Chris has provided us with an excellent service all through our building works and further assisted us in different planning issues. Great communication and support can't recommend highly enough.Posted on Philip C. JohnsonTrustindex verifies that the original source of the review is Google. Chris provided help for approval of 2 windows for a listed building. The process to final approval turned out to be quite a journey lasting nearly half a year and Chris patiently endured with us to final approval.Posted on Chris ClarkeTrustindex verifies that the original source of the review is Google. Fantastic to work with. Chris knew our budget and helped work with us with what was possible. Chris also picked up from where another architect left us high and dry. Really would recommend Chris for all your projects. EDIT: Since starting the build we have now come across numerous problems with his plans. His drawings were good enough to get through planning, but not for the build. Details were missed, measurements were off, which has led to various delays, overruns and costs to the build. We have had to pay a considerable amount of money for structural purposes which would have been identified by a qualified architect. My advice is avoid using this company, and instead wait and source a proper architect, who can take proper measurements and who can provide the builder with enough detail to make the build less frustrating for everyone. My builder has tried to contact him, but often his responses aim to throw off as much as possible.Posted on christopher pearceTrustindex verifies that the original source of the review is Google. First class service- stuck with it over long delays by locals and planners and achieved successPosted on Robyn TaylorTrustindex verifies that the original source of the review is Google. We first met with Chris from CB Planning to help with a class Q application, (changing some agricultural buildings to residential). We had been told by several architects and agents that it was going to be a real long shot to obtain and not to get our hopes up. However, with Chris’s knowledge and expertise we were not only able to obtain class Q consent, but were encouraged to push for full planning, which we successfully achieved. It truly was a dream come true. We couldn’t have done any of it without Chris, and would, without hesitation, recommend him to anyone considering a building project.Posted on Ben RichardsTrustindex verifies that the original source of the review is Google. Chris has been a huge help in taking our excited ideas and allowing them to come to fruition. Having completed all the necessary forms to proceed through planning, building regulations and a build over with Southern water, Chris is still helping us with our project 2 years into it, well beyond just completing the drawings. Always happy to discuss our project when we reach out, offering his knowledge and advice to navigate a path forwards. Highly recommended
