With all building work, the owner of the property (or land) in question is ultimately responsible for complying with the relevant Planning Rules and Building Regulations (regardless of the need to apply for planning permisison and/or building regulations approval or not).
Therefore, failure to comply with the relevant rules will result in the owner being liable for any remedial action (which could go as far as demolition and/or restoration)
The general advice is to always discuss your proposals with the relevant Local Planning Authority and Building Control Service before starting work or to take advice from a Chartered Surveyor familiar with procedures and requirements.
There are also other considerations 'before you start work' such as health and safety requirements and additional permissions that may need to be granted such as rights of way or listed buildings consent.(see also Architectural Services)
