If the site selected is as per Vaastu, it is fine. Otherwise the very site must be corrected prior to the starting of construction in such a way that there is a reasonable projection of North-East corner. This will be very handy to make the entire shops a bit projecting towards North-East. Such commercial complexes, which satisfy other vaastu principles, will also become popular and would make good profits. Commercial complexes of shopping arcades have to be designed with lot of open area for car. If the parking is in cellar, the building can be designed with little more open area in the North and East than South and West to satisfy Vaastu.

If there is no cellar for parking, a lot of area should be kept open in the North and East for car parking and for green patches. If the plot is facing West or South and more area is left open in the South or West for car parking the owner will run into financial difficulties. In such cases where the plots are facing South or West, it is better that shopping complex is built on the road with minimum open space in South or West. The complex should not be built covering the plot upto the North or East boundary. Instead more open area in the rear i.e. North and East should be left, where car parking, lawns, fountains, etc., should be designed. Pumps and bore wells have to be planned in North and East.

Drinking water in shops has to be kept in North-East.
Show cases have to be avoided in North-East direction; and better in South and West.

Lathe machines are to be installed in South and South-West directions, if some shop is used as a work shop.

Stocks are to be stored in West, South or South-West and South side portions of the shops. Better to have lofts and low roofs towards South and West direction, within the shops.

North-East corner is to be kept with all the sanctity within the shop. In the corner a water tap or a small puja place could be designed. North-East corner should never be used even for a day for storing any kind of materials.
