Loft Conversion Planning Permission in
Cranleigh (Surrey)
A rear dormer loft conversion in Cranleigh is usually permitted development. A front dormer almost always isn’t. Combine the two, or add a hip-to-gable extension, and the picture gets genuinely mixed. We work out exactly what your Cranleigh project actually needs before you commit to anything.

Volume limits for Cranleigh loft conversions are calculated cumulatively – any previous roof extensions count toward your allowance, meaning a property that’s already had work done may have little or none of its 40-50 cubic metre limit left. This catches a genuine number of Cranleigh homeowners off guard.
Add in the 20cm setback rule, the ridge height restriction, and the front-versus-rear dormer distinction, and a quick online guide simply can’t give you a reliable answer. Checking properly, roof by roof, is the only way to actually know.
A loft conversion in Cranleigh isn’t automatically permitted development just because most are – we check your specific volume allowance, dormer position, and conservation status first.

How We Help in Cranleigh (Surrey)
Every Cranleigh loft case opens with a proper check against the actual conditions – volume, ridge height, the setback distance, front-or-rear positioning – not a generic assumption about lofts in general.
What follows is shaped entirely by that check – sometimes nothing further’s needed for Cranleigh, sometimes a full application, prepared properly either way.
If a Cranleigh loft genuinely needs a submitted application, we don’t disappear afterward – council queries get handled directly and you’re kept in the loop as things progress.
Why Cranleigh Homeowners Start With A Desktop Study
Loft rules trip people up in Cranleigh precisely because the front-versus-rear distinction is so easy to miss. A design that’s fine at the back can be an automatic refusal at the front, and we catch that before it costs you anything.
What we recommend for a Cranleigh loft reflects your actual roof, not a sales target. Where permitted development genuinely applies, that’s the answer you get, plainly stated.
Loft designs in Cranleigh rarely fit neatly into one category once you look closely. Rather than forcing a single answer, we go element by element and tell you exactly where each part of the design actually sits.

Loft Conversion Planning Permission FAQs for Cranleigh
How much roof space can I add without planning permission in Cranleigh?
It’s 40m³ (terraced) or 50m³ (detached/semi-detached) nationally, though your Cranleigh property’s actual remaining allowance depends on any previous roof works, which our desktop study checks.
Can I add a front dormer without planning permission in Cranleigh?
Front dormers in Cranleigh generally need planning permission because they affect how the house looks from the street, while rear dormers are usually covered without needing one at all.
Does my dormer need to be set back from the roof edge in Cranleigh?
Yes – any dormer relying on permitted development has to sit at least 20 centimetres back from the original eaves, a rule that’s the same in Cranleigh as it is right across the country.
Does conservation area status affect my loft’s permitted development rights?
It usually does – being inside a conservation area in Cranleigh tends to remove or narrow the permitted development route for dormers, pushing more projects toward needing a full application.
Is Building Regulations separate from planning for lofts in Cranleigh?
Yes – Building Regulations approval is a completely separate, mandatory process from planning permission, required for every Cranleigh loft conversion regardless of whether planning was needed.
Is the desktop study free for Cranleigh loft conversions?
The Cranleigh desktop study won’t cost you anything – you’ll have a clear answer on your loft conversion before there’s ever a fee on the table.
