Andrew Waugh is an architect with a passion for using sustainable materials in construction projects. His practice, Waugh Thistleton Architects, is a London based architectural practice producing thoughtful and sustainable projects both locally and internationally.
The practice is a world leader in engineered timber and pioneer in the field of tall timber buildings. Of particular renown is the Black & White building in London that has been short listed for a RIBA London Award in 2024. The build was described by RIBA journal as 'a major step forward for the development and construction industry’ and is the tallest engineered timber office building in central London.

In 2023, Waugh Thistleton were named Architect of the Year in AJ Architecture Awards 2023. The Architect's Journal recognised the practise for their long standing advocacy for timber saying that 'In the face of the climate crisis, Waugh Thistleton is a worthy winner for its ability to work within the constraints of very challenging policy yet create cutting-edge, sustainable architecture. Not only that, it is also prompting the whole industry to raise its game.’

In this podcast, Andrew explains the different types of engineered timber and how some have superior structural strength while others have the mass required to offer superior acoustic performance. The choice of materials, as he outlines, is determined by usefulness, cost and how they fit into an overall objective of using as few materials as possible.
Andrew’s passion for the use of sustainable materials shines through as he explains how the wood used is sourced from forests planted with biodiversity in mind. The forests are not monoculture forests, they are planted with FSC of PEFC licences, and the harvest used for producing construction materials is a long way short of the overall capacity of the forests to produce sustainable timber.
From a biophilic design perspective, Andew details some of the many health and well-being benefits of using wood in the built environment. The better acoustics, the hydroscopic nature of wood creating better air quality and the calming properties of sawn timber are among the benefits discussed. He also describes how the external wood design, creates Solar shading on the building which reduces energy use for heating and cooling by about a third.
Talking of the Black and White building, Andrew says:
“IIt is important for us to ensure that this move towards low carbon construction, low carbon architecture is not a peripheral occupation. It is not just for birdwatching centres, and National Trust museums, it has to be mainstream. The entire building, which was built for a commercial company, Blackstone, is above the ground floor slab made of timber. So, it's timber staircases, timber, lift shafts, timber beams, columns, floor slabs, external wall curtain walling is timber, and the external cladding is timber as well. A completely timber building. It was built very quickly in 83 weeks. So very fast construction. It was cost equivalent to concrete. We were obliged to track the cost of the building all the way to tender with the main contractor against a concrete equivalent building and we were able to demonstrate that it was cost equivalent.

So fast, inexpensive, and letting extremely well - the client’s very happy, which is really nice.”
Each piece of timber has a QR code, so it can be placed exactly into place. So it’s not only fast but also quiet and clean. Put that against the usual cement trucks and building site cacophony. In fact the whole building took only 70 deliveries
The overriding message from Andrew’s advocacy of sustainable building, using the example of the Black and White building, is that using these technologies and approaches is a positive advance in construction with myriad benefits. It is no longer necessary to wear a metaphorical hair shirt to build in a way that is sympathetic to the environment. Fast, quiet and quick construction of modern buildings filled with biophilic design is the route to happy owners and happy occupants.
