@Cornerstone design studio: Apologies for making big post; thought that more info will help. @Rupal ji, If it sounds like I dont need any changes; my apologies for that. Let me put it in short,"I am looking for options that give modern facilities without leaving good things from old charm/ comforts. " Thanks for the straight forward comments. I shall try to edit my original post to make it simpler and that looks open to new ideas.

Please Read, 1) Following are the photos of my Mumbai apartment (10th floor) kitchen. Water heater and water purifier were already (haphazardly) installed by my contractor before I came to occupy the apartment. Answer : u can shift the purifier above sink , inside the cabinet which will be made by carpenter. 2) We now have to install cabinets above the counter. ( you can ) no problem. 3) I want to get the PNG gas pipes installed to replace the existing cylinders. Answer : This work you can do after carpentry work. 4) When I saw other homes it appears I not only need pipes but some ghastly looking meters/ valves etc. Answer : meter will be hidden inside above cabinet toward right side and pipes will be inside the hob side counter will transfer through the balcony wall to meter again. 1) The gas pipes will come from the wall next to the balcony doors. The sink is just next to this wall. Will it be possible to install the pipes and meters below the cooking counter or is that not practical? - - Don't know what are all the practical considerations. Safety, access to meter to take readings, location of the sink? ). everything is possible.. 2) If under the counter installation is not practical, where should the pipes and other boxes/meters go? as mentioned above.. 3) Is there any practical solution to clean up the wall with water purifier and heater? (please note the kitchen has a 6" thick beam on the top of the wall above the counter, also 6" think pillars one in the corner and the other large one near the microwave as shown. Additionally it has a protrusion on the ceiling, probably this houses the drain for the apartment above me. ( for above apartment kitchen nahani trap chamber it is... )
