Seeking suggestions particularly for kitchen and bathroom layout in my basic little studio in a remote area (no Ikea, Home Hardware, or other similar stores accessible).

Bought the chinese modular steel frame, foam wall panel unit from someone leaving the island who hadn't erected it yet (was still in container). This means I had no say in the design layout. It came with solar panel systems, and some basic kitchen cabinetry, corian type benchtop, a sink and gas hob & range hood, and tongue and groove bamboo flooring (short by about 5sq metres) .

Came with almost no instructions - just some diagrams not to scale, so has been the largest jigsaw puzzle ever for my father and I who are the ones putting it together with occasional help from tradesmen.

Ended up having to roof over it because we couldn't stop the leaks in the interconnecting foam lined roof panel, but rust had already started and will be a constant struggle. Now we have the structure up, and I want to get it liveable with in our very meagre budget. We have to get the greywater drainage plan signed off by the relevant agencies, so I need to decide kitchen and bathroom layout. It will have a composting toilet since septic systems required in beachfront areas are unaffordable.

I love the views out glass doors that came with it. both the front (4 doors to the sea)

and back (3 doors to the mountain)

.

The kitchen provided was missing parts and got some water damage but is meant to look sort of like this (but no oven is here, and even though the hob is, I think I may leave out the huge range hood):

I've salvaged some of the water damaged cuboards, and now am looking at having it along the wall, but the doors do go right to the edge, so could have the tall pantry one at this end. and the fridge next to it. But there are no interior walls and I have pretty much free space for now.

There is nothing fixed in the interior yet, but I would like flexibility to put a queen size bed either on the back (mountain side) wall just next to the doors or on the front corner by the two windows.

Welcome any ideas for the layout
