Questions about Duplex (G+1) house plans

What is a G+1 duplex house?

A house of two floors: the ground floor plus one floor above, joined by an internal staircase, used by one family.

Where should the staircase go in a duplex?

Vastu prefers the south, west or south-west of the house, climbing clockwise. Keep it out of the north-east and away from the centre of the house.

Which rooms go upstairs in an Indian duplex?

Usually the master bedroom and the other bedrooms with their toilets, often with a family lounge and a balcony. One bedroom often stays downstairs for elders.

Can I change one of these plans?

Yes. Open any plan in VARAIPADAM to change the plot size, facing or rooms. It draws five new layouts, and you can move rooms, view the house in 3D and download PDF, DXF and IFC files free.
