Hi HN! We're Luke and Heather, founders of boxouse:
https://boxouse.com. We build portable, beautiful(ish), affordable smart homes out of used shipping containers in our West Oakland factory. This began out of our frustration with paying high rent for crappy apartments: we started thinking about our monthly rent in terms of how many shipping containers we could buy (2 per month!). We're particularly interested in using containers as a tool to increase density and affordability; among other things, we're going to deploy containers to people's yards for free, sharing the rent revenue with them. We do all the construction ourselves; more than happy to dig into technical details!
Hire a decent photographer, large sensor, low f number. You'd be surprised what a good camera with a competent person running it will do. Go wide angle.
Your unique selling point should be the thought you put into the layout. Anyone can insulate and sling in some furniture, the real hard part is making the space lovable/liveable. Choose a theme or period, industrial is a good start. You have bamboo flooring, why not use it for the fittings?
o Put beading/moulding around the windows. Its simple and cheap.
o Match the doors and frames to the plywood/cladding
o Change the electrical outlets to metal, anything other than the stock white
o Use industrial light cases, it'll match the industrial look better
o Make sure the stuff you install is straight, and neat, the bed slats are wonky!
o The bamboo flooring looks great make use of it more!
o when taking the photos, think about where the light is coming from, make sure its streaming through the windows making the place look bright
Also, don't give up...
