Skylight balcony

[alwaysonit]

Essentially a window for a room with a slanted roof that opens both up and out and down and out from the split - becoming a balcony while still standing inside due to the slanted roof. Video here.

Would planning permission be needed for one of these?
And would anybody have a rough estimate of installation cost?

Thanks!

Prices for the units are [broken link removed]. Cost of installation will vary depending on size and roof construction.

They're essentially still a skylight, and they are exempt when placed to the rear. From the SDCC guide:

Planning permission is not required for rooflights or skylights proposed on the rear roofslope of a dwelling or on roofslopes that do not face onto a public street provided that they lie flush with the existing roof slope. In this case, it should be noted that the number and size of rooflights or skylights proposed should not dominate the roofslope - it is recommended that they do not cover more than 20% of the roof slope on which they are located.

In my opinion they are not exempt.
roof lights to the rear are but this is a cabrio product that creates a balcony.
