Environment issues are very popular now. People try to use a lot of things that are more friendly to the environment. Some architecture designers also cover this issues. Riddel Architecture has completed their project to build a new high end private residence constructed almost entirely from the house it replaced. The handover of the keys to the proud owners of the Hill End Eco-house occurred on the 19th of March. This house use almost 80% recycled materials from the 1930s house that originally occupied its narrow riverfront site. Because of this facts, this house become popular and has attracted media attention as far as Norway, China and New York

Riddel Architecture team, David Gole and Emma Scragg worked in collaboration with Robert Peagram Builders to realise its vision of creating a high end home that was based on environmental principles. Recycled materials were carefully detailed to become design features throughout the home.  The design of this three-storey Ecohouse relates to the subtropical Australian climate with openings maximised to capture cool breezes, sun and daylight. The house is in two halves, connected by the striking Gallery breezeway, which acts as a funnel for fresh air. Throughout, large windows provide views of the surrounding river landscape whilst reducing the need for artificial light. An informal and relaxed lifestyle is encouraged by the open plan layout and the timber and tin aesthetic conveys a sense of the Queensland character.

The Hill End Ecohouse is fully self sufficient in both water and power and has a monitoring system to measure the use of energy, gas and water as well as temperature and humidity. This system also provides a carbon footprint for the house. The north-facing roof has 3kW photovoltaic panels which generate 15kWh/day, ample energy for household requirements.

To reduce heat transfer, they have recycled polyester bulk insulation and timber frame. They also use solar gain captured by the light, polished concrete floors and well-insulated walls to provide heats on winter. An efficient gas fire provides winter heating to the southern living space, where solar heating is not possible.

60,000L of rainwater storage supplies the whole house and garden. House rainwater is pre-filtered, heated by solar panels and stored in a well-insulated tank. To reduce water waste, a hot water recirculation unit reheats cold water and greywater is treated and recycled on site

Outside, the building and windows have light coloured finishes to increase the reflection of daylight and generous awnings provide protection from the sun and rain. The spacious bedroom and living areas open onto beautiful outdoor spaces with lush plantings.

A drop down blind to the River Terrace provides shading from the morning sun whilst the north street-facing balcony is sheltered by a vegetated trellis made using recycled timber from the original site. The landscaping features woodchips from removed trees and gravel crushed from original concrete slabs.
