Exterior Design is a Singapore roofing and zip blind contractor, so the overhead cover and the side screening can be planned for the same space. You do not need to know every product name before speaking to us. Tell us how you want to use the space, what works already and what needs to change. For a condo balcony, start with ZipNice zip blinds for side screening and compare WPC or aluminium decking for the floor. You can enquire about either service on its own.
