Canal House 2 located in a sub-urban, sea-change inhabited canal estate, is a continuation of JMA’s continuing experiments designing for the Sub-tropics and has strong links with John Mainwaring’s own house (Canal House 1 -1994) built on the same street. Canal House 2 has Southern views over the water opposing a Northerly aspect to the street. Attenuating strong Southerly winds whilst still allowing transparency to the water was of paramount importance, as was creating a protected outdoor space to exploit the benefits of the climate.
To this end sleeping pods, bathrooms and laundry are stacked over two storeys on the western side of the site, insulating the long clear spaced living/ kitchen/ dining pavilion which maintains visual access to the water and a north facing courtyard. The western two storey part of the house is shielded by an insulated folded roof/wall with minimal fenestration.
By detaching the garage with a separate granny-flat above from the main house, a breezeway is created through a north facing courtyard. Entry threshold, anteroom and communal living space are brought together in the courtyard. A sheltered entry gate to the courtyard has replaced the traditional front door, and once inside the gate, the transparency of the house and view to the water to the south is obvious.
Edges to the Living pavilion are largely retractable or openable, to maximise air-flow or one side or the other can be closed depending on the direction and strength of the winds. All rooms have the opportunity for cross-ventilation and have direct or indirect distant views. Vertical privacy louvres to the street around the granny-flat pavilion can be angled for breezes and varying sun angles.
Floating over the courtyard is a large polycarbonate sky roof which links the polycarbonate skylight running through the main axis of the house. The upper level roof fold steps over the mid-level skylight roof giving protection in the afternoon summer sun. The skylight axis of the house acts as a longitudinal heat chimney, a heat blanket can be created or high level louvres can flush out the warmer air. In winter the central clerestory louvres can be closed to trap the warmth.
Set toward the end of a vehicular “dead-worm”, the street does work as childrens’ playground, pedestrian thoroughfare and connector. This pavilion’s vertical privacy fins maintain visual connectivity with the street, whilst the North facing swimming pool courtyard has acoustic and visual privacy. Surrounded by brick and stucco monoliths, Canal House 2 has been constructed out of economical and more modest materials, less about a style and more about lightness, simplicity and passive solar design – in stark contrast to neighbors who wish they were living in exotic sea-side resorts.
The simple and robust planning affords the grown family members, partners, husbands, wives and grandchildren the flexibility to spend time apart but also come together in a relaxed environment.
