Eligibility assessment

Find out where your property stands.

Around five minutes. The questions are the ones a planning officer would ask, in the order they matter. Where you do not know an answer, say so — an honest “not sure” is more useful to us than a guess, and several of these are things we can check for you.

About you

About you

So we can reply. We need one way of contacting you.

The property

The property

The house the annexe would belong to.

Is the property listed?
Is it in a conservation area, National Park or other designated area?
Has the property had planning refusals or enforcement action?
Where it would go

Where it would go

Position decides more than almost anything else in these cases.

Is that land currently used as domestic garden?
Is it inside the property’s registered title?
Who will live there

Who will live there

Ancillary use is a question about the household.

Shared meals, care arrangements, comings and goings — whatever is true.

Would the annexe ever be let or sold separately?
Would it have its own postal address?
Would it share the driveway and parking with the house?
The unit

The unit

If you have not chosen one yet, say so — it is common.

Are permanent foundations proposed?

Doesn’t fit a form?

A unit already on site, planning history, land that’s genuinely arguable, or a household that needs explaining — just write to us in your own words.

What happens to your answers
