Comments (17)Hi all, Thank you so much for your posts and ideas. I really appreciate it! Well 6 years have passed and we still haven’t made any structural changes as we started a family instead! But we think we’re ready to make some changes now (just when its become more expensive than ever to do structural works!) A few things I forgot to mention in my original post is that the roof is a butterfly/London roof so its not a traditional pitched roof and would be expensive to make convert it. Plus we had to unexpectedly replace the entite roof this year because it was causing problems and didn’t have the time to think about a conversion due to the urgency 😫. The front door is next to the lounge (floor plan is upside down 🙃) I think we’re thinking of a ground floor extension now but ideally i’d love to separate out the 3rd bedroom so it has its own entrance and possibly make it bigger. The third bedroom is at a split level from the 2nd bedroom ie you have to go down 3 steps. But the roof above the 3rd bedroom is pitched and i’m wondering if its possible to extend into it and make it a study/4th bedroom. The pesky stairs still seem to be a problem! RE: John Botham thanks for your advice to be cautious as the layout differs so greatly to other properties on the street. Any advice, ideas or similar problems solved very much appreciated! many thanks SJ...See MoreWould you build a flat roof or vaulted roof extension?
Comments (10)I think a flat roof with a terrace above would be amazing! Flat room materials have really moved on and such good quality now. Or you could do a flat roof with skylight or roof lanterns which will give lots of light. My sister has done this. Her extension is flat roofed and it looks really smart. Also I think if the extension is no higher than 2.5m it can come under permitted development? There are other criteria but your local council planning portal should have all the info you need. Pitched roofs would be more expensive. My garage cost £15,000 but with a pitched roof and tiles it would have been nearer £25,000 and I would have needed planning permission. Here’s some ideas for you...See MoreRoof Terrace planning permission
Comments (7)From a purely commercial point of view, I'd try to shop it to any of the other leaseholders in the block. If they're not all bedsits, there's quite probably interest ... I don't know how you got hold of a property of this kind. But it's a block of flats - and therefore, in all likelihood, leasehold. Which means planning permission alone doesn't buy you anything. You need freeholder approval as well, and that, given you're turning "airspace" into living space, affects the terms of your lease and is quite probably chargeable (the freeholder has to grant a new lease), not just solicitor costs but a downpayment to the freeholder (as a "new flat" is created). You're also likely ending up as (paying) contributor to the building's property management. Then, you need party wall consent; at the very least, the owner of the flat below, but possibly also others aside (because of, say, overshadowing and noise, or structural implications). It can be a maze to navigate this even for a "nornal" extension to a leasehold flat. Don't count on "knowing the other owners" either; it's fascinating to watch what "a little envy" can do. So "commercial" advice, flog it to someone in the building - you'll save yourself so much hassle. "secondary commercial" advice, at least get _all_ the consent paperwork (neighbours, freeholder) in writing before you apply for planning. And "ternary" commercial advice, again before you file the planning application, speak to Kensington's planning advice service, https://www.rbkc.gov.uk/planning-and-building-control/planning-applications/planning-advice-service about the proposal. Given the value of "housing" of any kind in the borough, they may even be inclined, but if you surprise them with a "Daily Mail headline proposal", your idea will be seen a lot less favourable. I suspect you'll have to put a lot of work in to "pull this off" (it is, as other's said, a "snowball in hell" type proposal). Good luck, you'll need it....See MoreRachael Kendrick
