Paul and the rest of the Detailed Planning team have been superb from the get-go. As a person who's knowledge in this area is relatively limited, they guided us through the steps of our project particularly helping with the design phase of bringing our thoughts to life and then into drawing. They have been available to us with short notice and are happy to jump onto a video meeting to discuss the project at various points of the process. They've provided expert advice with a relaxed manner and have had a real positive impact on what our home will hopefully look like in 12 months time. I would highly recommend them to others looking for similar advice to us.

We came across Detailed Planning through mutual recommendation. I still remember my first conversation with Paul, this is even before our house purchase has been finalised. The way Paul went through the whole logistics on design and planning immediately put my mind at ease. Paul is able to articulate a rather complex process in simple language, he is methodical and systematic in his approach. Our project was managed by Paul’s fabulous business partner Emily. If you are looking for someone who is professional, super organised, detail orientated, tenacious and hardworking, Emily is the person to go for. Our planning applications (kitchen extension, loft extension and outbuilding/parking) have gone through successfully at the first attempt. This is directly related to Paul and Emily’s vast experience and track record in managing similar scale projects and their knowledge in managing relationships with the planning officers. What also we are very pleased with Detailed Planning is their recommendation with other key vendors such as party wall surveyor, structural engineer, building regulations etc. You can tell they are extremely well connected and networked to help you through from start to finish of any project. My husband and I would definitely highly recommend Detailed Planning as a company, really a breath of fresh air in the industry!

Detailed Planning was hired to design and draw up the plans for our home renovation. The job was quite broad, consisting of both a loft extension and rear extension, as well as internal changes to the ground floor. Prior to meeting with Paul, I had met with numerous other architects but we felt they lacked the build knowledge we wanted and focused purely on design. While we had some ideas of changes we wanted to make to our home, I felt we needed the guidance and considered approach to design which Detailed Planning provided.
I was worried that our rear extension might need to be smaller than we wanted to stay within permitted development but I'm glad we listened to Paul's advice and went ahead with what we wanted. Detailed Planning's expertise really showed as our planning permission was granted faster than expected with no changes needed. Communication with the team has been particularly commendable, especially as I'm undertaking the project on behalf of my parents - one of whom lives across the world with an 8 hour time difference.
Working with Detailed Planning started a few months ago as we were in no rush to get plans ready and we have found them to be dependable. The process has been clear from the start and has made my first home project much easier so far. I wouldn't hesitate to recommend.

Very happy I hired Detailed Planning to draw up the plans for my loft extension and apply for the necessary planning permission. A great team who know exactly what they're doing. I got the design i wanted and local council requirements were met. Given that, planning permission was granted sooner than expected with no changes. Thanks so much!

Commissioned them after a first planning application failed for a single storey rear extension to our house. Tailored a new solution which was initially rejected but then won on appeal.
Good level of experience of this niche area and good value for money.

I am a technical oriented person so I understand the level of professionalism of trades. in a simple term I should say I have no hesitation using this company for any of my future projects and for sure highly recommended this company to anyone looking for a decent architect.
they have done the fantastic planning, drawing and follow ups for me and my family and fulfilled our expectations.
Although my project didn't start due to Covid-19 pandemic but I know in near future when I decide to resume this project I have Detailed Planning as my support next to me at any time and at any stage. I have full confidence on this company.

We have been recommending Paul and Detailed Planning for over a year now, as Party wall surveyors we often get presented with drawings which are lacking in information but working with Paul makes our role alot easier by having detailed drawings to work with. Paul and his team are always on hand to deal with any quires we might have.
Highly recommend.

Paul and Emily at Detailed Planning have been fantastic throughout the project. I wanted to re-model the downstairs of my house to fit in a loo, and refurbish the kitchen. The plans were excellent and all updates were discussed and implemented. I felt in very capable hands and expertly advised. I'd highly recommend Detailed Planning.,

We have worked with Detailed Planning on hundreds of projects and have always found them to be professional, reliable and the quality of their work is extremely high. This helps us greatly when undertaking the structural design work on their projects. I would highly recommend Detailed Planning to any clients who are looking for assistance with Architectural services.

Architect services. Very unhappy with the service provided. Other than creating application form I have received no value for the services availed. There was no advice on how to maximise space and I believe I have spent a lot of money with inadequate value. During the course of the work there was very little involvement, no inclination by the architect to have face to face communication, details of fire planning were never provided until the council and estate permissions had been sought. That had a major impact on the project, one that may have revised the approach for extension had we known the details upfront. Very disappointed with the architect we worked with.

Comment from Detailed Planning Ltd:
Dear Sangeetha,
I’m very disappointed to read this review and it’s sad you feel this way. Due to the approvals required for your project, the process was frustratingly slow for both of us, but I feel that our service always had your interests as priority.
I’m pleased to see that you are near completion and disagree that no valued service has been provided.
I have since tried to contact you about this but have not been successful.
I understand there was a situation where your original builder was cancelled part way through works, and it seems there have been changes since our involvement. We would recommend that this is avoided, as it can cause stress on the project.
To recap how our service unfolded:
We received your enquiry via a recommendation from your builder for a loft conversion.
Before proceeding with the services, you were advised that the ceilings may have to be lowered for the loft conversion in order to have better internal height and you were also aware of the strict policies by the Dulwich Estate for loft conversions which restrict the size. I’ve attached a screen shot for interest.
During the site visit, we also discussed a possible extension and internal changes. However, an application for an extension was carried out in the past and it appears that this was abandoned. On inspection of the drainage at the site visit, I felt it was because of the deep sewer invert which would have meant the ground works would be very costly. We discussed the internal changes and I was happy to offer this proposal within our fee, free of charge.
You then instructed us to proceed with the services, this included:
1.A site measure to produce the existing drawings – we used a laser measure and was on site between 2-3 hours, we took detailed measurements and carried out a photographic schedule
2.We then prepared detailed existing drawings, these included existing floor plans, elevations and sections. I’ve attached screen shots for interest.
3.We then prepared a full set of proposed drawings, these took into consideration your brief and requirements. We also included the changes to the ground floor at no additional fee. I’ve attached screen shots for the proposed drawings for interest.
4.Following review of the design, we contacted the Dulwich Estate to establish if the dormer could be widened. They said the guidance must be strictly followed and there are no negotiations. However, I was not happy with their response and arrange a call with their consulting Architect, we then agreed that the dormer height and width could be slightly increased whilst remaining subordinate.
5.Once you were happy with the design, we progressed with preparing the application to the Dulwich Estate (at no additional fee). Throughout the process, we acted as your agent and was in frequent communication with Dulwich Estate providing them with further drawings and requested information. From our original discussion with Dulwich Estate in October 2015, it took until August 2016 until we received the decision. We were both very disappointed and frustrated that it took 8 months for them to issue the approval, but I was in frequent communication to resolve this for you.
6.Following the decision, we then prepared a planning application to Lambeth Council. Fortunately, the council decided the application within their deadline and they accepted our plans first time.
7.Now that we had approval, we could finally move on with the technical phase which included our building regulation drawings (screen shot attached) and structural calculations. We also advised you on the party wall agreements. To satisfy fire safety, we suggested either installing a fire curtain or protected staircase. In the end you opted for a fire curtain.
8.You then wanted to discuss with us if a shower room would be possible within the loft. I showed you some sketches of where it could go but was worried that there was low head height and it would not work as you expected. I thought it would be useful for you to see the shell of the loft completed before deciding on this.
9.We received building control approval in Feb 2017 and this was in theory the end of our service. However, I was available to answer questions and spoke to the builder on numerous occasions throughout the build to provide additional support. However, since you cancelled the service with the original builder, I understand you employed a new builder and made changes to the design which I was not aware of. Since then, building control advised you that the changes did not meet building control approval.
I’m very disappointed that you felt our service was below your expectations, even after such hard work to get all the approval. I appreciate the process was extremely frustrating for us both due to fact we had to apply to the Estate.
I’m happy that you have now have reached near completion and hope you can start enjoying the new space.

We engaged Detailed Planning this year to prepare drawings and seek local authority planning for the redevelopment of our home from 2 flats into a single dwelling.
We worked with several members of the team and they succeeded in gaining permission from Camden Council much faster than we expected and without any alteration to our proposal.
Their work was exemplary, excellent value and the proof of the process is within the work completed by our builder.
I have no hesitation in recommending their services.

Working with Detailed Planning completely took the hassle out of what would normally be a complicated and stressful building project.
I was dubious that I would obtain planning permission for an 1800's previously extended property.
The Detailed planning teams knowledge & advice completed planning application without a hitch, providing incredibly accurate drawings. They then offered further advice for the steps proceeding & even went as far to provide additional drawings at no extra charge when an unforeseen building snag arose.
I had a very definite idea of what I wanted from an extension but Detailed Plannings architects were able to offer creative alternatives.
Not only did they save me money but also added additional space and features I would never have considered myself.
Worth every penny!

Following a decision to look at a single story extension we started the task of finding a company to assist with plans and planning applications, although Detailed-Planning were not local they were more than happy to assist, the whole process from initial contact to site visit and follow ups has been commendable, a very professional and courteous company which has been a pleasure to deal with. Tyrone and Emily have been extremely helpful in assisting us with this project and I would have no problem in recommending their services to anyone considering the same

I was told by the eng. at another company that £5000 extra would need to be spent to add extra steel vertical struts up from the ground floor to help support the loft conversion construction. Then they then decided that the foundations may not even be strong enough, and they may have to be reinforced, which would have cost £10'000s if necessary! By this time I had enough of their advice and asked Detailed -Planning Ltd. to look into my loft conversion calculations. I told them what the other company had said, and within no time they had a very practical solution
that was simple and elegant, and didn't require the fitting of vertical struts in the ground floor, thereby saving me £5000 in extra building costs. They were brilliant and knowing the local area well ment they already had a lot of the information about the house and how it was built in this area. I can't praise them enough, because when we did have other technical problems they answered the phone strait away and were always polite, efficient and helpful. When I told them about any problem, they found good solutions, sometimes on the same day. Brilliant company!
I will use them in the future. 10/10

I hired Detailed-Planning to produce plans for an extension involving creating a kitchen diner and a larger bedroom. From the beginning they were very professional and had very good ideas to compliment my own ideas. They took care of all the legalities and recommended builders etc.
I was taken to see a previous project which is very unusual but extremely helpful.
They have been exemplary in answering any questions and even met with my neighbours addressing their concerns and allaying any fears they had.
The company have visited on a number of occasions to check on progress and took photographs on a regular basis.
I have recommended them to others as I found their attitude to be very professional but also very human!
