Debbie was a great asset to our planning application. She made the process stress free with fast responses and a thorough application. Debbie is genuinely interested in the projects she supports and really lovely to work with. I would highly recommend DJM Planning. We have already got her working on another new project.

Debbie is at pains to fully understand what you need and quick to respond. I go to her instead of a big firm every time I need planning help

Debbie successfully helped me get planning permission for demolishing and rebuilding an agricultural barn in the SDNP (South Downs National Park).

In my experience she was:
1. Efficient – She gave clear timelines that she kept to and chivvied me along, this resulted in the application being completed on time. She also helped coordinate with other professionals involved in the process.
2. Communicated very well – She replied to emails quickly, clearly and fully without unnecessary terminology
3. Accurate and Thorough – She seemed to know the planning literature of the SDNP and was quick to research aspects which she was unsure of.
5. Helped save costs – She helped me avoid paying for surveys and reports that were not needed
6. Post application – She was happy to fight my corner after the application was submitted and a couple of misguided objections were made.
7. Post application approval – she helped with understanding the conditions and requirements as well as suggesting next steps to get work underway.

I would definitely recommend her and will certainly use her for any future planning projects I have.

Following a failed planning application for our house renovation, we appointed Debbie to review our application and to make recommendation on how best to proceed with amendment of our plans in order to obtain planning permission. From the outset, Debbie took time to understand our objectives for the family home and subsequently provided extremely clear advice on options that we could consider. Working with an architect recommended by Debbie, the renovation proposals were amended resulting it a significantly improved layout and design from the original application. Debbie wrote a detailed and thorough Planning and Access Statement to accompany the revised planning application and once submitted, supported us with regular updates and drafting of responses during the consultation period. We are delighted to have obtained planning permission and can attribute this success to the calm and professional planning services from Debbie. We would thoroughly recommend anyone to seek advice from Debbie on any aspects of planning for house extensions and renovations.

DJM Planning has assisted us on multiple applications over the last decade. Some were complex and others involved listed buildings. All of our planning applications have been successful. Debbie Marriage is incisive, efficient, fast, professional and a true expert in her field. She is easy to work and to understand. We have also found DJM Planning to be far less expensive than the big planning partnerships and companies we used previously. I would not hesitate to seek advice and services from DJM in future and strongly recommend its high quality services.
