In this video, discover the rules for adding outbuildings, rooflights, porches etc under Permitted Development.
Class C provides permitted development rights for roof alterations that are not covered by Classes A and B.
Class D allows you to build a porch outside any external door of a house, except where the house was created through a change of use.
Class E allows the construction of buildings, enclosures, swimming pools or other types of pool within the curtilage of a house.
Class E also allows the siting of a container used for domestic heating purposes for the storage of oil or liquid petroleum gas.
Class F allows the provision of a hard surface
Class G allows the installation of a chimney, flue or soil pipe on a house.

Love your videos and very informative. Business next to me owns outbuilding in rear of my curtilage. Has access rights only - and share of path - opened business in outbuilding (grrrr). Council say no planing required. She is non-householder and non-resident and rents out the space. I’m an upper flat with 1 below. Confused about flats and permitted development

[@efkor]

Thats a very confused comment. Sounds like a legal problem not PD.

[@stevetaylor1657]

Thanks for the information, please could you tell me the rules for this scenario, we have a searching for brick base, outbuilding which we would like to knock down and make into garden room. What are the rules on existing buildings?

[@efkor]

Your PD allowance covers existing and proposed structures

Hi I am working my way through your videos they are very good, a question on outbuildings if I build a garage at the end of my large garden 2.5 mtrs away from the boundary 2.5 to the eves 4mtr to the ridge can it only be a two sided pitch or can I make it L shaped building so a 90degree turn on the roof
Many thanks
Ian

Thanks for your comment. Theres no restriction on roof shape as long as you comply with all regs

Thank you for the videos, they're great. I have a question though: In the video it says for outbuildings, the maxiumim height is 2.5 or 3M depending on proximity to boundary. However how does this work if you have a multi level garden? We have a 3m wide back garden, after which it drops away at almost 90° for 3.5m, then falls away at 45° for a further 3m in height before levelling out. Thus in total the bottom garden is 6.5m lower than the top garden. We would like to build a garden room half way down at the foot of the first 3.5m drop. The rear of the structure would sit on the ground at the base of the first 3.5m drop, and as the base projects forward would sit on ground screws at the front extending up to create a level platform. But whilst the rear of the structure could easily be within the limit, due to the downward pitch line of the garden, the front section would be higher off the ground directly below it because the ground is falling away at that point. Therefore my question is: in this scenario does the 2.5/3m maximum height requirement basically mean at no point can the structure be higher than 2.5/3m from the ground directly below it at all points of the structure? And is the height determined relative to the neighbour's land? I ask this secondary point to see whether it might be an option to build our ground up with gabions to create a level platform and the therefore stay within the limit relative to 'our' ground, but of course would be higher than the neighbours' ? Please bear in mind the top of the structure would still be lower than the ground floor of the house. Many thanks.

As you have found, PD rules dont cover every scenario, especially where there is sloping land. And where one council might agree with your interpretation, another might not. Have you considered obtaining a Lawful Development Certificate? This costs just £100 and ensures you don’t accidentally build something outside your (council-interpreted) PD rights. As it proves your project was lawful at the point of construction, it also protects you if PD rules ever change.

@@efkor Thanks so much for responding. It would appear then I'm at the mercy of their decisions, which I suspect would be quite strict as they recently refused permission on some very minor alterations my neighbour wanted to make. If they were to refuse, can one appeal PD decisions? Thanks again.

I am proposing a workshop at end of garden exceeding 30m2 and higher than permitted development allows so will need planning permission but am struggling to find what building regulations will actually apply... any ideas?

[@efkor]

Hi Michael, is this useful? www.planningportal.co.uk/applications/building-control-applications/building-control/building-regulations/exemptions-from-building-regulations

[@michaelwalker2998]

@@efkor Thanks for taking time to respond. I will need a strong coffee or 3 to fully understand what may/may not apply to my proposed structure. It will be about 1m from boundary but intend to use metal sips type panels for construction of walls and roof so non combustible and insulated. One part will be partitioned to be be small gym/office rest will be workshop. I think/hope the structure is exempt in terms of foundations needing to be building regs compliant.
