Build a two story with a garage under the top story. It will have to be long and narrow lot is not wide. 4 bedrm s will be tight, looks like you only have rm for about 1200 sq ft incl garage. Or you could put front door on side behind garage and stairs inside to go up to bedrooms and bath rooms. Have a small bathroom downstairs. With living area and kitchen, with dining area.

Photos of the current front yard would be helpful.

Thanks Emmeline & Najeebah for your replies. Its a beautiful cinnamon tree. Najeebah, its a well growing tree..I would like to retain it at the current spot and have the living room adjoining it. According to the house plan, there would be only 4'depth from the wall to the main house. N since we live in a tropical region, i would not want the tree to be fully indoor. Mosquitoes & other small insects could find their way into the living area during the monsoon season. How can i show its beauty?Pls advise

Hello there, Please mention the directions and width of the naksha. My suggestion would be to go with an open plan 1 BHK layout in the ground floor and a 3 BHK first floor. As for the elevation, you could replace the existing stairwell with a spiral staircase and slatted wood shades to provide a shade structure to the front elevation. Also, you could replace the exisitng tiles with ACP/ stone tiles which will entirely transform the hosue. The boundary wall also needs to be lowered a little bit to provide adequate ventilation. Geometric MS grills/ jaali could compensate security concerns.
