I think a comfortable distance between the island and the counter is around 42". It seems that you have only 30" between your cook top and the counter. I might be a little too tight. The wall between the entrance and the kitchen could be 4' long instead of 6', you would then be able to move the island a foot which would give you more room between the cook top and the island. Could you switch the location of the toilet and vanity in your dad's bathroom so your enter facing a vanity instead of a toilet which is a lot nicer.

example: winding staircase, source internet Little modification need to be done for entrance lobby opening, where you could accommodate a shoe rack and the complementary vertical wall can act as a amazing entrance decor wall wall in Kerala style heavy color play or texture/wall cladding with brass mural.. by doing this you get space to mount TV unit and a good space for sofa arrangement (make sure sofas are light as the space is less to accommodate baggy sofas), staircase can be made in the shape shown in sketch plan, with marble finish on the foot steps (or as per interiors), space in the bottom of staircase next to master bedroom wall can be utilized for chest of drawers or a tall furniture, make sure the staircase bottom part to be casted smooth in finish.

Hey Rohit, One thing we have learned that it is difficult to convert our weaknesses to strengths, but it is very doable! 42' of living and dining room space could be advantageous! off the top of our heads, here are a few things you could do. Split the space into formal and informal seating areas, basically creating 2 rooms (not counting the dining) in one space Push the dining in the middle of the room, closer to the middle bedroom, and add a swing near the balcony. In case the large size makes it uncomfortable, you can add a partition between the dining and balcony. and design the space in a way that opening the balcony doors, converts your indoors to outdoors, creating the feel of a terrace. lastly, the simplest of solutions would be to add a partition (solid or otherwise) to divide in room into 2 parts, a living space and a dining space! We hope this helps. In case you need Drawings to understand the space and out idea of the space utilization, please feel free to get in touch with us and we would love to work with you!
