Changing garage roof: PP required?

[Welfarite]

If a garage attached to bungalow is converted to a bedroom (garage door replaced by window and flat roof replaced by apex roof (level with house roof)), is PP required?

Yes, you do need planning.

May be not...

Generally, you will not need planning permission for:

Converting a garage attached to the rear or side of the house to domestic use so long as it has a floor area of less than 40 square metres. Building a garage at the back or side of a house so long as it does not extend out in front of the building line of the house and does not exceed four metres in height (if it has a tiled/slated pitched roof) or three metres (if it has any other roof type). This building will be exempt from planning permission once the floor area is limited to 25 square metres. Garages or sheds to the side of the house must match the finish of the house and may not be lived in, used for commercial purposes or for keeping pigs, poultry, pigeons, ponies or horses.

You will require Planning (basically) if the alterations have an effect on the front elevation.

I presume raising the roof will be visible from the front and that the garage door is located on the front - in which case you will require Planning.

It may require Planning for other reasons also (size above 40 sq.m. etc.), so if you still consider that you do not require Planning, you might add additional information to your post.
