Renovations can be pretty unsafe for beautiful furniture, fixtures, fittings and buildings when intrinsic qualities are sometimes destroyed to follow popular style trends. For example: the late 20th century mindless acid stripping and staining of wooden furniture and fittings which destroyed many nice but unfashionable original french varnished surfaces.
Human health and safety is also at risk from renovation, yet should be of paramount consideration. Clearly, renovators should be very sure that they are not just following a trend when renovating as costs can be way too high both to heritage and human health.
