The Exbury Egg
“Building and crafting a shape like this is an unbelievable challenge, and this project is one of a kind. This extraordinary shape provides somewhere to live, work, create and most interestingly to float.”

Rain Water Harvest
We are mindful of our responsibility and our impact on nature. Not merely the sites we work with but also the wider environment by the consideration of a building’s lifecycle. We believe that sustainability is complex and don’t believe that you should just rely on bolt on technology, it should be considered from the outset. We do this automatically in the way we approach design.
Anchored like a boat to the bed of the Beaulieu River in Hampshire, England, this large wooden structure floats with its lower part concealed below the waterline as it rises and falls with the tides.
The brief … to design a temporary, low-tech, off-grid, sustainable space that would provide artist Stephen Turner with somewhere to live and work for a year. It would need to be sympathetic to its environment and, just to make things a little bit more tricky, its final location would be a sensitive conservation area.
As the artist in residence, Stephen would use the egg to observe this fascinating, changing environment, studying the water’s edge between high and low tides observing the landscape for effects of global warming and tidal erosion. The egg itself was to become part of the environment, weathering with the elements as the year progressed and engaging with the flora and fauna of the water.
Measuring 6 x 3m (20 x 10ft) …the egg is designed to move up and down with the tides. Solar power is harnessed as the energy source with the project following the principles of ‘lean, green and clean’ and ‘reduce reuse and recycle’.
The simple interior echoes the ethics and principles of the exterior. The egg was not destined to become a sleek luxurious residential space, instead, fitted out with the bare essentials needed to live a modest and simple life – a bed, a stove, a desk and a wet room, with enough power for a laptop, mobile phone and digital camera.
The exterior of the egg was clad in cedar wood - much of which was recycled from old shed and garage doors. For the egg to be watertight whilst retaining a natural unfinished wooden exterior to display the effects of weathering and erosion, the cedar was double layered with a layer of glass epoxy placed in between to create a waterproof barrier.
Various solutions were explored which would enable the egg to rise and fall with the tides while staying upright and stable without rotating. Tow weighted fins were applied to the egg, like a twin keel on a boat, stopping any possible rotational movement.
The egg is such an everyday shape that we hardly ever stop to question it, but in design and architectural terms it is a very complex structure. This egg, undoubtedly was a technically challenging project; a hybrid born from the worlds of art, science and architecture.
