A few from horchow.

You need to have a proper analysis done on this....you have asked legitimate questions however this requires further information around context. Answers to what it will cost will be determined by the solution and the question here is what is the logical solution for you....adding upper floors to/within existing buildings will be surprisingly expensive. For what you've described overall (a typical "expansion to existing" brief) over two/split levels with alterations and additions touching the kitchen, bathrooms I'm thinking an easy $400K which then as oklouise suggested throws up the question of whether a complete new build is a logical option/alternative. It depends upon where you are, what the existing house quality is and ultimately what you want to spend.....designers/architects will vary in cost anywhere from 5-15% depending on who, what and how much service extent you engage......perhaps start with a preliminary enquiry with some local designers/architects and start the conversation/building information/advice...good luck :) PD

Just a few inspiration photos for you, I guess you have to choose wisely living in the tropics, keeping it simple could look beautiful, gorgeous bedding, bedside tables, lamps or even pendants, a large rug under the bed could look gorgeous and of course bring some of the fabulous tropical plants in to complete the picture

would much rather buy an old home in original condition than one that has been renovated to "add value" for future sale...apart from making sure that we keep a home in safe, clean and good working order we renovate for our own comfort and convenience as new owners and tenants will inevitable want/need something different
