Chris Fox

VERY GOOD SERVICE, listened to my requirements, suggested alternatives and finally improved my own ideas. I found Ashley very helpful, accommodating even at late hours via email. I love my new design which is in final stages of build. The ability to visualize which is a provided service is very worthwhile to be able to see the full picture rather than a flat drawing is very useful. Very good service would defiantly use and recommend if you want a professional design with helpful service and all options detailed.

Ashley came to my property recently to discuss the prospect of having a garage conversion to maximise the space. He clearly and professionally outlined all of the issues with regards to doing this through Permitted Development – enabling me to come to an informed decision. His knowledge and professionalism put me at complete ease, once we are ready to proceed with the planning drawings, ASC Design Services will be the ones for us! Thank you again, Ashley.
