While going in for construction of a house, one should keep a few things in mind. These include keeping the length, breadth and height of rooms in accordance with the standards of Vaastu Shastra. Else, the entire construction is considered to have architectural defects. Observation and a keen eye can keep untoward incidents at bay. A room’s height should be kept either equal or more than its breadth. The living room should be airy and properly illuminated to provide a cool, calm and composed ambience. Its height should not be less than 11 feet. It is also not necessary to build all rooms with the same height. Today, duplexes are in. For that matter, a porch, garage or verandah can be constructed with average or lesser height as compared to the other rooms. If additional rooms are required, they can be constructed just above the porch, garage or the verandah with a low ceiling. A loft can be constructed over the bathroom and the store-room which can be used as another storage area. But the height of the loft cannot be less than 4ft. R.C.C roofing is common today. The height-length-breadth of R.C.C pillars and beam can be kept as per your choice.
