Perforated Metal Facade and Natural Ventilation in a Sustainable Sloped Residence

Project in-detail

The use of perforated metal for sun shading and stone veneer cladding seamlessly integrates this sustainable residence with its sloping landscape, providing a balanced environment for family living.
5 key facts about this project
01
Utilizes perforated metal panels for effective sun shading and enhanced airflow.
02
Incorporates local stone veneer for aesthetic integration with the natural landscape.
03
Features a flexible open-plan layout that promotes interaction while maintaining privacy.
04
Designed for passive solar efficiency through strategic window placement and overhangs.
05
Integrates rainwater management systems as part of the overall sustainability strategy.

### Project Overview
The design occupies a sloped site, strategically positioned to relate to its natural environment while prioritizing sustainable living principles. The intent is to create a built form that connects both visually and physically with the terrain, enhancing the quality of spatial experience within the structure.

### Spatial Strategy
The building's three to four-story arrangement effectively utilizes the site's topography. The ground floor functions as the main entrance and communal gathering area, facilitating movement and providing sightlines to notable environmental features. The upper levels contain private living spaces, organized around an open-plan layout that encourages interaction while framing expansive views through large windows.

### Materiality and Environmental Considerations
The selection of materials emphasizes sustainability and aesthetic coherence with the surrounding landscape. Stone veneer provides a tactile contrast, while concrete block ensures structural durability with low maintenance needs. Wood is incorporated in roofing and framing to add warmth, and perforated metal elements offer sun shading while allowing for natural ventilation. A solar diagram illustrates the building's orientation, optimized for passive solar gain in winter and reduced exposure in summer, reflecting energy-efficient design strategies integrated throughout the project.
