Finishing the basement

Since I've determined that the garage is no longer big enough for my woodworking passions (such as they are), I decided to make some use of our basement, since it is hardly being used at all right now. It gives me lots of room in a relatively year-round friendly environment.

Here is the basement as it currently is being used:

The blue dots are metal columns.

Clearly there's a lot of room to use. But we've had some plans for parts of this basement already, though they are a long way off. Some things are unmoveable, such as where the bathroom roughin is (because of pipes sticking up through the floor) and where the bedroom will go (because of the 1 window). The other thing oft dreamed about (by me) is a theather, and there seemed a natural "notch" in the back wall of the basement to fit one in, free of any columns.

I have no idea what a "standard" theater size is. I guess if we expected to entertain maybe 6 adults at most (or equivalent in kids).

This is the layout we had kind of always envisioned having. Then I took the area left over near the walkout door and made that my woodworking shop.

There's some problems I see right off the bat. First, my wife had wanted a wetbar down there, with a very small counter and a sink. That sink would have to be on the same wall as the bathroom sink, as that's where the drain is. Second, the workshop seems worryingly small to me, especially given the doors and the need to keep that an open walkway. I can put all my tools on wheels, but that still seems a small area for table saw, drill press, bandsaw, router table and any future tools. I also have a very heavy and useful table 8' X 3' on wheels that would probably be hard pressed to fit in that area too.

So we played around with things a bit more and came up with this:

The size of the woodworking shop is arbitrary...I could move that wall out as far as I want. But I like the idea of leaving an area open for various uses or general crafting.

The bathroom gets some more room and now there's room for a wetbar and cabinets in the corner outside the bathroom door. The theater shrinks about 2 ft, and now there's a support post (the blue circle) in the room. I don't know how that will affect where the projector can go...I'd guess it would have to go in front of that, which puts it that much closer to the wall. I haven't checked specs to see the ratio of distance from wall/screen size.

So that's what we've considered so far. I'd be happy to have any input you can give on things I might be forgetting, or on your experiences/thoughts about threater size. And from the woodworkers, is that a decent size (either plan)?

Thanks for any suggestions!
 
The theater viewing distance is based on your desired screen size. There are lots of calculators on the net, here is one. You should also look at projectors in your price range and see what their throw limits are for your desired screen size. And my last thought is you might consider doing away with a separate theater and just put a drop down screen in your main room.
 
In my old home the basement media center / big screen occupied about 1/3 of the total living space. I also like the idea of the separate theater room.
 
If you're going for a "Theater in the home" rather than a "Home theater" like I am - then you're going to want to check out the THX standards on the subject. Screen sizes are supposed to be way bigger than most would think. That column in the middle of your theater *might* cause huge issues for you if you try to go with a large screen size to meet the THX specs. Another note about theaters, it is a huge benifit to keep your couches in the center of the room (or no more that 2/3rd back). This lets you do a 7.1 (or more) setup. If the couches are slammed against the wall like your diagram shows in version #2, you won't have acceptable sound imaging - especially for the price you'll be spending to build the theater. The same also goes for the side speakers - you need good distance between the sides of the couches and the walls for speakers. If not, then again your soundstage shrinks so much that the only person with a great experience will be in the "money" seat (of course, that's the person who paid to build the theater!)

My home theater is 18' by 14' like yours, however I don't have a back wall behind the couches (it's on the 2nd floor and the couches back up to a railing that over looks the 1st floor). I have 15' between the screen and the viewers. The screen size is approx 120" on a 2.35 aspect ratio. It takes a beefy projector to light up a screen that size, so pick your budget and stick to it. You might find that a two or three seater theater in a smaller room works better for you. IMO it's better to have a smaller theater that meets the THX specs rather than a larger theater that really falls short. When all is said and done, my "Theater in the home" project will run $40k in the first three stages, then an additional $10 in additional accoustic treatment for the room.

My $0.02.

I'll stick to the shop.

The first one is going to be way too small- you would discover that the first time you tried to rip an 8' board. ;-)
The second one should be big enough for most anything. With a little planning, you should not need mobile bases. I'd think about double doors to the "various" area- that way when you are working on a big project, you can open up and use that area for assembly w/out navigating a small door.
By the same token, I'd consider making the walkout a double too.
 
Good input all!

Workshop - The walls are all poured concrete, so it's too late to make the walkout door a double door. But I agree, I wish I had now! Double doors on the other end, maybe opening to the left instead (so it'd be a straight through from the outside door)...that's not a bad idea at all.

I do have asperations of making things like desks, bookshelves and an entertainment-kind of center someday, so I probably will end up working with somewhat long boards.

Theater - I haven't priced projectors at all...or really *any* of that, since I know it's a minimum of about 5 years away. Who knows how projectors will have changed by then.

I guess I hadn't really planned on a THX-level area...more of just the "ooo, cool!" big screen effect. I can see going down there to watch football games as much as movies.

A dropdown screen in our *current* movie viewing area would be an interesting challenge. The acoustics aren't the greatest...it's a greatroom open the 2nd floor, with walls only on 3 sides. I put in rear speakers in the area, so I have 5.1, though the speakers are about 11 ft off the floor...that's as low as they can get.

So here's the real question....if a theater of *any* kind is at least 5 years off (as is the bedroom, bathroom, etc)...would it be better to just take up a TON of space down there for the workshop, and when we finally decide we want to start finishing that area, I may end up having to move some walls and rearrange the workshop area? I figure by the end of 5 years, I'll either be seriously dedicated to woodworking or I'll find I"ve hardly ever used the area. And if I'm seriously dedicated, I would probably then find room outside the house for a separate workshop instead of making my area in the basement smaller.

I was just thinking if I could find a sufficient amount of space down there as-is for my workshop, and still room for the theater, then I wouldn't have to move anything down the road (but granted, 5 years down the road, at least.

My theater is my great room as well. I stayed away from drop-down screens like the plague -- I went with a fixed screen. The 3-walls worked great for me, becuase the ceiling behind the couches starts to curve down (very good for acoustics), and it allowed me to mount my rear speakers behind the couches (another huge plus). The major downside of this is you are not accoustically sealed from the rest of the house. I'm into my theater so much I really don't care too much about that. They can join me or put up with the house being really, really loud for an hour or two ;) Keep in mind, concrete walls are awful for acoustics (they reflect everything, allowing nothing to "pass through" and/or absorb. You'll need 3x or more of the amount of accoustical treatment the basement than you would in your great room.

Well, any finished area down there will have insulation and framed walls all the way around, including along the concrete walls....it won't just stay bare concrete.

If I use our current greatroom/TV viewing area for the "theater", then really all I'm gaining is just a bigger screen. I think the idea of excluding it from the rest of the house greatly appeals about a theater...plus it allows for watching movies in full darkness at any time of day. There's no way to make our current greatroom dark during the day, just about an entire wall to the 2nd floor is windows.
 
Ok, so we think we've settled on the area that is the workshop and theater area in the first floorplan as being the current workshop. It loves lots of room for the kids to ride their bikes around, and leaves a small little area outside the wiring room for storage (as well as under the stairs still).

So that gives a workshop area about 40' long and going from 10' to 12' wide. Kinda narrow, but lots of room for long boards.

Next up is deciding whether we're going to insulate and put walls up along the outer concrete wall. I'm not sure how much insulation would matter to the overall comfort of the room...I'm sure I'll have a space heater either way. I'm mainly thinking about having a place to hang stuff, but I could just use tapcon whereever I need to attach 2X4 to the wall.

Does anyone have any experience with building an enclosed area in the basement like this, in regards to if insulating is a good idea? I've been told the 2 main options are to use the blue foam and glue it to the wall, or to use 2X4's and fiberglass insulation, but offset with a 2X6 top rail and bottom rail so there's an air gap.
 
I went with 2x4's and foam, been about 9 months but I did notice a big difference from last winter. Though I did some other things to the basement with the remodel that helped. Along with the milder winter I went through about half as much propane this season.
 
Thanks DL, that's great input! Probably anything I do to cover up some concrete is going to help...though I'll still have the entire floor to deal with.

For the foam, I've heard a couple different ideas of how to do it. Do you basically just glue the foam boards to the wall, and then tape the seams? And then you just build your 2X4 wall right up against it?
 
Well I sealed the walls then my contractor glued up the foam and built the wall in front of that if I recall correctly. I should have some photos at home I can check later.
 
Sorry, late to the thread. I've spent a lot of time thinking about my basement renovations, the past couple years. My basement was already finished when we moved in a few years ago, but it was re-renovated since then (water heater broke, ruined all basement flooring).

In my basement, I have a workshop, guest BR, wiring/mechanical closet, playroom, and hallway, similar to your needs. The kids' playroom will become a 'media room' in 5-6 years - not a dedicated theater, but a room for entertaining, with a fixed screen, and hopefully a small kitchenette (wet bar/fridge/seating, good for drinks and easier for guests/in-laws staying in the guest BR).

A contractor told me that the kitchenette sink drain didn't have to be located in close proximity to the existing bathroom - a pump could take care of it.

I don't have a dedicated woodworking shop, it's a multipurpose room where I can work on any project - electronics, computers, wood (hopefully some metal someday, too). I'll have some basic wood working power tools, and a dust collection system, but it's not (and won't be) a dedicated room. It's MY space, someplace the kids aren't allowed in unless I'm there (dangerous stuff there), where I can do as I please (unlike the rest of the house ;)).

Finish the 'theater area' and the bedroom (and a hallway area), leave the rest of the basement as a relatively unfinished workshop area. After a number of years, you'll know better about how you want the workshop laid out and finished - you may decide on a closet for a compressor and 220V dust collector, you'll know where your 220V cabinet saw should be located, and you may want a permanent dust collection system (or you may not want any of this ;)).

Dedicated home theaters are awesome, if they're convenient and used often. I think my media room would be used more if it was good for 'hanging out' in, as well as for movies/TV/video games. Each approach has a subforum at AVS - Dedicated HT Design & Construction and General HT and Media/Game Room subforums. I've spent a lot of time in both subforums, and the multipurpose room is better for my needs. I'm sure you've checked out the HT subforum - tons of good info on renovating basements there.

Lots of people post their basement diagrams in those subforums - might be worth it for more ideas (if you like to overthink things).

Real important point here is vapor barrier. Paint your concrete walls with products designed for that purpose. I don't know all of the details but you don't want mildew growing in your walls so ask someone whow knows all about that first.

If your basement is below grade insulation is important but not super important, I would look at furring strips with foam panels. If it is above grade and you get real cold in the winter, I would put up 2x4's and fill the space with fiberglass batts.

Who says you can't put a double door to the workshop? Poured cement cuts just fine with a gas powered saw with a masonry blade. Just header it off. You will love having double doors.
 
What kind of compressor do you guys have? My large oilless Husky died last fall, and I need to pick a new unit, but can't figure out what to go with.
