Ordnance survey map ref. No.

    Hi this might be a silly question for some but doing a planning permission by my self for a small garden room (yes I need planning permission) got all the plans elevations etc. done most of the form filled out and stuck od this as I can't find the answer anywhere.

    I got the map from OSI but where on the map do I find Ordnance survey map ref. Number and grid reference if available. Is this just my order number and Centre coordinates ITM in the top right corner?

    Not your order number. The map likely has "Sheet number 12-345" or similar printed on it.

    You will find the information near the Ordnance Survey logo.

    The O S map reference number is on the map as 'Map Sheets'

    The co-ordinates are given as 'Centre Coordinates' and then 'ITM (ITM - transverse mercator, which is a type of map projection): followed by two sets of of six digit numbers'.

    Dont forget to state the map scale and outline maps, site plans etc as detailed on the application form.

    You may, probably will, need to provide contiguous elevation; yes even for rear extension/shed. At least thats been my experience.

    One more silly question but how do you actually pay the fee? Is it possible to pay at the time of getting the application to the council building

    They will have a cash / payments office where you can pay in person or alternatively ring said office and pay by card.

    What council?

    most allow you to dip the application in, then go to the payments office, get receipt and include said receipt with the application.

    Co Meath thanks all! heading to council tomorrow to drop it off was just wondering if it had to be paid online somehow before hand.

    Hi all,

    So first try wasn't successful but it wasn't bad 4 points raised.

    3 points are silly things like I put my name in Newspaper notice but mine + wifes in site notice so easy fix.

    Last one is with drawings and I am having trouble finding out what do they exactly need so they are asking "drawings to show finished floor levels of the proposed structure". Is there any kind soul that can share a drawing showing finished floor levels so I get an idea what I need to draw.

    Basically they want to see how much higher or lower the shed will be in relation to adjoining properties particularly your own house. The difference in levels is always taken based on finished floors. You need to either find a bench mark or establish a TBM (temp bench mark) of your own and then take a couple of levels, ie, existing finished floor level of your house and floor levels of adjoining houses and then establish the proposed floor level of the shed.

    If you can get your hands on a dumpy level or get someone to do it for you it is simple enough. Simplest way is take the first level from the centre of the road opposite your house and then on the floor of your house and if there are other houses within about 30 metres you would probably be well advised to show their finished floor levels also.
