Technical design for replacement historic architectural terracotta balcony

Ingram Consultancy were commissioned to complete the RIBA Stage 4 Technical design for replacing a historic terracotta balcony. Unfortunately the balcony was in poor condition with extensive cracking, localised collapse and decay caused by corroded embedded structural steelwork and expansion of clinker concrete infill. It is hoped that some of the original undamaged terracotta can be saved but significant replacement with new terracotta is anticipated. Proposals were developed to replace the balcony replicating original details using lime construction mortars rather than cement mortars and clinker concrete. Planning Permission has just been granted for the proposed works which is a historic building of local interest within a conservation area and within the setting of adjacent listed buildings.
