I never thought I'd say this, but you need to SLOW DOWN! We can't keep up with you! I might end up permanently living in the garage with all these projects to do!

I love furniture like this, however, we have hurky heater registers all over our house. How do I utilize such awesome furniture as this when I have to "mind the gap" between the furniture and the wall? Do you have any ideas?

Wow! One Million hits?! That is awesome! I just discovered your site a couple of weeks ago. It is perfect timing, too, because we just bought a new home and we'd love to build some of your furniture and put all the money we save into building a shop! We prefer Lowes to Home Depot. But, I gotta give Home Depot some credit for inspiring me to make up this "joke" to be said upon seeing a lady who is scantily clad in an unflattering manner: "Girl, where'd you get that outfit? Ho Depot??" I suppose it could also be "Howes??" but I think I'll stick with "Ho Depot". :)

Love love love your blog!

Ana, your blog is fantastic. We're in the beginnings of rebuilding our house after a major fire, and I'll be pouring over your plans like a maniac when the time comes to add furniture! Thank you for sharing your gift.

I've read that you can put things over cold air return vents if the vent is still able to get enough air. Although many sites recommend against it in general.

I can't find the site I found the formula for makings sure you get enough air on. But I think you needed the same area of air that the vent takes in open.

With this plan you could probably solve this by leaving off the bottom piece and if that still isn't enough raising the bottom shelf higher.

I think the best types of furniture to put over them would be something with the long legs, like the bailey console, or something that could straddle it, like the puzzle bookcase.

I love that secretary desk! Dream come true. But it'd be better with a wide shelf above the desk. I'm too short to peek into those drawers!

Thank you thank you! Not so much for these (which like you said are pretty darn simple) but for the hope of the secretary desk. I have been dreaming of that, but not even with the pottery barn outlet nearby can I justify the price!!!!

My to do list of your projects just keeps getting longer and longer. I have actually stopped bookmarking them now because I figure I want to make just about everything you post, so one bookmark to your blog pretty much says it all!

I have a question about bookcases. We have quite a few in our livingroom of the cheapo walmart variety. They are *full* of books and I find that after not too long, all the shelves are sagging in the middle. Are there any tips to making one's own bookshelves in a way to avoid that problem? (Getting rid of the books is not an option) :) Or is it just a given that it will be better because it's made from better materials?

Thanks Dustin, that is a cool calculator! I had to bookmark it! Looks like we could get away with 45 lbs per shelf to be under the .09 human eye factor.

Love how this caculator will also factor in any trim or edging on the shelf! Thanks for sharing.

Hello Ana, I just wanted to tell you that the cut list has a typo. The 15 1/2" trim pieces in the cut list should be 16 12".

Thank you for you designs.

Made this yesterday. Be aware the cut list measurements are wrong for the side trim pieces. On the cut list it says 15 1/2” but down in the steps the engineer schematic shows 16 1/2. Even that was too long on mine. Recommend clamping front trim on flush first then cut to fit side trim then mount front trim. Super flush that way. Also we used 1x16 glued panel instead of cutting plywood. Otherwise easy build. Kids and wife love it.
