Outdated technology like underfloor convectors and ceiling fan coils are impractical, irrationally placed, and have limited accessibility.
Ceiling space is lost to engineering systems, ventilation ducts, ceiling fan coils, ceiling diffusers, grilles, and light fixtures that take up about 500 mm of valuable space. Slow construction and quality concerns are consequences of disjointed systems and methods, and onsite construction has limited quality assurance.
