The French duo of Anne Lacaton and Jean-Philippe Vassal are known for their delicate interventions, repurposing neglected structures with apparent effortlessness. Originally published on the Harvard Gazette website entitled "They Build, But Modestly," this article recounts the lessons which they offered students in a recent lecture at the Harvard Graduate School of Design.

Around 1980, two young architects finished their training in Bordeaux, France, and moved to Nigeria. In that African nation’s remote regions, they were inspired by the simple structures they saw amid the stark, stunning desert landscapes. The houses were open to the air, had utilitarian thatched roofs, and were made with bits of local wood. Modesty prevailed in structures that also invited beauty.

The lessons of building in Africa stayed with Anne Lacaton and Jean-Philippe Vassal in their Paris-based practice, Lacaton & Vassal: use what is there, stay simple, embrace open air, and honor light, freedom, and grace. They practice social architecture based on economy, modesty, and the found beauty of environments.

It may be the world's second oldest construction material, but wood is still one of the most versatile and inspiring materials available to architects today, coveted as both a structural material and as a finish on walls, floors, ceilings and facades. In recent years it's even seen a resurgence in popularity, thanks to its sustainability credentials and its increasingly popular "natural" feel. With all this in mind, ArchDaily Materials has rounded up five recent projects that prove innovation in wood is still alive and well in the architectural world: Wilkinson Eyre Architects' Maggie’s Oxford; Shigeru Ban's Aspen Art Museum; Pushed Slab by MVRDV; MARGEN-LAB's Endesa World Fab Condenser; and finally a forthcoming building that is notable for its ambitious wooden design, the Sleuk Rith Institute by Zaha Hadid Architects.
