Thread: Done. My DIY loungeroom. Never again.

All finished - right down to the little white caps that hide the screw heads inside the carcasses. First time ever I think I've finished a DIY project completely.
I got some good advice here over the last 6 months. Thanks for that.
It's a 5m x 5m room.
Down one side is a set of drawers, a built-in gas fireplace, and a cabinet that hides the TV. The drawer fronts and cubboard doors are in gloss poly. The top of the unit is gloss laminate - I went with that finish rather than get it painted because it should wear better.
Above the heater is a vent I made up from laminated 20mm wide strips with 20mm spaces - I didn't want an aluminium grill or anything like that. The heater sits on a 60mm slate hearth that I got a local stone guy to make for me.
The black strip along the front and down the right hand side of the bench is 100 x 60mm steel painted black. The splayed hearth surround is also 6mm plate steel. I made them up out in the backyard and painted them with BBQ paint and a little foam roller.
Under the window, are two book shelves from 32mm veneered board. They were a killer - long and heavy.
Instead of timber uprights, I made up 6mm black steel pieces that I set back and rebated top and bottom. They are not really visible, which is what I wanted i.e. it reads as two long shelves with no supports.
The other side of the room is cupboards with the killer end curve.
The floor is cypress pine, I stripped the old gloss poly and stained it very dark and used a finish called OSMO - hard wax oil. (It took me 9 hours to sand the floor with my Rotex 150. What an amazing thing they are.)
In the past when I've done DIY stuff, I reckon the end result has been about 70% as good as what a professional would achieve. This time I'm close to 100%. I think I've peaked. Of course, it took ages.
