1st question is what sort of advice?
Is it structural loadings etc? if so is it complicated? If so then a
structural engineeer would be the best one
If it is to do with fitting problems, DPC, cavity etc then a surveyor,
technician, quality builder or even an architect but in general a fully
qualified architect would not be in the least bit interested in your
extremely small problem to him but very large to you. If you know a good
builder and are on good terms with him then I would go down that route for
technicl, fitting type advice
