Precedent analysis

The Granor Greenhouse by Wheeler Kearn Architects is the main inspiration for the vertical extension. I believe the idea of a greenhouse is particularly appealing. Greenhouses are passively heated and cooled; thereby making it self-sufficient and environmentaly friendly. It is also an economically viable solution as the structure is lightweight and easily assembled. Additionally, the structure is completely permeable; thereby, making it ideal for the narrative of a beacon, as the view of the rooftop botanical garden would be stunning in the evening when the lights are on.

Application

Detail interpretation

The same principles can be applied to the vertical extension of the proposal. Because the greenhouse is on the roof of the structure, there are no surrounding buildings casting a shadow onto the envelope. The structure is bound to benefit from daylight and passive heating. Passive ventilation strategies can also be easily implemented by creating side windows and opening the reception area space to the top floor (quadruple height space) thus giving an entire building natural ventilation. There are also opportunities to harvest rainwater and use it to sustain the rooftop garden. Solar panels can be incorporated into the green roof for additional self-sufficiency.
