1. Structural Systems, below ground Structural systems, below ground

How did the site conditions affect the deisgn of the house?

For the Lake Wendouree Residence, the existing site and landscape condition have big influence on the building designing process. The site condition includes soil condition, climate change, energy supply, existing landscape etc, which are all need to be well considered during the designing process.

Firstly, it is siginifant to check the soil consition as one of the most important part of site preparation. The soil testing is done by workers and a site report is completed before constructing of the site. According to soil report, the site is labelled as P (problem site). Therefore, stiff clay is used under concrete footing to enhance ability of bearing vertical loads.

In addition, in order to create better view for lake wendouree residence, the internal layout of the house is designed with large galzing. For example, bedroom and living room are facing lake that located near the building, which provides more visual connection between indoor space and outdoor environment.

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

Ground Floor

Structural Systems, above ground Vertical

The internal layouts of Lake Wendouree Residence is well considered and funcitoned. The ground floor is mainy the living room which constructed by timber stud framing, steel columns and steel beams to bear loads. In addition, the overhang part in the first floor supported by steel beams mainly, which enlarged indoor space in first floor and forms kitchen area.

Structural elements constructed in first floor provides support for roof system, which seperated interior space and exterior space. The steel structures of ground floor are designed to support large glazing, which brings more natural light for building.

3. Internal (non-load bearing) partitions

Stairs

How do internal partitions organise the life inside building?

The internal walls divide whole building into different areas and seperate different activities according to functioned places. For example, bedroom is formed by internal walls and it is more private than other area. In addition, internal partitions can also enhance the connection between indoor and outdoor but still keep them seperately. The sliding galss door near the courtyard provides more visual connection with environment and allows people interact between courtyard and interor space. Moreover, fixed partitions such as stud wall divides kitchen area and hallway depending on different functionality. However, the space is not entirely independent because the kichen is not closed with door, which makes space more free.

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

Environmental Protections

Architects hide most of the architectural components and only expose some of the essential material elements, which is for environmental protections.

For roof system, the materials of all the exposed elements such as roof sheeting , box gutters and downpipes are choosen carefully to match the external cladding and surrounding landscape. External wall are covered by external cladding to keep the material consistency. The solar panels on the roof supply electricity for the Lake Wendouree Residence, which is beneficial for environment and energy efficiency. Due to the overhang of the first floor, ground floor underneth it may be hard to gain natural light, which might result in increased usage of lighting for kitchen. To gain more light for ground floor, large double glazing is installed for the facade of kitchen, which is another way to lower the energy usage to achieve environement protection. Rainwater tank stores and recycles rainwater to reuse it.

Plasterboards installed under ceiling structure as protection and provide flat ceiling surface

5. Mechanical and electrical systems Did the architect organise the internal spaces to place mechanical and electrical services efficiently?

Water Supply

Essential services

All the mechanical and electrical services are organised in a simple way within the internal spaces. To achieve higher level of safety and more cleaned interior space in the building, architects minimise the exposure of pipes and wires. Pipes and wires are hidden inside of flooring system, wall system and some of them run through roof system. For example, the electric wires are hidden inside wall and are connected to electronic switchboards and powerpoints directly, which is helpful to prevent wire aging and increase ability of water resistance.

HVAC is placed near the dining room that is the center of the ground floor, which provides balanced heat transferring to other rooms in ground floor. Also, heating and cooling system are placed depending on specific situation. For instance, bathroom needs extra heating espeically when people are showing. Therefore, an air-conditioning is installed on the roof of bathroom. Water pipes are mainly placed around kitchen and bathroom that are spaces require large amount of water supply.

Enclosure Systems

6. Physical Enclosures systems

Interal space

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

Plaster Board

13mm Plasterboard with white color

Stone tiles

Pietra Bronzea Brushed stone tiles for bathroom

Timber decking

Physical enclosures including roof system, flooring system and wall system (including windows, skylights and other elements that defined space). The physical enclosures seperate the space inside building and space out side building. For example, building facade and roof system form a more private indoor space. Also different materials are used for front courtyard such as brick, timber, glass, which provides unique outdoor experiences. Simple cladding wall, using of large glazing form modern style of the building.

Physical enclosures also divide whole building into different areas. The internal walls defined different functioned areas such as bedroom and bathroom. Different flooring materials also represents different indoor areas. For instance, bathroom uses tiles as ground for waterproofing. Timber decking are used mainly in the first floor, which shows first floor is more private than ground floor (living room).
