I don't remember which layout this was, but the lighting caught my eye (no pun intended). It seemed a good idea, so I snapped it and present it here as 'an idea that might be useful to someone'.
The bright idea (OK, that pun is intended) is the use of white 'square' guttering to hold and shade the linear fluorescent lights. No carpentry (excepting the supports), no painting, light, durable and reasonably cheap I think too.
