Pictures of your dining room and kitchen would be helpful.

I won't bother with lattice, barrels are partially obscured from the street by fencing and if I put it up I would have to work around the lattice in order to turn the valves for water. If I can just make better use of collected water I'll be happy. We are at the end of our growing season so I should be cleaning up the garden and putting it to bed for the winter, just can't seem to get motivated. We had our first frost last week. Usually, our average early frost date is 1 November. I got almost no produce from garden this year, but there is always next year. Chookchook2 I've seen some of those decorative metal panels and they are gorgeous, sure hope your budget will allow you to get some before too long. Most of our state has been on fire for a good part of the summer. The closest is across the river from us and they have been battling it for almost a month. Some friends have had to evacuate repeatedly. We've only been concerned once, a small grass fire on our side of the river on a day we had wind gusts up to 65mph. Fortunately, it was put out quickly. Australia and New Zealand have both sent firefighters to help with the blazes. I can't begin to tell you how appreciative we are. The closest fire was fought for almost a week by local volunteers only as there were no other resources available. They were all on other fires. The Army National Guard (reserve troops) were called out to help with support duties and for the first time ever the federal Department of Natural Resources (DNR) asked for civilian volunteers to help with non firefighting tasks, cutting fire breaks, moving supplies etc.

I think this gray faux wood tile will look very nice with brown carpet. It also will look wonderful in an all white kitchen!

I cant imagine that tiles on concrete will be any colder than concrete alone. But the choice of colour may make a difference to the heat absorption qualities; dark tiles will absorb heat better than light coloured ones.
