Mexican architect Tatiana Bilbao explains how her concrete Casa Ventura house responds to the topography of its hilltop site in the next instalment of Dezeen's Concrete Icons series produced in collaboration with Holcim.

The video features Casa Ventura, a large family home that emerges from a forested hillside overlooking the city of Monterrey, Mexico.

Speaking to Dezeen in an exclusive video interview filmed at Bilbao's office in Mexico City, the architect explained how the house was designed to "flow horizontally" and be "really open, very fluid".

"What we did was kind of break the volumes of the house," Bilbao said. "Every volume is connected to the next one, with very few steps."
Completed in 2011, the residence comprises a series of connecting pentagonal volumes that sit atop a steeply sloping hill with an uneven topography.
