Contracted architect 2/2019. Discussed building top of garage; access from garage to flat no1 (above the garage) & another flat (no2) into loft space of main house. Seeing stairwell (access the flat - no2 main house) inside flat (no1) above, means flat (no1) small! But there is loft, height of main building enough for loft conversion as bedroom in flat no1. That agreed. Architect supplied plans for flat (no1) above garage for Planning Application. There after, once approved, because everything else is inside, alterations can be done easily, architect said. Loft conversion flat (no1) did not show in the plans for Planning Application; not required. Planning Application approved 5/2019. 2/2019, contracted FP Group, Luton to quote on specifications & signed contract for building flat (no1) in June/July once Planning was approved. **** Contacted architect AGAIN 6/2019 - for next phase drawings - (flat no2). Discovered when " said he did not have design for staircase to access loft in main house" into flat no2 & said to me "why I did not use his contractor". Architect also said why "you did not contacted me before you started building." I was horrified. Architect asked contact of builder. After architect & builder spoke, builder came back denied he gave me a quote which included above garage loft conversion (flat no1) etc. This was itemised as the first line of builders quote & contract! NEVER again ! One man show.
