Can I extend over 3 Meters?

Definitely get in touch with your planning department they will help you look at any remaining permitted development but I think it's highly unlikely you'd get another three metres.

Just cos you need planning permission doesn't mean you won't be granted it. The officer will look things like proximity to neighbours (privacy and overshadowing), whether the extension matches the existing property etc. An officer at the council can give you a better idea if there are any special local considerations/policies which you might not readily find on the net.

It's important to recognise that as well as the usual dimensional limits, you are also limited by the proportion of the land you wish to extend onto. This includes the addition of outbuildings and existing extensions. If this exceeds 50% usage, you will be unlikely to get approval. A typical example might be:

Area of site: 100 sq. m.
Foot print of original building: 30 sq. m.
Foot print of existing extension: 10 sq. m.
TOTAL: 40 sq. m.

This would mean you would not be able to add an extension that exceeds 10 sq. m. (bringing you up to 50 sq. m., or 50%).

Actually, the original house is not included in the 50% figure. See Class A of the GPDO - the relevant part states (my underlining):
"A.1 Development is not permitted by Class A if—
(a) as a result of the works, the total area of ground covered by buildings within the curtilage of the dwellinghouse (other than the original dwellinghouse) would exceed 50% of the total area of the curtilage (excluding the ground area of the original dwellinghouse);"

As others have said, the 3 metres depth applies beyond the original rear wall only, so you can't keep adding 3 metres after 3 metres...! Your extension therefore needs planning permission from your Council, which may or may not be granted - absolutely impossible to say, as it depends on the circumstances of your site. You must live in a semi or terraced property (as detached houses can extend up to 4m as PD) - so a 5 to 6 metres deep extension could be quite overbearing when viewed from a neighbouring property, although this depends how tall it is, how the neighbouring property is arranged, how near the boundary it is... etc...

I'm only gutted because I missed it.

Sorry to the original poster, I mis-understood the reg's.
