Hi there, i am starting to renovate my semi-d in Balik Pulau ,Penang. I plan to add a side patio all the way to the back of the house. Front will have slight extension of about 2' to make the living room square. Wall to be built all around house 6' height. Was quoted 6k by contractor's contact for drawings and submitting documents to Mppp. Is this price reasonable? Appreciate all help. Thank you in advance.
