In this case, the designer and owner designed a closed balcony to improve indoor lighting. The living room balcony is connected, which improves the overall space utilization and transparency, and cleverly achieves space expansion. In addition, considering the frequent strong winds weather condition in Guangdong, ZEKIN specially selected the Chris series of high-end system windows, using high-load-bearing hinges and high-strength high-quality handles to support and reinforce the window structure, further ensuring the load-bearing and safety of the windows. The corners of the window sashes are designed with zinc alloy safety corner guards, which has created a free and safe growth environment for children. The family tea room uses double-layer hollow glass, high-quality sealing strips, and a multi-channel sealing structure design to effectively reduce the acoustic resonance effect. In the kitchen space, the owner uses a medium-narrow aluminum alloy frame with an oversized glass design to effectively improve the lighting and transparency of the kitchen space.
