Japanaese/FLW House, Jack & Margaret Scott from Ashburton have built several times before and had some very good ideas of there own that they wanted to incorporate in their new home. They have an admiration for Japanese architecture and they are also fans of the late great American Architect Frank Lloyd Wright, particularly his early prairie houses. In short their brief was for a ‘Japanese / FLW’ influenced house, timeless and with reference to the past. Now in their 80’s, still very mobile but thinking ahead, they wanted a comfortable, warm home, incorporating energy efficient design ideas and what they playfully describe as “geriatric-friendly” design (an accessible house) and eco-friendly.
Following Japanese architectural philosophy space planning is economical and detailed, interior spaces flow from one to another without need for a long hallway. A centrally located entrance way made easy access achievable.
An understated and slightly mysterious feel from the south facing street side is due minimal windows and an outdoor walkway/atrium leading to the hidden entry door.
Top of the design brief was eco-friendly and energy efficient.
One example of preference for sustainable materials is the use of large exposed timber beams instead of steel. These also provide the desired Japanese aesthetic.
The house uses no electricity for either water heating or space heating. The conservatory was designed as the heat collector of the home. The large glazed roof allowing in all-day sunlight, and a fan facilitates the flow of the heat to other parts of the home. Argon gas filled, Low E double glazing with thermally broken aluminium frames provides the best possible thermal performance.
The floor slab is 50% thicker than normal and provides the required thermal mass. It has 100mm foam insulation under and is completely isolated from the foundation eliminating any thermal bridging. Detailed thought has been given to passive solar design ideas and details of junctions to minimise thermal bridging.
The highest efficiency log burner available is connected to the hot water cylinder. Large Solar panels are installed on the roof and north wall. The solar and the log burner are completely complementary and both are connected to the underfloor heating. The solar provides 100% of the hot water in the summer and the log burner provides the backup in the winter and keeps the house cozy. They don’t have photovoltaics as yet, but have the provisions built in to install them once a more efficient model is available here in New Zealand making it then a totally off grid home.
