Bundeena Beach Houses by Grove Architects
On the outskirts of Sydney is the village of Bundeena. This small coastal village is the perfect place for a beach house retreat and is the place Architect Grove has been commissioned for the Bundeena Beach House project, a compact modern residence with a lively roof and stunning views.
Weekend holidays with a strong connection to the environment, this is the context home. Home environment. Home part. A house with an original roof garden as its main height, and a sculpture ceiling as its main interface. A house with pleasant interactions between inside and outside, public and private.
The house does not try to relate to the context it is building but rather contrasts with it, giving a little relief on the road. Because it is low, this house presents its roof as its main height. Considered an original park, the roof announces houses to the community, connecting the road with water and expanding adjacent reserves. A sculptured sky lamp shines at night, signifying the house below, drawing sunlight inside, and connecting the inside to the outside, encouraging pleasant interactions with the movement of the sun.
Under the roof, the house is conceived as an object in the landscape. A corten sleeping box appeared from a hill, floating above a living glass box, intersected with a wooden multipurpose box. Clearly articulated, each box is wrapped in a durable material, chosen as a direct response to the beach location. With corten screens perforated fixed to the window of the sleeping box and fixed pergola to the living room of the glass box, the operable element is minimized to reduce maintenance in a corrosive beach environment.
This house serves to connect residents with the landscape below and outside while involving them with the transience of the environment around them. It utilizes the environment for light, wind, heat, energy, and water while protecting its inhabitants from the harshness of its elements.
Large ceilings and vacancies invite sun penetration throughout the day. The shape of the butterfly restricts penetration to strategically oriented vertical triangular panels, preventing overheating, while encouraging playful interactions with the movement of the sun. The openings are controlled by a perforated screen fixed to the upper level window, and a pergola to the lower level, providing protection from the western sun.
In addition to its ecological benefits, a green roof reduces heat absorption, provides insulation, and reduces solar heat and heat loss. The collected rainwater is recycled to irrigate the garden, while a sixteen 5.7kW panel photovoltaic system and Tesla battery, seen as a linear reflection pool in the roof garden design, provide all the owner’s electrical needs. It is important with PV panels, that these panels are integrated thoroughly into the design of a home garden and roof, serving as an example of how environmental features can increase, not reduce, the design.
The house is gas free, with PV providing all the electricity, hot water, heating, cooling and cooking needs. The only fossil fuel used by the home is a minimum electricity surplus from the electricity grid. Although using rainwater collected for garden irrigation, the house itself is connected to the main water supply.
