Tuen Mun Siu Lun Government Complex is a compact development promoting efficiency and sustainable living.  In order to utilize the scarce land resource, it aims at providing a seamless integration of public and recreational facilities within a single building.

The building mass is basically divided into two main parts with a connecting open-air communal atrium at podium which links up the streets by open stairs, lifts and escalators.  Setback and overhangs are added strategically along the streets to provide a sheltered pedestrian linkage.

Passive design measures including full height low-E curtain wall, vertical fins, overhang, vertical greening, dynamic glass system, peripheral maintenance buffer zone are employed in the envelope to reduce heat gain and glare, mitigate external noises and maintain a comfortable environment. Renewable energy and rainwater harvesting system are implemented to conserve water and energy consumption effectively.
