Kai Tak Development on 3 Muk Chui Street is the URA's first ever self-developed housing estate with focuses on building community, sustainability, modest and practical design.  It comprises three 23-storey residential towers, an elderly friendly low-rise residential block, and a retail block.

Multiple levels of communal spaces encourage community building and enhance connections and communication.  Central courtyard is infused with community rooms, children’s play, tai-chi area and urban farm; low rise block rooftop garden provides green space for passive use and pleasant view to higher units; the Roof Clubhouse has a walking track sheltered by a covered walkway, barbecue area and multi-purpose rooftop pavilions.  Combination of activities promotes communal and healthy life style.  Through interplay of indoor and outdoor spaces, the architecture connects its occupants to their new environment.

One of the challenges was the ventilation of the site. This is in line with the Kai Tak urban design framework as residential developments are required to be podium free to enhance natural ventilation to the pedestrian zone. A Non-Building-Area of 15m between 煥然壹居 and the adjacent site was established.  The ventilating slots in the building design are adopted to further enhance the ventilation to Station Square immediately to our north west.

The community roof is linked by an outdoor walking track under the covered walkaway to take full advantage of natural ventilation.  The community spaces are designed with nodes and niches in the public areas.

On the low rise block, there is a sitting-out area with more planting to minimize heat island effect to the surrounding flats and to offer a more pleasant view. There are Tai Chi area and an urban farm located along the wind corridor on the ground floor plus a children play area to the north under the shade of the highrise block. Overall, there is about 30% greening for the whole site and about 20% greening of all the roof.
