Thinking about doing floor-ceiling bookcases in my study. Ceiling is 9' in
In another room I'm doing base cabinets with the bookcase on top of them -
to overcome limitations of a 8' sheet of hardwood plywood.
Just wondering - if I want to skip the base cabinet approach - and make a 9'
tall bookcase, what are some of the techniques involved? How do you folks
get 9' of sides out of a 8' hunk o' plywood?
I've considering asking the same dude that auctioned off the Time Machine to
see if he has a plywood stretching machine. Or warping the space time
continuum. In the meantime, I thought I'd ask the wreck.
Look for some place that sells 9' plywood. It's available, usually fairly
easily found if you check local lumber dealers, plywood dealers, but don't
expect to find any at HD or Lowe's.
Failing that, build it 8' tall in 2 sections, with a 1' tall center section
with, maybe, a drawer or 2 in it. Might also be a bottom section.

You can sometimes find 4x10 ply at local outlets. Noticed some at the
orange borg once. Then make them in two sections as Charlie says. This
has the added benefit that you can get close to nine actual feet (you
slide the top part in place, rather than standing the whole thing).
Think about how you will install and trim the boxes. You can probably make
up most of the 1" with the way you construct:
1) You are going to have to be short of 9" just to stand the cases up.
2) If you put your bottom shelf up about 6" - 8" off of the floor, this will
allow you to set the "boxes" on a 2x platform and trim up to from the floor
to a location on the front of the hardwood box. This trim might consist of
several pieces that suggest base trim and some detail. This will give the
illusion the bookcases extend all the way from the floor.
3) Likewise you can leave space between the top of the box and ceiling to
fill and trim with appropriate mouldings. This will also keep you from
dinging up the ceiling when you set them up. As a previous post suggested,
you cannot expect the ceiling to be flat. Your top layer of moulding will
have to be a little flexible to make for up some of the waves you don't
Something more important to thing about first, If you build the 9' bookcase
as one unit to fit in a 9' tall room, how are you going to stand it up in
the room? You will have to get through a door way which means leaning the
cabinet over. Now consider that to stand a 9' cabinet up, you need more
than 9' of clearance. From front bottom corner to back top corner is more
than 9' on a 9' tall cabinet.
If your cabinet is only 12" deep at the widest part, a 9' cabinet needs 9'
11/16" of clearance to stand up.
Now for your question of how to stretch 8' to 9', cut the 8' long plywood
panel and frame each piece it. let the framing make up the difference.
Framing 2 side panels with 3 pieces of 1x4 stock will give you about 10.5"
more length overall.

You can set your eight foot bookcase on a six inch plinth and apply a
six inch cornice to the top.

I've got a lot of books that I only get to once in a great while (like
when I move). A 9' shelf would be great.
Personally I'd build it with a 6" base and close the top with 6"
crown. You are going to need to have a bit of working room height-wise
anyway because it is very difficult to get a 9' piece stood up in a 9'
fabricated and installed floor to ceiling (9') wall to wall cherry
bookcases in a den this spring. built a 2x6 base to set each 8' unit
on. wrapped it in a cherry base we made. installed a valance backer
at ceiling. covered it in a cherry valance and added crown. looked
awesome. have pics. will try posting later.
building 9' units is risky. in 10+ years of
construction/remodeling/carpentry i have never seen a perfect ceiling
or floor. plus, you can't stand a 9' cabinet up in a room with 9'
'fraid I don't know about sides - when I had to do the same thing for a
10' ceiling I used solid pine sides and just ply for the back (which I used
two 5' sheets that met behind a fixed shelf in the middle.
As for the walls/ceiling not being square - no biggie - just screw it to
the wall and it won't fall over.
And you actually *can* get a 10' bookcase to stand up in a 10' room - IF
you have cornices in the room. I cut the cornice profile into the back
edge of the side, and it went up without a drama.
And those pesky books getting to the top shelf - build a ladder. Nice one
with wheels on it so you can slide it back and forth (although that's kinda
pointless for a single bookcase - I had a total of just over 3.6 metres in
width by 10' high along a wall).
Hope something in here helps.
