If you need additional help with any other steps such as build over agreements, party wall consent, or finding tradespeople you can trust, we can help you with all of these things, too.

Of course. You can make minor alterations such as glazing, roof type and shell finish at no extra charge. If you want to make more substantial changes to the structure, we will simply quote for the additional costs with the Resi Design team.

Design - £64 per hour inc VAT.

Building Regulations - £108 per hour inc VAT.

Planning Support - £160 per hour inc VAT.

The costs include a measured survey, existing designs, the extension design and ground floor internal configuration. This is everything you need to get to the point of planning permission.

We would highly recommend you also get a CCTV drainage survey, structural engineer, party wall surveyor (if needed), building control approver and a building regulations (BRegs) package.

BRegs, as you will often hear it referred to, are your technical drawings. Think of it like a recipe for baking a cake. BRegs give your builder the guidelines to ensure a building is safe, healthy, and efficient. Any reputable builder will insist on you having them as without them there is a high risk of discovering nasty surprises during the build process which could significantly increase costs. So please be aware of builders who convince you that you don’t need them.

Yes! We can introduce you to nearly all the trade professionals you may need via our Connect service.

As part of our services we will prepare and submit the necessary documents to the local planning authority for approval. During this process we will then act as your agent. This quote does not cover fees payable to the local planning authority. We will guide you on when and how to make this payment., Approval for planning permission or lawful development depends on your local planning authority. Decisions can be overturned by senior council management even after initial approval. When acting as your 'agent,' we don't attend site visits, including those with the planning officer, during or after the application process. We make efforts to follow up on planning submissions to get feedback from the local planning authority. However, we can't guarantee their response, but we'll do our best. If required, additional work carried out by the Resi planning team outside of the scope of this quote will be charged at a pre-agreed rate of £160 per hour inc VAT
