Garage Mahal Home open for Sustainable House Day!

Virginia Creeper green wall is located on the North and West facades using heavy duty galvanised steel cyclone mesh mounted on a heavy duty steel frame to provide shade and protection from the summer heat, and being deciduous allows the winter sunshine to penetrate for winter heat.

The vertical green wall had to be engineered off and approved by local council and was designed for two stages, first at 4.5 metres in height (which is its present height) with the intention to go up to 6 metres in height. Importantly the structure was engineered and approved for the 6 metre height.

Currently at a height of 4.5 metres on both sides of the building, the GarageMahalHome Vertical Green Wall growing in Lois Lane near Fremantle covers 126 square metres and is the largest green wall in in Western Australia at present.















:: vertical greens walls are designed to be integrated into the building in many ways especially with a northerly view which has a 1 metre wide breeze way between the building and the wall using weld mesh ex-mining commercial components. (refer to photograph below)

:: the choice to grow a food producing green wall was considered.

:: the performance of the deciduous vegetation was critical, in that it had to be fast growing with minimal maintenance, ideally providing complete shade in summer for cooling the building, and becoming bare in winter for thermal heating.

:: text taken from the plant label used in the vertical green wall:
loves the sun, part shade, hardy to frost , and grows to a height of 15 metres.
A tough deciduous climber that has brilliant red autumn toning, blackberries are also produced in the autumn. A great climber for exposed (or ugly) walls since it is a self clinging climber there is not need for support and able to grow quick in height if required"

The Virginia creeper is planted every 1.5 meters apart beneath the cyclone fence wall structure. Watering is handled by a subterranean drainage system coming from all grey water outlets on the property. There are also surface drain uprights that feed to the under ground drainage system for additional watering during extreme heat if needed.

I believe that in 2 years time the creeper will need to be thinned as the creeper timber vines will slowly fill in the cyclone mesh becoming a beautiful organic woven vertical green wall, but preventing winter sun from penetrating. The vertical green wall is positioned 1 metre off the building on both sides creating a breeze-way working as a channel for cool airflow around the building.
