House, Tutorial
The existing site conditions significantly influence the design and construction of the Limestone House, adapting to soil condition, neibourhood environment, solar aspection, civil system, site boundary, etc. This is a passive residential house deisgn, aiming achieve high energy efficiency, which means a comfortable internal temperature using minimal energy input.
Limestone House at 3 Leighton court, Toorak, Melbourne, Victoria, Australia, extends west-east, measuring approximate 35m in length and 14m in width. The total site area is 675Mm2. The house has 3 levels in total, one in basement and two storey above ground.
The soil report classified the site as a Class P/M. Class P refers to problem site with soft soil, and Class M refers to moderately reactive with moderate ground movement around 20-40mm. Therefore suggesting the use of compact sand bedding and fine crushed rock as subgrade layer in accordance to AS 1289. The soil condition in this way impact the material and depth of engineered compact fill.
Limestone house in Toorak has average temperature of 19.2 oC. The annual daily sunshine in Toorak is 6.55 hours, which encourage the design to set solar panel on roof in which to gain solar energy according to passive house design. The average anual rainfall in Toorak is about 799mm, and a nature pool is located at the north side of the site. Therefore slopy roof is designed with multiple pit and gutter, leading rainwater to the harvest tank underground, on the north side of the house.
The house entrance is facing to Leighton court, which impact on the maintainence of privicy in street facing elevation. The design then cut windows into the stone surface to provide evidence of inhabitation.
Due to the long extend of house, an additional opening is carved out in north elevation with a significant outdoor space in the centre including a planted pond with a floats timber study (His study), which forms the centre of the house around other arranged spaces. Moreover it provides north sun deep into the house and allows for distant view and provides strong connection to the cengarden.

2. Structural Systems, above ground
The structure system of the house has strong interconnection with the composition of architectural form and space, the structural system in to define both the external form of the house and the internal division of space.
The use of a hybrid structural system coomprised of timber and steel. Timber framing is necessary to provide structural integrity and material efficiency alighed with the energy efficiency aim of the house design. Steel beam and post allows for opportunity to take heavy load structure.
The use of structural steel columns and lintals allows for larger span for the openings such as a continued picture window in the design.
The sloped roof sturcture allows for rainwater collection. TImber framed brick venner structure with blockwork retaining walls where required in intended for the living space to read as a submerged pavilion within the landscape. It does this through grounding itseld with the use of masonry.

The design has a centre area with a timber study structure of His study, therefore a connection between the corridor and the His study need to be construct. The internal partition forms a transition hall way between these two spaces.
The Limestone house is intended to construct as a high energy efficiency house, therefore lots passive design strategies are used to approach the environmental friendly and protection. Well performance insulations and triple glazed window panel has been used throughout to maintain a comfortable temperature inside the house. Therefore less energy will use for cooling or heating the house. The house is self-sufficient in managing the water and electrical system. Gutter and pit is located on the sloped roof to collect rainwater to the tank. Waste system in addition to support the house water usage. Photovoltaic cell system above roof with battery storage to support house electric use and meet the house’s total energy needs. The tree and water pond helps to cool down the temperature in site. All timper products are surable recycled Australian harwoods, which reduce the cutdown of trees inordeer to keep environmental friendly. Limestone cladding is transported from South AUstralia, siltstone floor tilling is transported from Queensland, recycled spotted gum and black butt timber cladding, flooring and internal lining are from NSW and Queensland. All source of materials used in the house are from locations near to site therefore less energy output during material transportation.

The arrangement of internal spaces is efficiently designed to divide the house into zones for mechanical and electrical servics. Mechanical services centered at the eastern side of the house in the garage.
Rainwater captured from the roof is stored in the underground storage tank, undertreatment to the potable water standard, and reuse to support house water usage.Greywater is captured from the shower and lundry, and reuse for toilet flushing. Solar panel installed on the roof in an angle to best receive solar energy. The solar enery will connect to the inverter and support the house electricity usage. This eletrical and hydraulical system support the passive design intend for Limestone house.
Good ventilation helps to maintain a comfortable room temperature as well, except from natural ventilation, air conditioner, grilles, air diffuser and exhaust fans helps with air movement.
Adjustable louvre installed above in the centre may adjust the sun shading and aire movement as well. Allowing more sunlight in during winter and block sunligh in summer can effectively change the indoor temperature.

The installation of physical enclosure system reflects the overall design appearance which can be tell from the name of the design ‘limestone house’. The external facade of the design mainly used limestone veneer. Meanwhile the external facade of the His study as a separate space is wrapped with timber cladding. The building envelop of the Limestone house is robust and soilid. The material using of limestone externally is in silver grey, it in addition forms the robust and stron expearance. Also, this natural material do not need long term maintenance, therefore match with the passive house approach as well.
