Thread: demolish bungalow but leave floor?

It would depend on what the fooring timber is (how durable the timber specie.) A photo would help to identify if you are unsure.
No matter what the floor is made of, one major factor would be the need for expansion and contraction once the floor is exposed. This is why a deck is put down with a gap between each board, also to drain water off the floor. Assuming your floor is tongue and groove you will have issues on both counts.
Hope this helps.

Yep, I knew I'd get value out of this forum. Yep, it'll be tongue and groove and it sounds pretty straightforward...the floor will expand, contract, warp and crack over time. I'll remove it as well. Thanks rustynail.

Rusty is right in that it depends on what timber the floor is made from.

My family home was over 100yo with a verandah running all the way around, made of old T&G Tassie Oak floorboards. They were rough 'n splintery on the surface but fairly substantial and far from needing replacement.

In the 50 odd years I know of the place, they were never oiled.

So, it is a possibility that it'd work for you... but personally I think I'd replace them now, while they're easily accessible, just to be sure the job doesn't need redoing 5 years from now, y'know?

You could pull up the old floor, rip the tongues and grooves off the boards, and reuse them for your new pergola floor, might even be better than new timber.

Thanks for your comments. Not far away from the demolition job now. I'm not sure what timber the flooring is. After removing the boards I would take a sample to the local hardware/timber joint? What would be the best way to 'rip the tongues and grooves off the boards' if I went that way?

The best way will depend on what tools/machines you have available.
A table saw or plane will do a nice job.

Bung em through a thicknesser, a hand full at a time. Check grain direction for each piece to get a good finish.
