FLIPBOOK SECTION 3D: Layers of information
1. Structural Systems, below ground The proximity to the beach and the views available at the site influenced the design of the house significantly. The layout of the rooms, the large glazing throughout the house and the open plan living areas capture the exteriour and enhance the feeling of it being a beach house, which was requested by the clients. The harsh environmental conditions and the large spans required for large glazing dictated the use of material, eg. galvanised steel.

2. Structural Systems, above ground
Primary Structure
Steel frame - Universal Beam, Parallel Flange Channel, Eaqual Angle Concrete - insitu wall Timber - brearers, joists (groundfloor)
Secondary Structure
Timber - stud walls, rafters, soldiers, battens, I- joists
Bracing
Strap bracing - 30 x 0.8 galv. steel Ply bracing - 6mm F11 plywood
Ground Floor Horizontal Structural Systems, above ground
First Floor Vertical Roof
The steel framing was designed by the engineers in order to achieve large spans and allow for large glazed areas. This is to capture the view and visually connect the building parts. A timber floor was later introduced in order to achieve the necessary green star rating, as the new planning scheme allowed for a loophole.

Non-loadbearing stud walls
The internal partitions separate different areas according to their program. They mediate the privacy of the occupants and organise every day life. The frosted glazing separating the en-suite shower and the corridor is an interesting way to separate a very private from a very public area. It blurres the lines of what is intimite and a thouroughfare. The plasterboard lining allows for even paint finishes that can be changed over the years, the pivot doors allow for a smooth opening in the walls without a bulky frame. All these methods make for a smooth and simple finish thorughout the house.

4. Environmental Protections
galvanised steel to prevent corrosion due to moisture Horizontal
Waterproofing
Environmental Protections
paint - Tasman Terrasand clear hydrophobic sealer for concrete walls sarking - 55mm Bradford foil
Vertical Insulation
plasterboard - waterproof in wet areas roof - R4.0 gold batts between rafters, 55 mm Bradford foil walls- R3.2 Bradford Soundscreen batts, 2 x R1.6 batts floor - 2.5 Bradford Soundscrren batts
The largest part of the environmental protections throughout the house are being kept invisible from the outside. The insulation and sarking is within the building envelope. The sealing paint finish on the concrete wall is translucent and doesn’t interfere with the concretes appearance.

5. Mechanical and electrical systems
hot water - shower, sinks
The electrical layout is made to meet the occupants needs, e.g.. power-plugs or lightswitches next to the bed, plugs in the kitchen and bathroom for appliances etc. The hydronic heating system is chosen to have the least influence on every day life as it is non intrusicive. Also, it is laid out to allow for an optimal use of energy when heating the rooms. Positioning the trenches under the windows allows for a thorough heat transfer throughout the rooms. As both systems are hidden within the building fabric, the spaces didn’t need to be organised in accordance to the mechanical and electrical systyems. The trenches also allow for the large glazing areas, as they don’t need walls to be mounted on.
Water Supply

The physical enclosure system consists of different components. The timber cladding greys over time and reflects the intention of the architects to create a building that blends in with the sanddunes and create a true beach house. The cement cladding on the kitchen indicates a change of program in the inside. The gutter is hidden within the roof structure and maintains a thin roof profile, also enabling the building to sit within the landscape almost naturally. Roof sheet Windows and Sliding door
