The information in this report aims to assist owners of Underdown and Winget houses, or their representatives, to make decisions appropriate to their own particular circumstances. It describes, in Part 1, the defects and deterioration which have been found and the inspections and examinations which may be necessary to determine the structural condition and likely further performance of an individual dwelling. Some possibilities for repair or remedial work are outlined. Part 1 is based on the investigations described in Part 2 which were concerned primarily with the condition of reinforced concrete components. When owners or their representatives are making a full inspection and assessment of Underdown and Winget houses, it will be necessary to look wider than the scope and conclusions of this report.
