I,M trying to find out if i built up ,on top on existing rear flat roof
kitchen 14 ftx 12ft ,x10ft height , ie built a bedroom 14x12 ,height 12ft ,Would i need planning permission .this room is at rear of house, would not overlook any neighbours.ie it would not effect anyones privacy.
IT would be built using wood ,with tiles to join onto existing roof .

If you were to build as you outline, what distance would you have, from the new external walls, to the side boundaries (both sides) and to the rear boundary?

Precise measurements of these distances would be required to determine whether or not the proposed first floor extension could be built with or without planning permission.

In addition, aside from the existing (ground floor) kitchen extension, are there any other extensions to the existing (original) house?

[riclad]

HOUSE was built pre 63, at rear ,theres ,a kitchen,and room,extension all wood, that were built, say 1950, house built 1920, classic red brick,terrace,bricks ,mortar,front of house
similar to this
http://www.myhome.ie/residential/bro...blin-7/1749816
so at rear,40total area, per cent of house ,is wood extension .
the new room would be on top of kitchen, approx,
14ft from rear wall.theres a yard a rear ,14ft x 12ft approx,
with concrete ,walls on 3 sides.the room would be built ontop of kitchen,
so distance is the same,eg 14ft from wall ,extension,kitchen to rear wall.
i think you are implying that to build without planning permission
there must be x feet distance each side ,
from new room to boundary wall on the right, and on the left ,
ie you cant build onto boundary walls ,with permission.
OBviously you could build anything, pre 63,
no planning permission needed ,
for existing room, kitchen.

and on the left.
ill post a drawing later to give more info.

[DOCARCH]

If you want to build a first floor extension without planning permission, generally the external/side walls of the proposed extension need to be a min. 0f 2.0 metres from the side boundaries and a min. of 11.0 metres from the rear boundary (if you want to have a window) - anything less than that and you need planning permission.

If the house is terraced or semi D you can only build a max. of 12m2 at first floor level to keep within the exemptions and then thats subject to the criteria as mentioned above by DOCARCH

[riclad]

ok,, say theres no windows ,do i still need planning permission,
As posted before , new build would be about 14ft from rear boundary wall, The right side would be at least 12ft from wall on the right.

[muffler]

The exemptions and conditions for same are all contained here

[riclad]

YOU mean the room could be max height, say 11.99 metres high,
measuring up from the floor,
on the 1st floor.
This is light wood construction, apart from roof tiles, which would be same colour as existing tiles, on rear roof.
I,D be happy to build, it with no windows.

[DOCARCH]

Even though you are only considering a first floor extension, your yard (private open space) could scupper you - you need 25.0 m.sq. private open space - from your measurements it does not sound like you have that space.

Bear in mind all these criteria are to do with exempted development - if you do not comply with the criteria set out - that does not mean you can not or will not get planning permission for what you want to do.

Pretty much the only thing you could use it for then would be a bathroom or extension to an existing bedroom? You need windows to bedrooms to comply with Building Regulations.

What is Exempt Development?
It is possible to extend your home by up to 40sqm to the rear without the permission of the planning authority. quote from extend.ie.
SO in a pre 63 home, where there was 2 extensions,built,
before 1963.
DOES that mean say the 2 old extensions,
take up 20sq metres, i can build in theory another 20sq metres,at the rear.?
i understand the rules re distance to rear, side, boundary walls still apply.
I dont understand ,how building a 1st floor extension,effects the yard,private space,
it doesnt overlook anyone ,or effect any neighbours privacy,in this case.
Is it legal,re building regs, to build a bathroom with no window
?

Yes, but subject to certain criteria - area is not everything - read the link Muffler posted above, then come back.

[rayjdav]

Any extensions pre '63 are not taken into consideration for current rules, as they existed prior to the planning regulations coming into effect.
So if you have extensions pre 63, you can still build 40sqm to the rear, but you must take heed of the conditions attached as per Mufflers link above. If you cant acheive these dimensions or conditions, and you still want to build, then you must apply formally to your LA for Planning Permission.
As DocArch said, just because you dont have the noted dimensions or space, this is not to say that the LA will not grant planning.
Exempt Development basically is something you can build without applying for permission, but you MUST STILL COMPLY with Building Regulations.

I,m reading thru the link posted ,re exempt extensions .
i would intend to comply with building and fire regulations and would get the plans checked by an architect or professional who would be qualified in those areas.
at some point i,ll post a rough plan here,after i read info re exempt extensions.
I,m trying to work out ,is it viable to build a simple 1room extension ,it could be used to enlarge an existing bedroom, or just a tv room.

[rayjdav]

ANYTHING, pre 63 is omitted from your new area calc's. But if the extensions were done since, regardless of the status of the house, then their area's must be deducted from the 40sqm exemption limit, at ground floor level.
