This was job for a previous customer of ours in Hemingford Grey, Cambridgeshire.
We had fitted a carpet in this bedroom about a year ago but the customer decided they wanted solid oak wood flooring in the room instead of carpet.
Instead of throwing the carpet and underlay away, we adapted it to fit a smaller room upstairs with a couple of joins in it which was going to be hidden by a bed anyway.
The room which was to have the 18mm solid oak wooden flooring installed had a wooden subfloor so we installed the wood using a secret nail system.
It was finished off with a solid oak scotia around the perimeter to cover the expansion gap.
