Hello dopcam, Anchor bolts have to be mounted on ceiling. If your false ceiling is already done you may have to get a section of it opened and after the work is done it may be closed. Of course after providing for the swing space. Thanks Nitin Cornerstone Designs Bangalore.

Rs 40-60 per Sq ft

Jeco, Price variations do often confuse a home owners. Going a bit off topic, often we have to politely say no to clients who are looking for a fixed cost on day 1. The design evolves over a period. Pricing is extremely sensitive to location and materials selected. For example there are materials that would start from 60 sft to 1000 sft which can be used for this external construction. Unless that material is specified it is difficult to pindown the price. Having said that it should be in the range of 2-5 lakhs in Bangalore. This idea definitely looks good but have you considered that this is a terrace sit out and design and the requirements of porch are completely different. For example you may not want rain water to fall on the cars underneath ? Thanks, Nitin Cornerstone Designs, Bangalore.

On average, you might find prices ranging from $1 to $5 or more per linear foot
