Long Shin Estate is located at Au Tau, Yuen Long, and was formerly occupied by Au Tau departmental Quarters. The development consists of three site specific blocks with retail facilities including a supermarket, a cafeteria, a convenience store, a self-service bank, a village square, a basketball court, community farm, community gardens, play areas and landscape terraces provide altogether 1207 domestic flats.

To optimize the site potential, the village square at the North end of the site and the landscape terrace; and the external staircase and the stepped planters along the slope at the East part of the site are designed based on the existing topography in order to maintain the natural site profile. The village square which is opened up to the Yau Shin Street provides an open space for leisure and festive activities. Pedestrian and vehicular traffic flow within the site are segregated as far as practicable. Refuse collection facilities are located at the far southern corner to minimize nuisance to tenants.
