Full planning it is. Prepare yourselves for more questions. 🤠

Thanks for the comments. @Nickfromwales and @Spinny, nearly all of what we wanted to do fitted within permitted development and the reduced form-filling and increased flexibility is appealing. I intended to apply for planning separately for two aspects that where clearly not within permitted development. (The driveway and the front porch). However, it now looks like it might make more sense to get the whole thing covered under a planning application. There is only one neighbour affected and we are planning to speak to them. Their house is on the north side of ours, and their garden wraps around the rear of our garden. (There are trees between our two gardens, but I remember reading somewhere that planners don't consider that.) I have shown the entirety of the boundary to the property below. @torre I understand that planners would review the impact of the attic windows on the new gable end on the neighbours, but how is the new gable and its rear facing windows outside permitted development? Is there something within the roof alterations section that I have missed? How do planners approach the rear-facing windows situation? Many houses have upper floor rear windows that look straight over the neighbour's garden and into their rear windows? We already have rear windows and the extra attic windows on the gable end will have little impact on the neighbour's privacy. All input is appreciated, I've learnt a lot already.

We would like to build a two-storey rear extension under our permitted development rights. However, I am concerned by an existing (presumed original) portion that juts-out at the back of our house. The above image shows the original property looking at the rear elevation. The plan is shown above. The rear elevation is on the left. (The smaller building in the lower left corner is a wooden shed built around 1970) This is what I would like to do. And the proposed plan. (The new outbuilding is single storey.) We are within the curtilage and boundary distance requirements. However, my concern is that the small protrusion at the back of the original house (WC and pantry outlined in red) means that the proposed extension to the main house would have to meet both rear and side extension requirements when considering permitted development rights, [Permitted development rights for householders, pg 23]. This means my proposed extension is too wide. (5.1m allowable half-width, 5.4m extension width). More importantly, side extensions can only be single storey under permitted development. I can see that this is not the first time that this problem has been discussed and I have a few questions: 1. Does this particular arrangement mean that I am missing something and that I can actually build as proposed under PD rights? 2. Are there any small changes that I can make that mean I can build under PD rights? 3. I presume the offending lump on the back is original, but I don't actually know. Could I argue that it might have been an extension? 4. If I have to go through planning, is there anything to indicate that it will, or won't get through?

That approach makes sense. Thank you.

Thanks Nick, This is part of a larger extension project, and I wanted to submit plans to get a lawful development certificate. However, you make a good point about standing a good chance with successful planning with the porch - I could apply for planning for this accept separately after the PD certificate has been issued. (I've decided to move the WC to a small room that we already have inside the house, but a bigger enclosed porch would give us more utility space.) There will be some sort of heating. I've not figured out the floor construction yet. It is currently tiled and I am not sure how thick the concrete is underneath, but I was assuming it would need new footings. I will look into Marmox boards.

The design is getting there now, and I be grateful for some advice about what is covered under permitted development rights. You can see from the image below that the plan is for a rear two-story extension that squares-off the original single-story portion. There is also a small porch that take the total extension to just under 4m from the original two-storey part of the house, but that is only 1.1m from the rearmost wall of the original house. A few questions: 1. As shown, is this covered under permitted development rights? We are well within the curtilage and distance to boundary requirements, but a page on Planning Geek made me concerned that the presence of the original single story part of the house means my proposal is actually a side extension. Does anyone of any experience that helps here? 2. Where is the rear of the house measured from? If it is measured the two story elevation, than the porch cannot be extended much further than shown, but if it is the back of the original single story part of the house, I could in theory extend the porch almost 3m more (I would only actually want to increase the depth of the porch by maybe 1m. 3. The original house is brick and pebble dash. If the extension is brick but with wood cladding that is a similar colour to the existing pebble dash, does that meet the requirements for "similar appearance"?

Thanks for the reply. I have changed the design a bit to fit within permitted development size requirements. To maximise the internal space, It would be better if I could avoid having the inner leaf run around the inside of the pillar. To avoid a thermal bridge, I will add some sort of insulation offset from the pillar, shown above in purple. What are my options here? I realise the thickness shown might be a bit optimistic to maintain an acceptable heat transfer. Also, should I drill and inject a damp-proofing cream into the mortar on the pillars, or would that come with its own problems?

We are hoping to convert an external porch to an internal porch with downstairs toilet. The existing porch has brick columns shown in the image below that contribute to the properties charater and so I'd like to leave them in place and exposed externally. What is the best way to deal with the insulation where the columns are, and what about penetrating and possible rising damp? I've started to sketch the design as shown below. Thoughts and advice backed with evidence and experience would be very welcome. Untitled.svg

The image below shows the property as it is now. We are planning a rear two-story extension; and detached workshop, office and studio.

We are planning an extension to our house and I am looking for advice and guidance. It is a work in progress, but this is how it looks now.
