Please see a few images of the previous Monks benches I have created.
These are all created using good quality pallet timber/sheet timber.
Lids are normally affixed to the frame using brass coloured piano hinges.
The dimensions for these are normally:
45cm High (Seating/Storage part)
45cm Deep (Seating/Storage part)
100cm High (For the rear part).
These pieces are all finished in your choice of colour.
