Hire an Architect for the House designs and Building Permits. Habang hinihintay po ung Building Permit approval, send inquiries sa mga kakilalang Engineer's and referred Contractors for the detailed estimated costs based on the design and specifications provided by the Architect. Architects normally asks a percentage on the estimated project costs for their designs pero you can negotiate na lump sum na lang (with an agreed 1 or 2 rounds of revisions) on their design plus costs of building permit preparations.
