Hello everyone,
I have a few questions to the members of this forum who have constructed homes on 20x30 plots and also to architects who provide plans for the same.
My interest is to know what the actual permissible points are, with the interest that they can be made in plan (meant for approval) itself.

1) What is the maximum FSI for 20x30 plots, if:
-- (a) It faces a 20ft road
-- (b) it faces a 30ft road
I'm assuming the FSI varies in both cases.

2) Almost everywhere I see people constructing wall to wall on 20x30 plots even in residential zones. As per bye-laws is this still a violation (which insists on 1m setback on the right side)?
Has any one had a plan sanctioned which shows wall-to-wall floor plans OR Is everyone violating the norms in this case?
Are they actually utilizing any exceptions to construct wall-to-wall in a legal way?
I also read that if the width is <6m then a side setback is not insisted. In such a case, <6m would mean <18ft or <20ft?

3) What is the minimum width insisted for interior staircase assuming its a single dwelling spanning Stilt+3?
I've read from 0.75m to 1.2m. I dont know which is the correct value.

4) I've seen floor plans where people show toilets or staircases in the setback area abutting the corner plot boundary.
Toilets are generally on rear setback. Closed staircases & wardrobe provisions via cantilever projections even in front setback (on higher floors).
Are such provisions against bye-laws? Can they be shown in a plan meant for approval?

5) On Stilt+GF+2 setup, I've seen people make open staircases and open balconies leading to their entrance in the front/side setbacks.
In many existing homes, on such GF, a cantilever projection open-balcony (open-to-sky) is present over the rear-setback as well (as a utility area).
Is this permissible in the plan for approval? If it is, is such area free from FSI?

This will clear a few more questions which I have.
Thanks in advance

hydroxide,

Please check this link for BBMP BYELAWS document.

Going through that document yourself is better to get answers for #1 & #2

#3 - I think you should consult an agent+BBMP approved architect for this. For me, the BBMP approved architect has shown 2.4mx2.9m but that's an internal starcase.

#4 & #5 - I don't think anything is allowed in the setback area on GF. On higher floors may be cantilever projections are allowed. Better to check with BBMP approved architects.

From my experience its better to consult BBMP agent/architect once your plan is 80-90% finalized. The mistake I did was that I started the BBMP approval process once my plan was 100% done. Even my architect was not 100% sure about several things and we had to modify the plan once the agent/BBMP approved architect got involved...

Thanks Girish for your reply. I had one other question to you. Was your staircase area of 2.4m x 2.9m for a 20x30 plot or a higher area plot. Did your BBMP architect mention if this was the minimum width etc to go for?, because in a 20x30 plot, such area will occupy a quarter of the floor plate. Thanks again for your reply.
