It is advisable not to round off corners. Although North-East corner sites are good, it should be ensured that the North-East corner is not rounded off.

South-East or North-West corners when rounded off may not be considered as a serious Vastu defect.

However, South-West corner when rounded off is considered as a Vastu defect.

Also, it should be ensured that the North-East and South-West corners are not chambered. Other corners if chambered are not considered as serious Vastu defect.
