The design of the “Finally a Court House” by Spacecraft Architects is centered around the concept of a courtyard, influenced by Wellington’s constant wind patterns and the desire to provide sheltered outdoor space. The house features a blank exterior with high insulation, except for the north-facing wall which allows winter sun to pass through onto an insulated concrete slab, facilitating passive solar heating. All rooms within the house open up to the central courtyard, offering ample daylight and natural ventilation.
Sustainable Construction and Thermal Efficiency
Constructed on a thermally broken natural concrete slab, the house employs thicker wall framing to enhance thermal insulation. Exterior walls are clad in economical and fireproof fiber-cement sheets, while the walls facing the courtyard are adorned with locally sourced untreated Heart Macrocarpa. Corrugated polycarbonate sheets serve as exterior screens/roof, shielding the courtyard from wind while permitting sunlight into the garden.
Energy-Efficient Features
Windows throughout the house are powder-coated aluminum with clear double-glazed units, strategically oriented north and west to harness winter sunlight for warmth. Natural ventilation is facilitated by large doors opening onto the courtyard, eliminating the need for artificial cooling. Additionally, a skylight in the bathroom allows for easy ventilation and steam removal.
Winter Comfort and Heating Solutions
During winter, the living room and bedroom concrete slabs benefit from direct sunlight, effectively captured by the high levels of insulation. A small combustion wood fireplace in the living room serves as both a heater and stove, contributing to the cozy ambiance. Hot water is supplied by an instant gas system located within close proximity to plumbing fixtures, ensuring efficiency.
Lighting and Sustainability Measures
The house features low-energy LED lighting with ceramic light shades designed by the architects, promoting sustainability and energy efficiency throughout the space. This conscious approach to lighting design further enhances the eco-friendly features of the “Finally a Court House.”
In essence, Spacecraft Architects have succeeded in creating a sustainable and energy-efficient residential space that seamlessly integrates with its natural surroundings, offering comfort and functionality while minimizing environmental impact.
