What is it?

Maggie’s Oldham, UK, is the world’s first building made from
hardwood cross-laminated timber (CLT). Located at specialist NHS cancer
hospitals and designed to be welcoming, Maggie’s Centres provide professional
support to people living with cancer.

Who is involved?

UK-based company, dRMM Architects, designed Maggie’s Oldham,
while CLT specialists, Züblin Timber, Germany, developed the structural
CLT panels.

What materials are
involved?

CLT is a prefabricated wood panel, consisting of several
sheets of timber layered in alternating directions to increase strength. The
27.6m3 of American tulipwood and 1.1m3 of American ash
that make up Maggie’s is equivalent to 55.22m3 and 2.1m3
respectively of sawn wood prior to processing.

How is it novel?

Tulipwood is the fourth most abundant timber in US hardwood
forests. With the speed of growth greater than the level of harvesting, it is
also under-exploited. It is fast-growing, naturally reseeds and is a carbon
store.
