从杂乱无序的历史街区到社区共享、历史叠合的城市里弄体验空间“买点小菜,喝杯咖啡再回家!”这是居住在武夷路街区附近的一位奶奶的日常生活。更新后的武夷路320街区给周围人的生活带来了很大的改变,成为年轻人、老年人共享的社区邻里中心。项目位于上海市长宁区“中山公园—愚园路—定西路”重点区域内,愚园路风貌保护区的边界处。历史在地块内留下了丰厚的建筑遗迹,同时也造成了无序堆砌的空间现状、较差的可达性与极低的可识别性,低能级的功能业态已无法跟上武夷路所处高密度中心城区的发展势头。

本项目是山东省首个按照“城市森林花园住宅模式”建设并获得成功的高品质人居社区。项目位于淄博市新区,房宁路以东、汇英路以北,由8栋高层住宅及配套设施组成,于2019年开工建设,目前已全部竣工交付。本项目建成后,较好地实现了前期的设计构想,取得了积极的社会评价,对推广和提升高品质住宅设计发挥了积极的示范作用。伴随着不断加速的城市化进程,中国的城市住宅越来越呈现出高层、高强、高密的特征,虽然提高了人均居住面积,也改善了居住条件,但人居环境越来越远离自然的趋势,违背了人类渴望接近土地、亲近自然的天性。
