Costs really vary in different areas and they are always changing . You would be best to talk to 3 local contractors who have good reputations and ask them what their building costs are. When you say "interiors" do you mean furniture? Or the interior finishes? The contractors will be able to give you the interior finishes numbers, but you can talk to a few local interior designers for estimates on furnishing a house. Also, ask the contractors about landscaping costs. Do you want a pool or an outdoor patio? Or just planting? Plus the building permit costs in your area. Check with the local building department. Some areas charge school fees.............. It would be great if you could factor in an architect to help you pull all of this together. Also this should be an architect who has great references and is known for working within budgets. Once again, you should ask 2 or 3 for proposals to see how they price their services. It can vary.

Hello MuthuKumar, OPC 43 and OPC53 grade cement are more suitable for residential projects.. You may use Grade 43 for the PCC and RCC work. Once that is done you can use Grade 53 for Plastering and finishing. Make sure adequate curing is done at all stages and do regularly check the age of cement bags. The above suggestion may change based on the the type of construction being done and it shall be considered with your architect or contractor before proceeding.

Hello there, If you don't want to put load on your foundation, why don't you put a pergola of cement/steel/wood instead of a concrete roof slab? You could do a bit of landscaping too and could fully utilise the terrace. Regards, Aurum Ideas and Spaces Bhubaneswar

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.
