Architect Job - Ramsgate South, KZN, 4285

The addition of a master bedroom with an en suite to an existing house. The house is on a slope, and the bedroom will need a stairway leading up from below as well as a balcony. The room should have large glass sliding doors that open up onto the balcony. I would like an estimate on the total cost, including the plan drawing and construction of the main structure, plumbing for the bathroom, etc. Excluding finishings such as flooring and built in cupboards. The building is a double story, and the extension will be on the ground floor. It should have a flat roof which will be used as a patio that can be accessed from the first floor.
