Just received a (large) bill from our architect for work on getting our project as far as planning permission, including a re drawing of part of it. Work would have been charged (RIBA rates) as a % of total build cost but we have terminated the project as we have sold the house. Architect has therefore invoiced for "time" but the bill is not itemised i.e x hours @ £x per hour. Is this normal, it doesn't seem right just to have a lump sum?
