meant operatives were not working at height and in turn sped up the process. Both of these solutions reduced the need for expensive fall-arrest systems and provided a safer working environment for site operatives. n alongside Robertson Partnership Homes, is currently building a “house in a day” as part of a £12 million housing development for Fife Council. The affordable Methil Brae homes, which include semidetached units, bungalows and cottage flats, are being built using timber frames manufactured offsite. The panels are produced in a controlled factory environment, reducing wastage of materials and ensuring production of a quality product ready to be used in the construction process. “From erecting a timber kit onsite and putting the ground floor wood panels in to creating the first floors, upstairs wall panels and putting the roof on, we can build a standard threebedroom home in a day,” says Barry Ranum, sales director at Robertson Timber Engineering. Originally set up as a joinery business in the mid-1980s manufacturing timber doors and windows, Robertson Timber Engineering quickly moved into producing timber housing kits and the company is now one of the largest timber-frame Travelodge Oxford
