Arch Design Planning Drawings for Second Storey Extension

I am seeking an experienced architectural designer or drafter to create updated planning drawings for my property. The project involves adding a second storey above the existing single-storey side extension. I already have the original plans and will provide these as a reference.

The deliverables should include detailed architectural drawings suitable for planning approval submission. Knowledge of local planning regulations and building codes is a plus. Please provide examples of similar projects you have completed. UK Based
