West side 30ft, east side 30ft. 2. The ground floor contains 2 rooms. First room measures 15tf by 15ft and that is meant for a shop. The shop having one side door to the east while the main shop entrance faces the north side measuring 12ft wide. 3. The backroom, same measurement. 4. The first floor to be developed into a two bedrooms apartment. 5. The stairs to be located along the east side, outside the rooms.
