Hello kellyi. The living room needs straight, long drapes in a simple pattern, I think. No swags, no tie-backs, no extra anything. I'd look for something with a light, off-white background as the room is a bit heavy with brown, and perhaps a geometric pattern that introduces your favourite colour. It could happily be green, but the room is so neutral it could be anything. Pick up that colour in a couple of throw pillows, which could also be patterned, or plain. On the lighting I think you could probably get better advice from someone else. But I'd also like to suggest big art for your fireplace to hang just a few inches above the mantlepiece. Again something modern, light and bright. Preferably with a touch of brown in it but other colours predominating -- including the curtain colour. I think these are both charming and cheerful, but of course nothing is more about your personal taste than choosing a painting. These are on etsy.com, in the landscapes section.

Seems there are a few who have gone before you and are sharing advice on forums etc. http://www.performanceforums.com/forums/showthread.php?67232513-The-next-project-painting-the-shed-floor http://www.bobvila.com/articles/bob-vila-radio-painting-garage-floors/#.WArj82U7bxA http://www.aussiev8.com.au/members-lounge/46685-painting-your-shed-garage-floor.html

I've used fireplace paint before. Bought from BBQ's Galore. Our fire was black cast iron though. I'd check with the paint manufacturer if you can use it on powder coat. The paint is really smelly (toxic)...seriously, the last thing you'd want is it burning and peeling off because it doesn't adhere to the powder coat.

R u laying boards over the concrete or beside?
