The thought of trying to obtain planning permission for a granny annexe might sound complicated but with our planning service, there is little to no work for you to worry about.
When you choose iHUS to build your granny annexe, our planning permission service is automatically included. Our in-house planning specialist will apply for planning permission and liaise with the relevant authorities on your behalf.
Our unique dual application approach means that you have the best chance of gaining approval, right from the start.
Our preferred method of obtaining planning permission is a Householder Application (1). However, we submit the same plans under the Caravan Act (2), so that should any objections be raised, we have a ‘safety net’. This dual-approach ensures that the planning stage is no longer than necessary, and that building works can start as soon as possible.
Most Householder Applications are decided under ‘delegated authority’, where the case ofﬁcer and the LPA management team will make the decision; it’s quite rare for a full planning committee to be involved in the decision.
Your LPA will have their own adopted planning policies and guidance, meaning that no two applications are the same. And whilst there are national guidelines in place, each LPA has its own specific local adopted policies.
In rare circumstances, one or more specialist surveys may be required to support the application, including: arboricultural (tree), ecological (wildlife), topographical (ground levels), ﬂood risk assessments, archaeological surveys, or a heritage report if you live in a listed building. All of these involve a separate fee payable to the specialist company undertaking the survey.
If your main property is in a conservation area, national park, Green Belt, site of special scientific interest, or area of outstanding natural beauty, the LPA conservation ofﬁcer will be involved and can inﬂuence what can be built and how it looks.
A planning notice is issued when an application is successful; it will always have several conditions attached that must be adhered to. The notice may also be issued with
‘pre-commencement’ conditions, in this instance, these conditions must be ofﬁcially discharged before works can start, which will incur small fees.
Our planning expert will work closely with your case ofﬁcer during the planning process to give your application the best chance of being approved. However, if your application is refused, we will review the reasons for refusal and advise on next steps. As a Householder Application is our preferred form of permission to build, we usually recommend that an a mended application is submitted or that the decision is appealed.
Should a Householder Application be unsuccessful, we will fall back to the Caravan Act to obtain permission to build. There are three tests that a mobile home must pass to comply with the Act;
• Maximum dimensions
• Method of construction
All our annexes can be built to achieve these criteria meaning that permission to build your annexe will be achieved one way or another. Your LPA will issue a Certiﬁcate of Lawfulness (COL) should there be no objections. For detailed information on the Caravan Act, please refer to our separate document.
We can’t use permitted development as an option; it doesn’t work for annexes and is intended for outbuildings such as a home ofﬁce. Normal residential uses, such as separate self-contained accommodation or the use of an outbuilding for primary living accommodation such as a bedroom, bathroom, or kitchen fails the permitted development criteria. Permitted development also has severe restrictions on external eaves heights, making internal ceiling heights very low.
PWC Ltd, a Government approved Building Control company, inspect all of our work to ensure it meets/exceeds the standards set by Building Regulations.
Initially, we will prepare and submit the application to your LPA. Once validated (which can take up to four weeks), the planning application process takes eight weeks. Here’s how it works…
Public Consultation: your LPA will write to the statutory consultess, this includes; neighbours, Parish Council (if you have one), Ward Councillors, Highways and Water Agency asking for their comments on the application. Any objections will be logged during this period, most LPA’s won’t accept comments after this stage.
An LPA case ofﬁcer will look after your application up to its decision date (known as the ‘target decision date’) at the end of the 8-week period, within this time the officer we more than likely conduct a site visit.
Throughout the process, our planning expert will engage with your case ofﬁcer to address any concerns and ensure that the application has the best chances of being successful. Any changes required by your LPA will be fully discussed with you prior to them being agreed with the LPA.
Of course, there are obstacles that can delay this process; usually planning objections or a specialist survey request. This means that the timeline isn’t set in stone, rather an example of the process for most of our customers.
