Grampian Oaks House
Nelson

This home was designed as a personal project by DBA director Peter Marment. It was designed with his family in mind and driven by the desire to balance design quality, energy efficiency, sustainability, health, and affordability.

Energy Efficiency & Sustainability

  • Passive solar design maximises winter warmth and keeps interiors cool in summer.

  • Enhanced insulation and airtight construction reduce heat loss.

  • LED lighting and WELS-rated taps (3-star+) save energy and water.

  • Pre-plumbed for rainwater reuse for toilets, washing machines, and garden taps.

  • Locally sourced NZ timber used for structure, cladding, and decking.


Affordability

  • Simple house forms and rooflines reduce construction complexity.

  • Low-cost, locally available materials provide value.

  • Efficient, well-planned spaces prioritise function over unnecessary size.

HomeStar Rated

  • Achieved HomeStar 7 with PV panels and rainwater collection.

  • Verified by the NZ Green Building Council for performance and sustainability.

Health & Wellbeing

  • A balanced heat recovery ventilation system ensures healthy indoor air quality.

  • Low-VOC paints and formaldehyde-free plywood joinery create a non-toxic environment.
