1. Structural Systems, below ground

Concrete Slab

How did the site condition affect the design of the house?

Compacted Fills

The old house sits on a flat site in front of the lake wendouree, in response to this site condition, the architects want to create an artificial terrain house which has some level change inside and outside of the house. In order to achieve this outcome, they tried to rise the ground level up by adding the compacted engineer fills above the soil. The void formers are also used in order to save the usage amount of the concrete.

Horizontal

Another site condition which effects the design of the house is the facing lake orientation. The interesting design of the front living room window glazing and upper main bedroom terrace opening are shaped for a better view of the lake.

Since its a long site from north to south, the architect tried to put the garage and gym at the back of the site and the swimming pool in the middle with the path parallel to it. Courtyard is designed in the middle of the house.

Vertical

300mm wide 385mm min. deep internal beams are installed in between the void formers and reinforced by 3-N16 Bars.

Block Wall

140mm Core filled concrete block wall are built around the dining room area as one of the vertical structure systems.

Retaining Wall

220mm thick concrete retaining wall are built at the corner of the kitchen and conservatory as the vertical structure system.

Strip Footing

400mm wide 600 min. deep strip footing are founded into stiff clay in the garage area at the back of the site.

Pad Footing

The steel meshes are fixed on the void formers by the chair bars as the reinforcement for the concrete floor slab.

1000 SQ *500mm min. deep blinding concrete pad footing are installed centered beneath the steel columns

Two types of Pad footings are both poured intergral with the blinding concrete beneath edge beams.

Three 2000 *1000* 500mm min. deep blinding concrete pad footings are installed under living room area at north part of the site.

Concrete floor slab Some of the void formers are cut into small size to match the position of the concrete slab and the blinding concrete underneath.

Compacted engineering fills are used in this house project to rise up the floor level which create an artificial level change through the whole house.

Compacted engineer fills are installed between sand bed and soil to create the artificial level rise on site which achieve the architect’s needs.

Internal Beam

Foundations Structural systems, below ground

The 120mm thick Concrete suspended Floor Slab is poured at the top as one of the below ground structure systems, they are reinforced by the steel meshes and void formers inside it help to save the usage amount of the concrete.

Steel mesh 15 MPa Blinding concrete will be founded 200mm Min. into stiff clay which refers to the soil report on site.

2. Structural Systems, above ground

250 x 150 x 6 RHS, 200 x 100 x 5 RHS, 89 x 89 x 6 SHS and 150 x 100 x 9 RHS are the steel columns installed on the ground floor to support the structure.

How does the structure define the composition of architectural form and space?

The first floor master bedroom terrace and downstairs living room openings’ steel structures are designed to form the unique shape of the glazing to achieve the view of the lake. The inside and outside composition of the bedroom structure are matched to form the irregular shape of the ceilings and spaces.

75 x 75 x 4 SHS columns are welded under the 200 PFC beams to hold up the structure of the moveable door in the living room.

The brick pavilion in the front of the house is different form the zinc cladding external finishes on the back of the site (three bedrooms) which is the transfering from heavy to light.

180 Universal beams are installed on the first floor master bedroom as the primary structure to hold up its roof.

3. Internal (non-load bearing) partitions

The non-load bearing stud wall on the ground floor are installed for dividing the space for the ground floor powder room.

How do the internal partitions organise the life inside the building?

The stud wall located between the kitchen and hallway is also non-load bearing which only dividing the space inside the house.

The internal partitions are dividing the space inside the house to separate different parts of the building. The sliding door and operable doors for the bedrooms can be seen as the objects which can zone off the space for the first floor living area and form a closed big space for the client. Another interesting partition is the movable door in the living area, it divides the space between living area and the kitchen dining area. But the space behind it is not completely exposed since the space can be orgainised optitonally by the situations and it can change the moving circulation inside the house.

Fixed

The movable doors on the ground floor dining area are considered as one of the non-load bearing internal partitions and they are cover by the special timber cladding as the outside claddings in dining area of the house. They are installed in the further steps but not the same time as the other internal partitions.

Internal Partitions Movable

The timber sliding door of the master bedroom on the first floor are installed later for dividing the space of the bedroom and the upper living area which seen as a movable internal partition.

4. Environmental Protections How did the architect approach the design of environmental protections? Do the elevations express or hide environmental protections?

The 6mm thickness rainwater cappings are installed on the ridge of the roof above the study room and other edges of the roof to achieve good waterproofing outcomes.

There are different types of gutters, downpipes, insulations designed to install for the house and they are all environmental protections. All the insulations are hide inside the timber structure or in between the external walls. Flashings of the brick wall are hided but the weep holes are exposed outisde. Some of the downpipes are exposed but all the downpipes in the front of the house are hided behind the brick wall in order to make a better appearance.

The 125mm custom folded eaves gutter is installed on the east side of the house to collect the rainwater and they will finally fall into the Zinc downpipe (100mm diameter) connected to it.

The 0.7mm thickness Zinc box Gutter are installed on the roof of the main bedroom to collect the rainwater drop on the roof of the house. And the downpipes are not exposed outside but covered by the brick wall, there is a overflow duct on the side of the sump to allow exceeded rainwater get away from the house.

210mm thick thermal insulation with R-Value 4.1 are installed on the roof and ceilings of the house to control the temperature inside the house.

120mm thick thermal insulation with R-Value 3.0 are installed on the level one floor between floor joists.

The flashing are installed for the external brick wall of the house which into notch in underside of the window frames.

120mm thick thermal insulation with R-Value 3.2 (2*1.6 Batts) are installed in between the external brick wall and the timber wall structures.

88mm thick thermal insulation with R-Value 2.5 are installed inside the internal wall of the house.

The flashing installed on the edge of the roof helps the rainwater to fall onto the roof sheetings and finally collected by downpipes.

5. Mechanical and electrical systems

Water are supplied through the pipes from the water supplier and recorded usage by the water meter.

Did the architect organise the internal spaces to place mechanical and electrical services efficiently?

All the pipes and wires make the way for mechanial and electrical services to run through the whole house on both ground and first floor. The architect efficiently organised the internal space for these services, they are mainly run on the ceiling and pipe are on the wall to provide bathroom hot and cold water. Air conditioning unit is placed on the ceiling above the dining room which covered by the ship lapped timber board and save the space of ceiling since dining area has a very high ceiling. The heating panels are installed on the wall which only occupy a little space.

Almost all the service outside units are placed on the east side of the house including the air conditioner condenser and hot water boiler.

Water Supply

Essential services

Electricity are supplied mainly from the electricity supplier to the house on site.

First come to the switchboard and then to the GPO and other lighting and services.

Elecricity

Solar panels on the roof provide some electricity and through the solar energy inverter to become the available electricity which can be used for lighting or heating the water.

The thermostat hydronic heating are installed on the bathroom and ensuite floor for heating purpose.

6. Physical Enclosures systems

The 1mm perforated aluminium sheeting are installed for the roof area above the main bedroom terrace.

Do the physical enclosures express aspects of the building (internal spaces, structure and materiality)?

The external physical enclosures consists of many different materials which has heavy brick wall on the front of the house, zinc cladding on the east side first floor external wall and the timber batten ship lapped board cladding outside the dining area. These give people different sense of feeling when looking at this building, from heavy to light from front to back.

The internal finishes define different spaces with different materials, in order to match the external wall outside the dining room, architect designed to used same material for inside kitchen and living area partitions.

The structure of the house is Horizontal completely hided by the finished Enclosure excepted the conservatory area.

Systems Vertical

The Vertical ship lap boards claddings are installed on the facedes of the dining area with 42*90 and 42*42mm spotted gum timber battens screw fixed to the back of the cladding board.
