Hi anna_cannon, having a plan drawn is a good start, you might want to put the dimension on the plan as well just to help others know exactly where everything is. This is what I think works given the information I have. Not sure if you how much renovation you are looking at and whether you need both doors to the back but I kept them just in case. Basically I have grouped similar functions together such as (freezer, pantry) (linen, washer/dryer, sink), and (bench, coat hanging close to the doors in the back) ... all the plumbing stays the same to keep cost down. Hope this gives you an idea on what's possible in your multi-functional space.

I just think it needs more bright white trim around the windows and the fence painted also white. Going round to the back addition, I would paint the timber boards the color of the stucco, trim white and get some great deck furniture and lighting.

Oh so cool you noticed that we're trying to achieve a french country/industrial look or did we write that somewhere? I've attached some other photos of a bedroom and the foyer (of those we've taken so far), but are absolutely open to suggestions on a "beachy" feel as well or instead of. Although because its a beach house we don't want to go over board on expense and hence keeping what we already have, and just adding personality to it, if you get what we mean. Kingsize Black upholstered headboard to come in that bedroom.

A very simple layout keeping the floor space within the kitchen, the WIP takes up a lot of space with not much gain, The broom cupboard could be moved to the Laundry/entrance, narrow. If the wall has been bumped out to the eaves on the deck side giving an extra 300 depth to the kitchen you could make the island 2700 x 1200 and all drawers. The wall of narrow pantry will hold all pantry needs and more, no deep cupboards to dig into. cheers
