Build Over Agreements

A build over agreement is necessary when your extension or conversion takes place near a public sewer.

It essentially confirms that the foundations of your new construction have given sufficient clearance from the sewer and that access will still be possible if the need arises.

This is another document that can make the sale of your property much easier as it proves that all building work has followed the correct regulations.

We can guide you through the process of obtaining a build over agreement and make sure you comply with all of the necessary requirements.

Excellent service. Paul is very thorough and took his time to make his decisions and explain them to me. He is friendly and helpful and has a ‘can do’ attitude.

Via Checkatrade

Would definitely recommend for any detailed drawings required, we got them in late in the day to provide building regs drawings, were really efficient in completing within the required timescales and went into a lot of detail to make sure everything was right.

I felt in very capable hands and expertly advised. I’d highly recommend Detailed Planning. Our new loft conversion has maximised the space available to us.

Why Choose Us?

Understanding Your Project Goals

When we begin, we’ll take time to understand your brief, you may also have ideas of how the end product will look. We’ll take this into consideration but also consider costs, planning constraints and build ability. There’s no point designing something that can’t be built!

Striving to Create Quality Spaces

Our number one goal is to create spaces that meet requirements and go beyond the expectations of our clients. We love to hear that our clients are enjoying their new home and this gives us the energy to go on.

Believe In Quality Design for Everyone

Good design should not be limited to some Architects only. We are here to provide excellent architectural environments to all, at a more realistic cost compared with some architect fees.

Pushing Technical Detail

Every project is unique and ensuring it is buildable should be considered from the outset. Should we provide technical drawings, we’ll make sure risks on site are reduced by considering all parts of your project. This should lead to overall cost savings and minimised delays.

High Planning Success Rate

We never take on a project where the principle of the development seems unlikely to be approved. During the design, we’ll use our knowledge and check planning policies to give your application the best chance of success. We have worked with many authorities and understand how planning applications are decided.

Flexible Design Approach

We are not fixed to one design style; therefore we can be used for realist extension design to ultra contemporary. We will listen to your brief and design a bespoke extension meeting your needs.

Want to talk about your project? We will always check your enquiry to ensure there is a reasonable chance of success.

Our quotes are free and we can provide free office consultations should your project be viable.

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

I hired Detailed Planning for the design of my loft extension along with the corresponding planning permission... application. Absolutely brilliant service.They know exactly what they're doing. They were open to my design changes whilst keeping a sharp eye on local council requirements. I'm so pleased - planning permission was granted sooner than expected with no changes. Thanks so much!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 answered every query we had and solved every issue that we encountered during the planning and party wall agreements with minimal fuss and in good time. 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. We can't wait for our extension to be completed.read more
