Design-led water management for a modern home on a steep block.

This luxurious 3500m2 property in the inner city suburb of Red Hill in Brisbane resided on a battle-axe block, surrounded by other residences.The site retained asteep slope and a water course easementthrough the property.There wereoverland flow issuesfrom neighbouring properties that required water management.We were excited to solve these issues while complimenting thenew modern homeon the property and theenvironmental requirementsof our green-minded clients.

Turfed space

A large turfed space opened the yard and gave ‘breathing' space from the towering trees to the neighbours' boundary. Asloped turfed zonealso combatted against the worst area for erosion and provides a fun play area for the kids to roll down.We stopped the turf where the maintenance would get too difficult, removing the requirement to mow on a slope.

Planting

Native and indigenous plantingwas chosen in keeping with the importance of environmental sensitivity for the property, as well as attracting fauna.Grey-green foliage plants contrasted with the lush green planting, and imitated the grey tones of the building and dry creek bed.Tall trees were used to screen neighbouring properties and to frame the building. Stabilizing grasses and groundcovers were chosen to aid in erosion control.

Easement

Water flows from the surround land through the ‘gully' of the property during heavy rains, causingerosion and floodingof the driveway.

We chose to use bluestone rock for the easement, to compliment the existing highly visibile bluestone wall on the boundary of the property.The bluestone was quarried from a local site - the local material reducing the environmental footprint of the project.The rock colour also matched the colouring of the building and the angular shape complimented the modern architecture.

We used the bluestone rock in gabion walls (feature and retaining), and gravel-sized for the visitors' car park.Large boulders were used as retaining walls.Extra large boulders brought a sense of scale to the large block.

Pool Design

The pool fencing required special treatment as it was to the front of the house.We choseframeless glassto two parallel sides, allowing views from the building through to the landscape and gardens beyond. A timber screen at the end of the pool provided privacy between the pool and the building entry. Timber used in the building was replicated and linked the landscape to the building. Grey granite tiles married with the building and feature rocks.

Materials

Recycled railway sleeperswere used as steppers and stairs and a sandpit for the kids.We also used sleepers to create a bridge over the creek bed.
