Build Over Agreement

A build over agreement is required if you are building within 3 metres of a public sewer.
If you have opted for full project management, Summit will arrange for any necessary build over agreement on your behalf. We serve London and surrounding areas.

During the survey of your property, Summit will endeavour to find out if you are within 3m of a sewer, and can advise if you are likely to be subject to a build over agreement. Please note that it is not always possible to locate the sewer at the time of the survey. If our surveyor cannot locate the sewer on your survey visit, we recommend that you carry out a CCTV inspection of the sewer prior to submitting the building regulation plans to building control.

Worked with the team at Summit for a single story back extension. They worked quickly and kept us up to date throughout the process. These guys are great and we would highly recommend them!

While exploring the idea of a sunroom, my friends offered a few names of companies in London that are reputed for such jobs. After talking to a few, I came across Summit and contacted them. I don't remember whom I spoke to, but the person understood what I was looking for and explained everything to me in very simple terms. I liked their professionalism and in the manner they responded to my queries. I hope to get Summit's services and would recommend the same to others.

Great working with Eleni & the team. Really pleased with the drawing designs and the advice offered regarding the local authority planning permission. Looking forward to the rest of the process and hopefully starting the build soon!

I have had an amazing experience with Summit Architecture. They have been attentive from beginning to end and I am so pleased with my new extension. Great team, I’d definitely use them again.

After looking for someone to do our kitchen extension plans, we found Summit by using Google and found they had good reviews, similar to what we were after. After our initial call with Oliver, we had a site visit, then decided to go with them as they were just right for our budget. At all stages throughout the process, we didn't have any issues. We just needed them to get us to planning, but in the end decided to go for the Building Regulations + Structural package too. Looking to build in April, can't wait!
