Grassmere Downs

Horncastle Homes

East Rangiora, Canterbury, New Zealand

This six-stage development of 225 residential lots with a total site area of 32ha is part of the East Rangiora Outline Development Plan. The Canterbury earthquakes saw the development stages prioritised to make much-needed housing available early. The infrastructure was completed in tandem with the building works and all construction for initial stages was completed within the specified timeframe.
Working collaboratively with the client’s geotechnical team, Calibre Consulting provided the planning, consent, environmental and civil design. The development area had a high water table with a confined aquifer below, which was hydraulically linked to layers of peat of varying depths. The challenge was to maximise the number of units within the planning framework and site-specific conditions.
