False Ceiling and L-Box

Our false ceiling and L-box is up. :)But becos of Coris pillar structure, our aircon cannot be placed lower without incurring more aircon trunking tat cannot be covered up, hence hitting the L-box. A opening has to be created too. i reckon its used to allow servicing to be done as it needs to be open in upwards direction. Our HSS opening is boxed up too. Only a small hole is opened up.
