Are you Sure?
MPL buildings have a natural timber finish on
both the internal and external walls. Meaning
no wet trades including plastering /rendering
/painting are required. This saves time as
there is no need to wait for curing / drying.
It also has a posive impact on Health and
Safety, particularly in the context of COSHH.
