Many older homes in the UK have hidden wooden flooring, often
covered by carpet or lino. If you're lucky enough to have such a
treasure in your home, renovating your wooden floor can bring new life
to your space as well as increase the value and saleability of your
property.
According to the National Wood Flooring Association (NWFA) in the US, Estate agents reported that new wood flooring yields the largest financial return upon resale.
According to CNN, wooden flooring can add as much as 3% to 5% to the value of a home and, in the UK, the Express also reports that wooden floors are favoured for adding value.
Well, obviously there's a potential upside in the value of your property, as noted above. But if you're asking is it worth restoring original floorboards and restoring pine flooring, that also depends upon your own taste in decor and the benefits of not having to put expensive carpet down, that then needs constant hoovering and attention over time and will also have to be replaced in the future.

A beautiful wooden floor can add real value to a house...
Bringing an old wooden floor back to prime condition by floor sanding and refinishing, such as parquet flooring refinishing will save reinstalling a wooden floor and can make your wooden floor a real asset to your house again. Imagine therefore finding a hardwood floor, that you have an original parquet floor or floorboards under that old carpet or lino. Revealing wooden flooring, particularly an oak floor - where oak floor restoration is particularly rewarding - or floorboards can suddenly create an asset for your property, where before there was an old floor covering which did quite the opposite! And yes, floorboard restoration is a thing, too!
For this reason, stair sanding, and refinishing stairs can provide that natural wow factor for your house, right as people come in. First impressions count!
According to the 'National Association of REALTORS® Research Group' '2019 Remodelling Impact Report', new wood flooring and refinished wood flooring were 4th and 6th respectively in the 'rank of projects’ appeal to buyers' when refurbishing a house.
In summary, wooden floors offer a variety of additional benefits beyond just their aesthetic appeal, such as environmental friendliness, allergen-free living, noise reduction, improved indoor air quality, timeless appeal, and flexibility.
Parquet flooring can also add value, due to the design and timeless appeal.
"Parquet flooring is a decorative type of flooring that can add value to a home due to its unique design and elegance." (Houzz, "Parquet Flooring: A Guide")
