Mohammad. I understand your program. You may be lost in the details at the moment. Please do follow and trust the advice given here by all these people. You are about to embark on a reasonably expensive journey. Get professional help with someone who you can sit down at a table and brainstorm with them your ideas and intentions. There are Architects and there are professional building designers who are members of the American Institute of Building Design (AIBD) who are well versed in projects such as yours. I personally love a design challenge. After 38 years designing homes and special use buildings I enjoy this type of challenge the most. I am in Ohio and may not be close to where you are but I am sure with a little investigation you will find the best design professional for you.

Where to go for cheap furniture Goodwill, word of mouth from friends and family, yard sales, and moving sales. Wooden pieces I will buy from anywhere and will dive into a dumpster even, fabric/leather pieces much more picking with. Rugs are easy to clean or have cleaned. Always do the smell test, if you gag run away. You can paint anything, even fabric covered chairs. Get an idea of what you want your space to look like, and feel like. Create idea books in Houzz for each room. This will give you a guide to what you like. Less is more. You don't have to fill every room. Get basics first and everybody has a different idea of basics. Find yours. Put only things that you love in your house, and everything will look great. It will be a home filled with love.

First, I would ask the builder to give you the dimensions of the furniture used in the plan. Since they've already done the legwork-you will know which pieces will fit. Many times folks go the the furniture store and end up with a huge sectional and it over powers the room. Second, just get what you love! You have to live there. Start to create an idea book in Houzz. You'll start to see a pattern. Then just find a sofa like the one in your pic that is in your price range. Just keep repeating until you have all your pieces. Same thing with wall decor (which I would do last). Have fun!

Hello, I jut saw your comment. thanks for the same. Appreciate your suggestion. Could you please help me to get some construction engineer who can help me to design my ground floor which is about 4 ft underground where the floor and ceiling are already there. The side walls are also there. Only thing is the partition wall to be created to make as a single bedroom house. At present on the east side there is a garage and on the north side a room with toilet. We would like to convert this as a proper single bed house. Since I have a very low budget, can you please suggest how to go about it. Thanks and look forward to your advise.
