Excellent individualised architectural services, to a very high standard.

Excellent individualised architectural services, to a very high standard. We kept changing our minds about the remit which required several re-dos of the plans over 2 years, which architect Richard Roberts, was happy to do. We also had potential planning issues which Richard resolved. We appreciated all the hassle being removed.
