Since the lot you describe is smaller than my open living area, I would suggest looking at some of the "shotgun" house plans around New Orleans,LA. I think you can build up and back and get an interesting home with a loft for space. It can be done, A porch with an entry to a narrow hall at the back might work best for you. Will you plan a courtyard (closed)? or what? What part of the country are you in? What are your local codes?

softyjain, If the windows need to be replaced I recommend looking at fixed steel to maintain the narrow profile of the windows and small window lites. Using fixed instead of operating will be a cost savings if you don't need to open them. Another option for hanging from the ceiling is a decorative light or chandelier. That way you still have light into your ceiling at night. We offer Renaissance solid bronze windows that don't require any finish or finish maintenance. Architects designers love the rose bronze color, which closely matches copper gutters. http://www.houzz.com/projects/152134/Renaissance-Solid-Bronze-Windows---Doors-by-Progressive-Solutions You may also be interested in this ideabook- http://www.houzz.com/ideabooks/18543834/thumbs/Bronze--Copper---Steel-Window-Ideas

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.

Dear Amit, Thanks for working on the same and pointing out the things some of which I have not thought of.I am attaching the main design which was given to me by the builder.I She have worked in the main plan and made some changes as below: -She have clubbed common Bath as per the original plan with the MB to make it bigger,but no option was seen to extend the attach Bath. -I was thinking of keeping fridge at the kitchen and W.M inside the common Bath. -She have suggested sliding door in MB which I can change it. -I haven't thought regarding the position of the TV .You are correct that it will be too far. Can you please suggest how can I utilise the spaces in a better way. -The work which have been done is as below: 1)We have broken the common Bath wall and clubbed it with MB. 2)One wall of the kitchen have been broken to make it a open kitchen. 3)She have changed the location of the main entrance from 4th part of the south ,as I didn't have any option to change the location of the main entrance to other direction .As per her 4th part on the south from right is ok for entrance. 4)Right now the entrance is as per the builder design .We haven't changed it till now.
