The hallmark of FP-VRC lies in its versatility. Serving as a conduit between floors, it obviates the need for extensive construction work, particularly in situations where heavy structural modifications are impractical. Its unique four-post structure not only ensures self-support but also presents the flexibility of installation directly onto the ground. Alternatively, a modest pit depth of 200mm can be incorporated for enhanced accessibility at the entry level, catering to the diverse preferences of homeowners.
