About this home

Ascot Passivhaus is a rural family home with an attached workshop designed to meet the needs associated with living and working on a farm.

It has three bedrooms with a similar sized sitting room (or 4th bedroom). The Master Bedroom has an ensuite and WIR. The living room and kitchen are in one area with a separate “Butler Pantry”.
A full-length East/West passage services the whole house. At Equinox, the setting sun shines through and out the other end of the house through both the triple glazed doors.

Large picture windows allow for country views all year round. A protruding eave on the north shades the summer sun, while allowing for full winter sun access. Externally the house is clad with Corrugated iron and tilt panel walls for a robust low maintenance finish designed to withstand the harsh elements associated with this exposed site.
A standout feature you will notice straight away is the calmness and quietness that hits you when you enter the house – no matter the weather outside.

A Passivhaus is built for levels of comfort and health benefits not obtainable in conventionally built houses. The strict criteria required to build to the Passivhaus standard is there for this reason. The house is free from draughts, external pollutants, and condensation with the associated mould risk.

Stale moist air is removed from within the house, replaced with filtered fresh air without compromising the comfort of the internal temperature. This is via the Mechanical Ventilation and Heat Recovery system. To achieve this level of comfort and health benefits, by default, a Passivhaus is also extremely energy efficient. You do not have one without the other.

This property has wheelchair access.

Q & A

What motivated you to build or retrofit sustainably?
A learned understanding of building physics convinced me this is so important.
Airtightness coupled with Mechanical Ventilation and Heat Recovery means the house is liveable and healthy, as well as ensuring the high level of insulation performs as it is supposed to. Moisture and water vapour control is achieved with the building wraps used, removing the risk of mould and structural damage. The triple glazed windows have a Low-E coating to prevent overheating, an especially important consideration with very energy efficient homes. The insulation is continuous around the whole envelope, floor, walls, roof, with thermal bridging eliminated. This is important in preserving energy and preventing condensation damage to the structure.Ceiling fans make a significant difference even superseding the need for air-conditioning in most cases in summer. Highly recommended!
I would not have included the 2.5kW split system air conditioner in the Master Bedroom, but would have included a ceiling fan instead.
Work on bringing the cost of building down by experimenting with and considering other ways, materials and methods of construction.
