Hi Stargirl! I look forward to working with you! I have a couple of questions for you.
First, it will really help me if I have a picture of what you are looking for to go by. I have some pics of homes that I found and thought might be appropriate. I know the colors aren't going to be right, easy to fix. And I know some of them aren't on stilts, but that can be fixed to. Below are four different homes for you to check out. Let me know what you think.
This next one below has floor plans too. A real bonus for me! I thought instead of the sitting area on the second floor, we could make it into the fourth bedroom. Make sure you scroll down the page so you can see the floor plans.
This next one is too dark for a beach house, but color is easy to change. I liked the actual floor plan for this one though. I would not use any windows on the porch and just let it be open to the deck. Again if you scroll down you will see how the layout of the floors will go. It looks like a nice design.
At this time the only other question I had was in your request where you asked:
"Master Suite with en suite bathroom- Bedroom, Vanity table, bookshelf, small tv and comfy seating also a room with arch to go that is furnished but empty"
Did you want a separate room for future use? If I know what you want to use it for, I will know how big to build it.
I think that's all I have for you right now. I hope some of it is helpful. Please remember I can build any kind of home on stilts, I just want an idea of what you're looking for. If you have any pictures for me, I will be happy to take a look.
