Architecture studio MAPAA has created a barrel-vaulted concrete office for a family-run wine business based in Pirque, Chile.
MAPAA used pigmented concrete to create a trio of arching vaults over the offices, which are raised on trusses to sit against the sloping site.
The offices look out over the vineyard
Built for the Viña Haras de Pirque vineyard in the Maipo River valley at the foot of the Andes mountains, the form takes cues from traditional cellars found in the area.
"The barrel vaults reference the ancient underground cellars used for the storage of wine, characteristic of the winemaking tradition of the central area of our country," MAPAA co-founder Cristián Larraín told Dezeen.
Three concrete vaults top the offices
Wooden formwork and a series of trusses were used to create the archways, which frames a wall of glazing looking out over the vineyards and an olive grove.  A wide balcony runs along the front of the offices. The board-marked concrete walls have been left bare in the interiors, contrasting with ceramic floors and doors and furniture made of wood.

This area is oriented around a huge Italian tapestry belonging to the vineyard's owners, which separates a smaller reception area and a larger meeting area.
