    The structural integrity of CLASP buildings are strong and robust, the design being based on; strong concrete foundations, metal framing supports and concrete cladding give the building a unlimited lifetime timeframe (with small maintenance carried out). It is these design fundamentals of CLASP that can allow buildings to last over a hundred years.
