# Orange Tonal Concrete Homes Álvaro Siza Designs the Colien House on a Sloped Site in Spain By Amy Duong | Published 2024-10-07 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/colien-house References: [dezeen](https://www.dezeen.com/2024/10/03/colien-house-alvaro-siza-barcelona/) & [alvaroleitesiza](https://www.alvaroleitesiza.com/)  Portuguese architect Álvaro Siza finishes the design of the Colien House overlooking a beach in Barcelona. It is defined by its orange-tinted structure which is made from exposed concrete. Álvaro Siza creates each floor in the house to have an outdoor terrace continuing to the internal spaces as well -- this way, it connects the [sloped terrain with the sea nearby](https://www.trendhunter.com/trends/house-in-three-heights). Siza shares with Dezeen, "The central purpose was to answer the programme proposal made by the client by including a careful embodiment of the landscape, complying with the specific local rules and the relation of each of the four floors' elevation with the natural topography. Each house level offers a terrace that amplifies the interior space, while relishing the landscape's natural beauty and the 180-degree view from east to west."
