Since the height under the stair is low you will need to lower the floor area if it is already not built by 30 cm and you could use it as a study area , a computer table or an ironing space . The first flight can be covered and used for storage. If the stair is a metal stair you can design an internal courtyard there.

upper floors 3 of ur bedroom's headboards are towards north. Not recommended due to magnetic pull. And two of bedroom toilet do not have ventilation. please look into it. Over all planning could be even more better if you refine it a bit.

Hi Prashant, South-east corner plots are actually not good for residential purpose. It is very good for commercial purposes. But, if the house is built as per Vsstu Shastra, it can reduce the bad effects. 1. The South-East corner has to be built with a separate building like a shop, garage, small temple, E.B meter room, boiler room, separate toilet…etc. 2. Trees like Coconut tree, Neem tree, etc., can be planted in the south-east corner of the plot. 3. The kitchen must be in the south-east corner. There are many more remedies. Ground Floor : Few columns are too close to each other which is not required. As per Vastu, kitchen should be in south-east corner as this plot needs to follow Vastu strictly. A separate garage/security room need to be added to this plan. A portico will form in the north east corner as per the first floor plan which is strictly prohibited as per Vastu in south east corner plots. The planning is OK as per me, but your south east corner plot requires a lot of Vastu considerations. First Floor : If the toilet which in the north can be shifted anywhere else better go for it. In the long run, toilets can have seepage issues, which can spoil your living room roof. Generally, we prefer toilets over toilets and kitchen over kitchen. The basic reason for this is plumbing issues/to minimize the wastage of pipes. Hope this will help. Regards Prity
