Permitted Development - Loft Conversions 

One further thing to mention is the cubic volume allowance takes into account other extensions. So if the property has already extended with rear/side extensions that have added 'roof space' (measured from the eaves to the ridge - flat roofs would have technically add nothing) then this will be included in the total cubic volume usage up to that point - even if it doesn't attach to the main roof.

Just to point one thing out that you have missed. The external look has to be in keeping with the original house. I had to do a retrospective planning application because I put grey cladding instead of smooth fibre glass. You can actually submit a permitted development request to your local planning office for a small fee to check what you plan will be covered by PD. I wasn’t aware of this. Plus make sure the builder of the house hasn’t removed PD from the property at the request of the local planning. Something I didn’t know that others should be aware of. Great video though.

Great video. It should also be noted that not all properties have permitted development right under an Article 4, the rights can be removed when the property is built. This catches a lot of people out.

Very informative and very well explained. Thank you.

Really enjoyed your two videos. I’m a property viewing rep so this is really helpful to me to discuss what’s possible with my viewers. Thank you very much.

I'm a retired architect and just wanted to sound a note of caution concerning loft extensions built under permitted development rights. I was once caught out by the principal elevation rule on a property with an original small two storey side extension. This did not appear to visually relate to the principal elevation but was deemed to be part of it by both the planning department and subsequently the appeal inspector. Their decision effectively stopped the project as a proposed hip-to-gable element - essential in this case to enable the staircase to be extended into the loft - was deemed to be in front of the principal elevation and therefore illegal.

Thanks Scott, nice straightforward video. Would it be possible to make one on fireproofing aspects of the escape route from loft conversions, and likely BCO requirements. Also general video on BCO would be good for those with no experience. A getting started video with things like foundation and wall strength checks (how, when, who) would also be of interest. Thanks again.

We had a 2 year battle with our parish council over reinstating 2 dorrmer windows on our hipped roof end,our house was built originally with a second floor in the loft and the hipped end originally had 2 dormers which were damaged by a tree in 1973 and when the roof was repaired they were deleted,some other major changes to the house were made at the same time. I still don't understand why it took so long,as the planned dormers matched the originals and those on the front and rear roof but we have the dormers now. I wouldn't mind so much but they face sideways from the road into a field and overlook nothing but countryside, the nearest house viewed from those windows is about a mile away! Councils work in an odd and inconsistent manner,I have learnt that nothing is a given until they say so.

A well put together and clear explanation for home owners and professionals alike. We are small design and build company in London and enjoyed your presentation.

Useful video. However, the only proper way to establish whether or not you need pp is to submit a Certificate of Lawfulness to your local planning authority, who will give you a written legal determination.

Excellent video. Thanks.

Really love your video, wish i had seen this about 4 months ago. I was doing a project with hip roof and didn’t get into loft cauz of complication of roof shape.

Interesting video if you are thinking of having loft conversion. Thanks.

Very good and useful video, please make more

thanks for posting valuable information

Excellent informative video.

Great video! Keep em coming..

you mean 50 % of house volume for semi , previous extensions are deducted from your allowance & 70% of total volume for detached

Great video, thanks.

Very informative to a layman like me.Thanks

It's about time they scrapped PD. I live in a cul-de-sac and the house at the entrance to the street has done a rear loft extension under PD. They now overlook everyone's gardens and houses within the close. Aside from the lack of privacy the scale and look of the dormer is entirely out of keeping with the style of the other houses. It's as though they have converted the house into an office building.

Excellent values...

That dormer is not PD. It also has to have materials to match the roof-face of the existing property.

Came for the loft conversion, stayed for the animation

1.9m clearance for loft stairs.

Informative video - great sketch up. My house is ‘sideways’ to the road, meaning one gable faces the road with the other facing the garden at the back. Presumably I’m free to put the dormer on either roof slope given that neither of them are at the front of the property?

Really funny golf iron or rescue club very funny ha ha ha ha ha

Spelling error in the summary : "principle elevation" is wrong! It is "principal..."

do you need planning permission to add stairs in the small bedroom?

hey man cool videos can you do a video on the new 2 storey upwards extentions permited ? thanks

Why am I watching this, I got a flat roof

Great videos! This is slightly off topic but I've read that loft conversions aren't possible or are at least extremely difficult on timber frame houses. Is it the case that the timber frame isn't strong enough to take the extra loading of a loft conversion? Thanks.

Hi I have a question regarding the 20cm set back condition detailed in the permitted development for household technical guidance (September 2019) and the High Court case (Waltham Forest London Borough Council v Secretary of State for Communities and Local Government [2013] EWHC 281. In the said case (which is approximately 10 years old) it states that the set back should be measured from the closest point of the projecting eaves (which is the intersection with the wall),rather than from the outer edge of the projecting eaves. The more recent permitted development for household technical guidance (September 2019) states The measurement of 0.2 metres should be made along the original roof slope from the outermost edge of the eaves (the edge of the tiles or slates) to the edge of the enlargement. Any guttering that protrudes beyond the roof slope should not be included in this measurement. If i am reading this, they seem to contradict each other, or is it that the more recent permitted development for household technical guidance (September 2019) has superseded the High Court decision?

what are the laws on converting an attic my house is the very same layout as the video and would reinforcing the floor joists or would a steel need to be fitted to carry the floor as I don't plan on adding any bathroom or shower and what floor would be accepted to be fitted

In the case of a wrap around dormer, do you have to make an entire flat ceiling (levelled) inside or you can keep the pitched roof shape for the remaining ceiling? Thank you

I keep seeing it written that developments should be 2 meters away from the boundary line to avoid planning permission, does this not include dormers?

Thanks for the video very informative, im thinking of converting my loft to a bedroom, what if i want 2 dormers in the front side of the house, what is the maximum sise for dormers allowed for 2 dormers on a semi-detached house? Thanks.

nice REVIT ANIMATION mate

Can you do extending on top of an existing floor extension which is a metre away from neighbours and may block light to side window

hi, can i remove red brick wall fence? it is 3 meter away from road. i would like build one store extra room size 3meter wide and 5.5 meter long, 16.5 square meter, without planning permission. garden door i will not remove, it gonna be separate building with concrete metal bars, stones, red hard bricks, my house semidetached size 9 meter long, 5.5 meter wide, 49.5 square meter. the law says 50% footprint width allowed build without building control, my house wide 5.5meter so i can build 2.75meter wide? or 3 meter will be ok too? thank you

I want to build dormers at the front of my home...I am a bungalow at the end of a close, and do not overlook another property for well over 100 metres, and that property being a bungalow anyway, any advice?

What are the rules on container homes? I have mixed reports from you need planning to put it where you like as it's classed as temporary? Thanks in advance.

I have a 6m x 6m detached garage with a pitched roof, I want to do a loft conversion just as you have done here on the detached house. Would the same rules apply?

Hi all, how do you work out the volume of the proposed dormer to see if it is within the 50 cubic metres

My house is in the middle of an estate and is not on a road at all, does this mean I can have a dormer extension on the front?

Hi, is there a way of finding out whether a property has had its PD rights removed by any previous extensions?

my home is a detached 3 storey victorian and have a half flat roof and half pitched roof. My question is how can I make it all flat?

Thanks, I have 2 questions: 40m3, does this apply only to the dormer or the entire resulting loft space? You said the dormer needs to be offset by 200mm from the eaves; does it also need to be offset on each side of the roof? Thanks!

Quick questions: If the loft space is a bit tight (6ft 1 floor to ridge), is it possible to bring a dormer to above ridge height by 30cm or so. I’ve seen a few example of this locally, just wondering where it would stand with building regulations and also is it a good idea?

☑️☑️I got a degree in civil engineering with no experience... What courses do you recommend to get in this section... Many thanks in advance

Hi, Can I build one storey extension and also have a loft extension on top on a semi detached bungalow? I don't live in any restricted sites..

Do the rules still apply or have they changed.?

which software you were using for animation ?

Sky sports news interruption

What modelling software do you use?

I can here to learn something nothing new learnt!

wth are brits like this limiting so many things😂

Loft coversions look vulgar.

Omg mr boring voice
