    Svetlana Pinaitiene of SEP Design provided excellent detailed drawings and advice regarding the planning consent application for a single story extension. She took trouble to guide me through the intricacies of both the building design and also the planning application. Her approach was always highly professional and she was always ready to answer any particular questions I had about the design process.
