Classic Pine Country Armoire

Design and construct the armoire base and top sections as separate 1-piece units. Then consider using unglued, loose mortise/tenon, slotted, screwed or dowelled joints to connect the armoire sides and back together to fit snugly within the base and top. Same goes for attaching to the bottom and top pieces. Add extra bracing and/or knock-down furniture hardware inside to reinforce the rear and side panel joints, and to where the top and bottom sections join to the sides and rear. Then just add armoire doors with screwed-on hinges.

With the above design, you would take apart the armoire in this order (and reverse to assemble):
- remove doors
- remove top
- loosen/remove knock-down furniture hardware or bracing from the armoire's rear and side panels, and from the top and bottom sections
- pull apart/remove sides and rear panels from base

Basically, design your armoire as Ikea does, but do yours better with the hardware hidden (from exterior view) and with solid wood and good finishing!

Good luck finding some plans. Looking forward to your armoire photos when done.

Many here would know how to approach building such a unit
using knock-down hardware, but you really need to do
some research yourself since there are many systems for
doing it and they suit different styles of work. Most of the
IKEA type hardware is designed for particleboard and
the drilling for such hardware is tricky to get right in
a home shop. Not that you can't do it.

Another style of RTA (ready to assemble) hardware is

I think it is more forgiving in a small shop with basic equipment
and also generally concealed.
