Whitehall

This thoughtfully designed eHaus is Marlborough’s first certified Passive House. Built to perform, the home features 190mm thick walls, triple-glazed windows, and exceptional airtightness, delivering year-round comfort and remarkably low energy use. Inside, the spacious layout includes three bedrooms, with a generous master suite complete with walk-in robe and ensuite. An open-plan kitchen and living area connects to a separate media room and office, offering both space to entertain and quiet corners to retreat. A covered deck extends the living outdoors which is ideal for Marlborough’s long summers. Designed and built for a couple downsizing from a draughty 1920s bungalow, this home will provide a far more comfortable retirement than their previous home.
