Oh, Ii wish I had a photo of ours here at work- we LOVE our new closet. We built ourselves from a section of our bedroom, and then used organizers from Easy Closets. You measure yourself, then design it online with their software. Before you order, a specialist calls you to go over everything and make sure that you have the correct measurements, talk to you about the options you added, give pointers, and stress that you can call cust svc any time.
Looks like Closet Maid stuff, but WAY better quality. The customer service was fantastic!! It's a little pricey (I think about 10-15% more than Elfa from Container store maybe) but again, better quality than anything you'll get from Home Depot or another big box store.
We started with a pretty big walk-in space with LOTS of shelves and a few drawers so it took 2 days to install. A "regular" reach in closet wouldnt take more than 3/4 of a day at most I'd assume.
Tips- read the directions! (this goes for any of those solid looking systems) read them several times, so you're not referring to the details before every screw you put in the wall.
Use a good 4 foot or bigger level for the track on the wall. totally necessary.
get help if you have to carry boxes upstairs. We scheduled our delivery for a Friday, and when UPS came with 24 boxes- well... it was insane!
we actually left space to slide our dressers into sections under some shelves- looks awesome, and saves a ton of space in our bedroom (we have IKEA Malm dressers in the 3 drawer- perfect for the things that cant just sit out on a shelf, and way cheaper than adding those expensive closet system drawers.) so, I guess that's another tip- you could slide in simple dressers instead of paying a ton for drawers with the systems.
sorry, I get really excited when I talk about this project- it's one of our real accomplishments. Dare I say, a closet changed our life. we actually dont mind putting away mountains of clean laundry now!
ETA: as a reference- we had Closets by Design and California Closets come in and give us an estimate (and so we could use their ideas- after all, they're the experts with space planning!) each company came in around $3000 for our project, then with "discounts" came to maybe $2500 including install. We got our whole thing done, including buying some new wooden hangers for DH for about $950. again, this was a pretty BIG space IMO- 4 walls of stuff, 11x9 room. your experience may vary
