(c) in the case of any Class B(d) development—
(i) the height of the original building would be exceeded;
(ii) the cubic content of the original building would be exceeded by more than 25% or, in the case of any building on article 2(3) land, by more than 10%, or

Interpretation of Class B

B.3 For the purposes of Class B(a), “electric line” has the meaning given by section 64(1) of the Electricity Act 1989 (interpretation etc. of Part 1).

B.4 For the purposes of Class B(b)—

“electrical plant” has the meaning given by section 64(1) to that Act; and

“electronic communications line” means a line which forms part of an electronic communications apparatus, (and both line and electronic communications apparatus have the meaning given in paragraph 5 of the electronic communications code set out in Schedule 3A to the Communications Act 2003 (the electronic communications code)).

B.5 For the purposes of Class B(d), (e) and (f), the land of the holder of a licence under section 6(1) of the Electricity Act 1989 (licensing of supply etc.) is treated as operational land if it would be operational land within section 263 of the Act (meaning of “operational land”) if such licence holders were statutory undertakers for the purpose of that section.
