@DevilDamo Thank you for your advice. Can I start the 3-meter single-story extension build and then apply for consent under (Section 73)?

I didn’t want to start a new topic, so I’m posting my question here. I live in an end-of-terrace property and received planning permission last year for a two-story rear and side extension on one side of the building. The building work hasn’t started yet, but I’m also considering extending the living room by 3 meters under Permitted Development (PD) rights. The living room is adjacent to a neighbouring property. My question is: Can I first build the 3-meter single-story extension under PD rights and then, after a few months, start the larger project that already has planning permission? I’ve checked the planning permission letter, and there’s no mention of PD rights being removed. I’d appreciate any advice or guidance on this.
