CONSERVE

Historic Buildings

A historic area of England, the East coast around the Wash envelops many structures that were built before the inception of Building Act of 1878. As such, any design work should be considered from a sympathetic stand-point so as to avoid deterioration to the fabric of the existing structure.

Tanfield-Johnson provides a range of services aimed at the assesment, conservation and restoration of Historic buildings in the most sympathetic manner possible. These include Site investigations, structural design and specifications.

APPRAISE

Condition Surveys

Tanfield-Johnson provides condition surveys of entire residential and commercial structures, assesing the fabric of a building, areas of deterioration and conditions that may lead to future defects. Our reports can be used to put in place a system of rememdial measures or works to rectify defects and prevent future deterioration.

Historic Structural Assesments

Materials and techniques used in the construction of buildings before the Building Act of 1878 differ considerably from those used in modern buildings. Historic buildings may lack substantial foundations, have no damp proof course and rely on the use of "floating timber" floors, raised above "dirt" by no more than two feet. Applying modern building techniques and materials to such structures can inadventatly introduce rapid decay to the fabric of the building. Our understanding of such historic building practices allows us to investigate and assess such buildings, avoiding the confusion of modern building regulations.
