ART506 Dissertation 2019. Anthony Gwynne . 47 plasters could not be used in the winter (when this project was planned to commence), and lime based products had delays in curing times compared with cement based products (www.lime.org.uk ). • Listed building consent was submitted and approved subject to the use of natural stone roofing tiles and lime pointing externally. • Upgrading of the fabric to Building Regulation standards- using Approved Documents for guidance • The designer prepared the technical design based on Approved Document L thermal insulation requirements (Figure 14 ), and incorporated planning and LBC conditions into the scheme and discharged the planning and LBC conditions. Works phase and unintended consequences A Building Regulations application was submitted by the designer as a Building Notice instead of a Full Plan’s application (Appendix G). A Building Notice is a simple form of application that can be submitted without the deposit of plans or specification, there is no plan checking and is normally accepted without question. The designer is sent an inspection schedule (Appendix H) which requires the builder to notify building control at certain stages of the works. Once the Building Notice had been accepted the builder started work on site. The builder was recommended by the designer and appointed by the building owner. Under the requirements of the inspection schedule, the builder notified building control of his intention to lay the new concrete floor. Unfortunately, this was the first-time building control became aware of this project and visited the site. At this point in time it become apparent that the building was constructed with solid stone walls that should be upgraded using vapour permeable materials. However, the builder confirmed he had very little experience of using lime or vapour permeable materials and the building was being converted using non-vapour permable materials and insulations as follows, indicated in Figures 19, 20 and 21 : • Ground floor had a polythene damp proof membrane laid over the floor area and returned up the walls, with a 100mm thick concrete slab laid, ready to lay 100mm thick high density polyisocyanurate insulation board, 75mm cement/sand screed and stone flags. • Plastic damp proof membrane tanking system had been fixed to the internal face of the ground floor to prevent damp and a high density polyisocyanurate insulation board was on site ready to line the walls. The plastic lining is shown in Figure 19 .
