Timber Development UK, working with Waugh Thistleton Architects, has released Timber Typologies, a free downloadable ‘beginner’s guide’ for various timber solutions. Fran Williams speaks to Waugh Thistleton associate Alastair Ogle to find out what it’s all about.  …Providing these typologies and typical use cases demonstrates how timber can be used for the majority of UK construction. When timber is not considered, higher-carbon and non-renewable materials such as steel and concrete are used instead, which can significantly increase the embodied carbon of a project – by up to 75 per cent. …We know that over 90 per cent of concrete used in the construction industry could easily be replaced with timber and so we hope that this will push that agenda. …Given that we pioneered the use of mass timber in mid-rise development in the UK, it is a travesty that we are no longer the world leaders in using it.
