The inspiration for the concept derives from OAS1S head Raimond de Hullu. Hullu imagines a pedestrian-friendly community, with no cars in sight. Residents would reach their homes by parking on the fringes of the development and taking a stroll through the ‘forest’. An OAS1S community would feature a maximum of 100 houses per hectare (2.47 acres), and include single and multi-family housing, hotel and office space, in addition to leisure and commercial units covered with green roofs.
A typical treescraper would measure 6 x 6 x 12 m and comprise a total floor space of 160 sqm split over four floors. The interior would include a dining room, deck, hall and storage area, two bathrooms, a lounge, utility room, and three bedrooms, in addition to a fenced balcony and glass-bottomed hall on the top floor.
Each treescraper would be covered in greenery and, in order to operate off-grid, would sport sustainable technology such as solar hot water and electricity panels, a grey-water recycling system, triple-glazed windows, and a composting toilet. Electricity derived from the solar panels would be stored in a battery array, and rainwater would be collected for domestic use.
The idea is still very much on the drawing board at the moment, but Hullu imagines his design could be implemented as housing or as an eco-resort. He further states that if he gets the investment required to build it, he would also set up a Community Land Trust to ensure affordable housing.
