The Hourglass Corral is a house located in the Cycladic island of Milos. It is also the most recent addition of “Voronoi’s corrals”, a project that began ten years ago and now encompasses a territory of about 90.000 m².
As a whole , the project has been an ongoing investigation of what it means to integrate the domestic scale using sustainable strategies into its rural landscape. The result has been the effective protection of wild natural areas, the reclaiming of the productive use of agricultural zones and the redefinition of the experience of leisure within the broad and complex environments.
The Hourglass Corral is the largest domestic environment of the property. Its organization is derived from the parametric manipulation of Voronoi Cells. Each cell corresponds to a clearly defined use, be it an exterior courtyard, a shading canopy, a common space, a bedroom or an auxiliary space. From the interior the ceiling of each cell folds upwards towards its center point where it is pierced by a circular skylight. The skylights are operable and together with the planted roofs, the exterior shading and the thick external walls they contribute to the reduction of the energy needs if the house.
Alike the other corrals, the Hourglass Corral has a stone fence that separates and protects from each other the wild and the agricultural areas. Inside, its cultivation is dedicated to Mediterranean plant species used for the extraction of essential oils. The cultivated cells encompass the entire corral, covering the roofs of the buildings and making the house volumes blend into its landscape. From above, the main clue of inhabilitation are from the circular skylights, while the difference between the planting areas reveal the cells: the underlining organization of the design.
Voronoi Cell Formation
The videos below shows a plexiglass box full of sand, with holes on the bottom. As the sand comes out, cones are formed, it is like an hourglass with many holes. The resulting shape on the surface of the sand is a Voronoi grid. The roofscape of the interiors in the Hourglass is like the sand. It is comprised of adjacent polygonic cones, with a circular hole at their apex.
The skylights at the apex open creating an effective passive ventilation system. A black out device is placed under each skylight. It is a mechanism that works like the shutter of a camera lens. For ambient illumination, a circular metal disc suspended under the apex conceals a linear light.
Yiorgis Yerolymbos is a photographer and architect. His work focuses on the interface of nature and culture as it can be exemplified in contemporary topography. We recently asked him to photograph ‘The Hourglass Corral’, the latest addition to Voronoi’s Corrals a larger territory of about 100,000m² on the island of Milos, where we have been working for the last ten years.
