Out of curiosity I compared the price of a tall oven cabinet to the cost of materials for one I just made. Cliq's price was $1325 delivered. My cost for materials was about $150 using 3/4" birch plywood for the sides and bottom of the oven opening, 1/2" plywood for the drawers, shelves, top & bottom and 1/4" plywood for the back. Drawer slides are Blum undermount soft close, door hinges are Blum compact soft close and handles are stainless bar. But quotes I got at HD put that oven cabinet at almost $2000 and that cabinet had a lot of cost cuts in materials.
FWIW, I kept material costs to a minimum (fixed income and all that) and will be painting the sides to create a weathered look. So high quality hardwoods and plywood was not needed, like in our last house. But the cost savings was substantial enough to compel me to make the cabinets even though I'm slowing down a bit with age.
