Hey brother, thank you for asking, To construct this kind of residence there are a lot of factors that will determine the Investment like 'Location', 'Material used', 'Labor cost', and the 'complexity of the design.' Based on the research I did the average cost for this kind of residence in India range from ₹15 - ₹20 lakh. for a 500 sq. ft. area. to prepare a precise investment you would need to consider the 'plot area', 'civil cost', and 'finishing cost.' of the local area _ _ _ _ are bhai, poochhane ke lie dhanyavaad, is tarah ke nivas ka nirman karane ke liye bahut saare karak hain jo 'sthan', 'prayukt samagri', 'shram laagat' aur 'design ki jatilta' jaise nivesh ko nirdharit karenge shodh ke adhar par maine bharat mein is tarah ke nivas kee ausat lagat ₹15 - ₹20 lakh tak kee 500 varg foot kshetra ke liye ek steak nivesh taiyar karne ke liye aapko sthaniya kshetra ya shahar ke 'plot area', 'civil cost' aur 'finishing cost' par vichar karana hoga _ _ _ _ I hope this gives you an idea and answered your question.🙏🏼 _ _ _ _ mujhe aasha hai ki yah aapko ek vichar deta hai aur aapke prashn ka uttar deta hai.🙏🏼
