Extensions

Do I need neighbour's permission to build extension

I live in a small mid terrace with an L shaped back yard and want to build a side return extension (2 x 3m). Most of the surrounding properties have extended but none appear to be side return. I understand I am allowed under PD. I want to rebuild what is currently a shared yard single block wall but will become the extension wall to my property. I plan a single storey as I am unsure if I would be allowed a two storey. The space I intend to extend into would extend from my existing kitchen. Where do I stand on the sunlight argument ? and will I need the neighbour's permission to build even though most properties have extended included the one to my left. Thank You
