Multi-Generational & Shared Site Design

Affordable | Efficient | Community-minded living

2–3 households on a co-developed site — creating warm, healthy homes at a fraction of the cost of buying separately.

These homes are designed to be compact, not cramped.

By reducing wasted space (hallways, oversized rooms, unused corners), we create homes that are smaller in footprint but generous where it matters — light-filled living spaces, practical storage, and comfortable bedrooms.

Example 1: 3 Homes

  • 3-bedroom two level home

  • 2-bedroom two level home

  • 1-bedroom single level home

  • Shared driveway + outdoor space

Who This Suits:

  • Multigenerational whanau who want to stay close while enjoying independent space

  • Families helping adult kids to buy

  • Ideal for families with young kids 190m² outdoor garden space (plus parking spaces)

Floor Areas

  • 1-bedroom: 46m²

  • 2-bedroom: 78.5m²

  • 3-bedroom: 104m²

TOTAL FLOOR AREA: 228.5m²

Indicative build cost (per dwelling)

  • 1-bed (46m²) → ≈ $185,000

  • 2-bed (78.5m²) → ≈ $310.000

  • 3-bed (104m²) → ≈ $420.000

Indicative build costs are based on an assumed construction rate of $3,500 per m² + GST, calculated by multiplying the home’s floor area by this rate. They do not include site costs & outdoor areas

These example layouts are intended for sites of approximately 400m² or larger.

Site suitability will depend on planning rules, site shape, access, and local council requirements
