We have used Detailed Planning to help design and obtain planning for our single story extension converting our one... bedroom flat to a two bed. We have found them to be extremely helpful, communicating the process and how things work throughout. We were particularly happy with their ability to negotiate our extension depth with the planning office, resulting in 3.5 metres instead of the permitted 3m, which was crucial for our space to work. We look forward to working with them for the rest of the project.read more

Paul & Emily are fantastic, they have done everything from start to finish for our planning permission and technical... drawings and the quality of their work is very high (I guess it is in the name - detailed!)They have been patient with all our design changes, provided lots of advice, walked us through the process of who to engage with, when etc. and were always responsive and helpful when we have questions both via email and phone. This is our first major project and we are doing a loft conversion and remodelling the entire house so to have this support has been invaluable and well worth the money.We actually found them on trust a trader and obtained a few other quotes, DP was the most reasonable price wise, had the right qualifications, good reviews and a big plus was their well evidenced portfolio of work & experience in the area. It was a no brainier and they really have delivered beyond our expectations, most things have also been done via emails and zoom calls so the flexibility was there which really worked for us, would recommend them to anyone!read more

Detailed Planning were recommended to me by a friend. We found their prices very reasonable so instructed them to draw... up plans for our extension.Right from their initial visit and all the way through to the finished plans we could not have asked for better service.Paul and Emily were always very easy to get hold of, which I'm told is not the case for all architects.

They even sorted our build over agreement for our manhole to be moved.They work extremely well with their recommended engineer, surveyor and building control company to deliver a very good package.Thank you Paul, Emily and everyone at Detailed Planning.
