A home extension in Nelson grows the rural-residential home — 1,500m² to two hectares where the 1990s+ stock takes generous wings and the land gives the designs room.
The Box Hill growth front is reshaping the area's value, so the extend-or-hold question gets an honest read, and the clay junctions are engineered where the addition ties in.
At the $2.0M to $4M+ range, the wing serves owners staying for the lifestyle the growth front cannot replace.

Lifestyle versus growth front
Nelson sits beside the Box Hill release, and some holdings carry rezoning value the extension should be weighed against — I give that read before any design spend.
For owners staying, the land takes wings the new estates next door cannot fit.
Ground and services handled
The clay junctions are engineered, and rural services are scoped where town connections have not arrived.
All of it is measured into the fixed price up front.
