Hello
My residential building was initially measured at around 4500 Sq ft which included the basement and carporch. Both the portions were later exempted on appeal to the tahasildar. But now also it is measuring to 3060 sq. ft which attracts luxury tax.
But on enquiry , it was mentioned at your site that for the open spaces /balcanies which has got at least one side open to interior or exterior part; the floor area has to be calculated only half.
Is this a valid finding?
How can we substantiate the same?
In my building, there is a courtyard which has got an opening even in the roof. On the first floor there is a common floor around this courtyard and the floor is terminated by hand rails.
Could the above omission be related to my sitiation?
Hope the matter is not too confused.

@Anoob- The Kerala Building Rules have been amended since this Blog Post in 2008. Please check with your Local Authorities regarding the latest circular on Plinth Area Calculation.
I have constructed a small house of about 82.08 Sq. Mtr. plinth area on a plot of about 157 Sq. Mtrs. (3.9 Cents) in Palakkad. The building plan has been approved and the open space to the road-facing side is 1.50 Mtrs., rear side which has a peculiar shape has 1.20 Mtrs., The other two sides have 3.00 Mtrs. and 2.00 Mtrs. open space. The construction has been completed with a 0.60 Mtrs. sunshade all around the building. The Municipality, acting on an objection filed by my brother-in-law (whose intention is only to cause trouble due to family problems) has sent a notice to me to demolish 13.39 Mtrs. of the sunshade from the rear and one side (where the open space is 2.0 Mtrs.). This pertains to the sunshade built other than over the window/door openings of the building. Please let me know what provisions are available legally for me to retain the building without resorting to demolition.
