Plans2permission in London
Claimed extensive experience but failed to deliver repeatedly. Plans weren't submitted when he claimed that they had. Lied repeatedly about the status. Same with building notice; tried leaving work items out of the building control application to avoid oversight for the builder he brought to the project.
He also introduced us to a builder, and one he provided assurances about, who turned out a fraud (took the money and left the site in a dangerous state). Mr David McKenna takes a cut from the builder that he doesn't declare even though he claims to be representing his client's interests. He had no interest in assisting with resolving the matter with the builder so we had to sort out the house on an urgent basis and will also have to deal with litigation.
I can only hope that, if you decide to go ahead with business relationship with McKenna, that you get everything in writing including dates. Always have building control informed and DO NOT handover ANY money unless building inspector and you have had a chat and spec written down.
I didn't have a great experience with this company. I failed planning permission the first time around having been told that my plans would be sufficient. I then had issues once the building works had started. I had to do the bulk of the work myself. More of a designer and certainly not an architect. What was a very simple job took almost a year to get to the point where I was happy.
