CREATIVE SPACES CB02 / ROO RUN HOUSE CASEY BROWN ARCHITECTURE
This 3 bedroom house makes the most of the Australian
countryside by creating generous indoor and outdoor spaces
for modern lifestyles. The building’s design entails a simple
economical plan with a distinctive roof- lower over the bedrooms
at either end and rising gently over the central living areas.
The central open plan living area with decks to both sides enjoys
year round natural climate control. It is able to be fully opened
up and has high ceilings making it adaptable to a variety of
climatic locations.
The house incorporates a separate carport and storage space.

Environmental Control
The design of plan and section maximise natural ventilation
to provide a comfortable living environment. A deep pergola
to the north provides shading to the main living space. Large
openings and high ceilings to the centre of the house allow
good cross ventilation and air movement.
The house is elevated o! the ground to keep the building dry
and free of damp.
In contrast to the living area, the bedrooms are more compact
to retain heat.
A wood burning " replace in the central living space provides
heating.
The elevations are characterised by adjustable louvres, insect
screens and large sliding doors.

Energy Management
The house combines passive solar features with active solar
devices to minimise energy consumption.
Wide eaves and a deep pergola protect openings from direct
sunshine. The fully openable central living area encourages
natural ventilation to all rooms. East-west orientation of the
plan allows the large living area openings to maximise winter
sunshine to the internal polished concrete ! oor acting as a heat
sink.
The house can be mechanically air conditioned or hydronically
heated if desired.
* Photovoltaic panels can be integrated on the northern slope
of the roof, with a potential production of up to 4 kWh using 16
panels of 1650 x 1000mm photovoltaic panels.
** All hot water will be solar heated with collectors on the
northern carport roof with tanks in the garage store. The pitch of
the garage roof can be adjusted to best suit the optimum solar
angle depending on the location.

A" ordability
Note:
Above pricing is current for the year 2014, based on
construction cost in Brisbane, Queensland. However, the
construction cost will vary depending on location, speci! cs of
the site, choice of materials, etc. To obtain an accurate ! gure, it
is recommended that a minimum of 2 local quality builders be
asked to tender for your speci! c requirements.

The clever use of space (making sure the building is not too big
but big enough) allows a compact building design which in turn
ensures building a" ordability.

Addition of steps at front and rear is possible depending on
slope. Cross fall of up to 5 degrees can be accommodated in the
design.

Site Variations
Case study house 02 is designed for near level North to South
blocks. The design can be adapted to suit the speci" cs of
the site, within certain limits. This includes adaptations to
gradient(slope), orientation, access, retained trees, views and
adjoining buildings.
It is recommended that siting is done in consultation with the
architect to ensure optimum solar access, shading and general
consideration of other site features.
