Set in the leafy streets of Lindfield, this certified Passive House on Grosvenor Road showcases the future of healthy, energy-efficient living. Combining contemporary architecture with world-class building performance, the home delivers exceptional comfort all year round — powered behind the scenes by a finely tuned mechanical ventilation and dehumidification system.

The design team set an ambitious goal from the outset: create a home that performs as beautifully as it looks. Our role was to supply, install, balance, and commission the indoor air quality systems that allow this level of comfort, efficiency, and airtightness to be achieved.

The home’s striking façade combines brickwork, steel accents, and modern glazing to create an elegant and timeless presence. Behind the architectural finishes lies a meticulously crafted thermal envelope — airtight, highly insulated, and engineered for low-energy living.

To support this level of performance, we designed and installed a complete whole-home mechanical ventilation and dehumidification solution tailored specifically for the Passive House standard.

At the heart of the home is the Dantherm HCV460P2 Heat Recovery Ventilation (HRV) unit, positioned neatly within the services area. This high-performance unit ensures a continuous supply of filtered, tempered fresh air — maintaining healthy indoor conditions with minimal energy demand.

To achieve Passive House-level comfort and ventilation consistency, the system delivers:

Every part of the system was installed with airtight connections and Passive House-appropriate detailing, ensuring long-term durability and optimal performance.

Sydney’s humidity presents unique challenges for airtight homes — which is why this project includes a Microwell DRY400 ducted dehumidifier, installed on the left side of the mechanical room.

This system works in tandem with the HRV to maintain healthy indoor relative humidity year-round, preventing condensation, mould risk, and discomfort.

The DRY400 supplies dry, conditioned air to:

Extract air is drawn from the hallway to quietly and efficiently maintain balanced humidity.

To preserve airtightness — often compromised by conventional kitchen exhausts — we installed a fully sealed system for the Qasair Eastmore undermount rangehood, including:

This ensures powerful kitchen extraction without depressurising the home.

Our scope included:
Complete supply & installation Balancing of all supply/extract flows
Commissioning of HRV and dehumidifier
Airtightness-appropriate duct sealing
Support for Passive House certification requirements

The result is a finely tuned mechanical system designed to work silently and efficiently in the background while delivering exceptional indoor comfort.

This Grosvenor Road Passive House now enjoys:

More than just a home — it’s a high-performance building that sets a benchmark for residential sustainability in Sydney.
