design dilemma ?

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.

also plz suggest elivation plan

Hi Tanzil. Greetings, The plan is looking very generous. Nothing to criticize but a little thinking could make a real good plan for egl. 1) The hall could accomodate the dining area as well. 2) A single stair is sufficient enough to fulfill the requirements. depending upon where it is placed. 3) A lounge on the first floor would add the charm to the upper floor and a large balcony may be if possible. 4) Some vegetation in the interior could make it lively. 5) I f a small courtyard if not a hindrance into the central area can make it more inclined towards nature since it would be good for light and ventilation. There are a lot of other small things possible depending upon the requirements and the structural probability.There doesnt seem to be the column and beam overlay over the plan which would be also helpful in designing. Thanks and regards Riddhish
