Hire an architect to help you or find a contractor who has a design build service and who is very experienced with your type of project..... It's not a good idea on a project this large to use a chain store .... Also, make sure that whoever you hire works with your budget.

where do u stay... if ur really interested in changing ur kitchen in a spacious manner.. pls consult us for the same.. i will make more use of space with necessary electronics gadgets to be placed along with other necessary food items... Because whatever is the square feet we get in kitchen.. the fridge space and the sink space is dead to use, sink below space will be used for storing dustbin and fennel bottles,etc to store.. etc.. and if u dont have space for washing machine then that also will be used in kitchen if there is no space anywhere.. so basically make a list of ur requirement for anyone to work on it, so that they will give their best ideas on it..

The local contractor working in your area will know all about the extensions permissible by DDA. You just need to match the exteriors with the existing elevation of the building.

hi! it depends on your laminated on the shutter, I suggest play around with light wooden texture laminate and white in the entire kitchen. keep the entrance panel in light wooden laminate. attaching some pics for your reference of the general colour scheme that you can follow
