Having seen some of our earlier work the owners of this extraordinary oceanfront site invited us to submit ideas about what a new house
there could look like. They had lived in a simple cottage on the site for several years before and therefore had an intimate familiarity with
the advantages and disadvantages of living in this spectacular but exposed spot.
The design process, complex due to several defining key issues inherent to the site, ended up taking us through some radically different
sketch options before settling on the one that was finally pursued.
These key issues were:
– The most magnificent quality of the site, the amazing ocean view, lies to the South while the sun still of course circles around the North.
To focus on its unique location while getting natural light inside, the house was designed around a central void with a row of large operable
skylights above it, angled to the North.
– The site is surrounded by two out-of-scale apartment blocks to the North and to the West, posing privacy as well as aesthetic issues.
– Being on the ocean front also meant that the roof height, particularly to the Southern, ocean, side, had to be minimised to reduce the
impact on neighbouring residents.
– While the original cottage already had wonderful views onto the rock cliffs across the bay a slight swing of the external wall suddenly
opened up expansive open water views in addition to the more intimate bay views.
– The Southerly wind on this site is a dominant force, as the clients had experienced over the years. Even on clear days it is strong, quite
possibly also cold enough to prevent any outdoor activity or even the opening of any windows.
These key factors together with of course countless smaller factors and decisions along the way shaped the house to what it is. The
unusual but elegant roof shape allows sunlight in while still allowing neighbours to enjoy water views over the lower end. The expressive
angled concrete wall mirrors the roof shape but in negative, resulting in a complex facade geometry along the main face, enhanced by the
movement of ever changing shadows over the shapes.
The light void also contains the central circulation, the stairs. These are light and airy without looking or feeling flimsy. To the North of the
are two levels, to the South three, taking advantage of the natural slope of the site. The main living space is on the Entry level, connecting
it with the Northern garden and Pool as a very generous central family area. Upstairs are the bedrooms, on the Southern lower level
several areas for more individual activities, Study, Studios and Library.
As a consequence of the relentless Southerly winds the house was designed, unusually and against our original instinct, without any
opening windows facing South. Instead large frameless floor-to-ceiling double glazed elements allow uninterrupted views over the Pacific
and allow a more intimate visual connection than framed openable glazing elements would have afforded.
An outdoor deck is attached to the side of the Living area, allowing outdoor activity on suitable days without interruption of the front row
feel the house enjoys.
The original Southern slope in front of the house was full of building rubble from some previous building incarnation. Once that was all
removed several large natural sandstone blocks that had fallen eons ago and stood upright, affording us an unexpected, giant japanesestyle
rock garden.
The materials for the house were chosen for a variety of reasons. First of all they had to be suitable for the harsh salt spray environment
where everything gets a thick coating of corrosive salt within a few days. They were also desired to be suitable for the location, reminiscent
of flotsam, rich but weathered. Finally, the rich natural palette of coastal colours, greys and red in the rocks, blues and greens in Ocean
and sky, provided already a magnificient canvas of hues and textures dominating large parts of the house. The rich geometry in the house
as well as the resulting ever changing play of light in the interior and exterior spaces also meant that we did not feel the need for strong
colour or texture, elements we often love to employ in other settings.
The resulting material palette relies on very few elements, the strong raw concrete, along the outside wall as well as to the living room
ceiling. A dark Zinc roof, being allowed to weather. Dark timber in floors and joinery, both offset with white walls and joinery faces. And of
course the ubiquitous glass. Both, outside floors and walls as well as interior benches are finished in the same, earthy grey stone. Having
these few elements used in a diverse range of applications throughout the house also helped to tie the many different spaces of the house
together to a coherent whole.
Environmental concerns also played a big role in the development of the design. The aforementioned central void allows natural light deep
into the heart of the house, eliminating the need for artificial lighting during daytime.
This void, supported by the roof shape in combination with the operable skylights, also helps to naturally ventilate the entire house as it
allows the rising hot air to escape, drawing cooler air behind. Operable floor vents in the Living area allow for the ubiquitous sea breeze to
be let into the house in a controlled manner, all but eliminating the need for Air conditioning.
High performance insulation and double glazing throughout in combination with the high thermal mass in the house allow for utilisation
and storage of the Northern solar heat gain in winter, keeping the house warm during the colder months.
