No, Building Regulations approval is a separate matter from obtaining Planning Permission for your work. Any planning permission approval does not mean that the building complies with the Building Regulations and you will have to take a separate Building Regulation Approval from your Local Authority.

No-The Planning fee and Building Regulation fees made payable to the Local Authority are in addition to our fees.It should be noted that the Council fees varies and is dependant upon the type of proposal. We will advise you of the costs in writing prior to making the submissions. Planning is usually £150.00 where the application relates to one dwelling house.Certificate of Lawful Permitted Development is usually half the amount that would be payable in respect of an application for planning permission for similar works. Building Regulation fees vary from £100.00 onwards based on the type of construction proposed.

Once your application has been accepted and validated by the Local Planning Authority, you should receive a formal decision within 8 weeks. Unfortunately Plan B Architecture has no control over the process once the application has been submitted.  However, as your agents we do chase the Local Authority on your behalf to ensure that the application process runs smoothly and we get a timely outcome.
The process for obtaining Building Regulations approvals takes approximately five to six weeks. At Plan B Architecture we usually submit Building Regulation drawings after planning has been granted so that we are sure of the final approved design. It’s only at the client’s request that we submit a Building Regulation application while the Planning application process is ongoing. Being realistic you should allow a minimum of 3 months to obtain both sets of approvals from your local authority.

In a planning application ‘Supporting Documentation’ is usually submitted. In the majority of cases such documentation is a mandatory requirement of your Local Planning Authority (LPA). This will typically consist of location plan, site and other plans, and a design and access statement. It may also include photographs. We are able to provide all of these documents to support your application.

You will need to apply for Planning Permission to extend your property if:

• the volume of the house would increase by more than 10% or 50m3 (whichever is greater) for  terraced properties.
• the volume of the house would increase by more than 15% or 70m3 (whichever is greater) for any other house type
• you live in a conservation area, National park or Area of Outstanding Natural Beauty
• the extension is closer to any highway than any part of the original house (a footpath is also classed as a highway)
• the extension is higher then the roof of the original house or is over 4m high (pitched roof) or 3m high (flat roof)
• you are using over half of your external garden space
• the building is a Listed Building

These are only general rules for when you will need to apply for Planning Permission, and each project should be looked at individually. We would always advise seeking written confirmation that your development does not require Planning Permission from the Local Authority.Even if you have had no previous extensions, here are some examples of the type of extensions that in most cases need planning permission, to give you an idea:

• A dormer window in the roof of your house facing the road;
• A two story extension;
• A extension to the front of your house, or to the side if it faces a road.

Plan B Architecture has a significant experience in doing flat conversions .Kindly contact us for more information.
