Water Sensitive Urban Design tour – part 3

Part of the fabulous green wall

Last stop on Marrickville Council’s Water Sensitive Urban Design tour was an old factory in St Peters. The owners Ricci & Judi have renovated the building into a residence with separate space for artists’ studios.  The building is thought to be built in the 1870s & to support this theory, a 1872-penny was found under the front door foundation during renovations.  This property has a number of amazing features & after reading the information sheet handed out by Council staff, I know I have missed things during our visit.

On the ground floor, where trucks would have once made deliveries, they have kept parking space, but have made a green wall & suspended a water tank 3 metres above the ground & against a wall. The green wall is lovely to look at & is watered by a well thought out drip-feeding system.  Rainwater from the 200 square metre roof of the property is captured into 2 rainwater tanks. The first has a 3,500 litre capacity & feeds the 5 toilets & the washing machine. Another 1,000 litre tank captures the overflow from the first tank & the water is used for the garden areas.

Water is pumped from the rainwater tanks to the rooftop garden. Here there are tough native plants & trees plus a vegetable garden that is growing well.  After watering the plants here, the rainwater filters through a series of pipes to water the vertical garden & an onsite rain garden.  Any overflow leaves the property to eventually flow into the Cooks River.  All the drip systems are hidden. You get the green feel & outlook without having to see pipes, although they wouldn’t look out of place anyway.

The rooftop garden is a delight & reinforces my desire to have these become a norm in Marrickville LGA.   One other thing about green roofs that I have written about previously is that they last around 3 times longer than ordinary roof treatments so it makes economic sense to create them. In this rooftop garden, 3 layers of waterproof membrane have been installed. Planter boxes have root barriers & drainage cells are at the bottom of each planter bed. These capture rainwater & any excess is channeled to the drains & used in a garden somewhere else on the property.

Ricci & Judi have reused most of the building materials in the property for the renovation. They have even made some very nice tables from old wood on the site. Essentially, this family recycled a most of the building materials that were on the property & much of what they brought from elsewhere was also recycled.

They don’t waste any natural resources, yet manage to live in a lovely & creative environment.  Although this is an industrial building in an industrial area, there are areas of great beauty.

There is much that I have not covered in all 3 properties.  If you are interested in this sort of thing & want to save money & lower your carbon footprint, I highly recommend attending this free! tour.  I’ll post details if I hear when a tour is available.  Well done to Marrickville Council for organizing such an activity & to their staff who were friendly, helpful & made sure we were not left behind.   They also watered & fed us which was an unexpected treat.  Do this tour if you can.

Thank you also to the residents who kindly opened their houses for us to see.  Your sharing has inspired us & shown that environmentally-friendly changes can be done around the home without too much trouble & with great outcomes.

I made a short YouTube video of  this residence here – http://www.youtube.com/watch?v=UhtvOqHUl28
