Belgravia Unfinished Oak is a premium solid oak herringbone floor supplied as a blank canvas, giving you complete freedom to create a truly bespoke finish. Crafted from full 18mm solid oak, each generous 90mm parquet block showcases the natural beauty, character and grain variation of genuine hardwood, ready to be finished exactly how you want it.

Unlike pre-finished flooring, Belgravia allows you to choose your own stain colour, sheen level and protective finish after installation. Whether you're looking for a light Scandinavian-inspired tone, a rich smoked oak appearance or a traditional deep wood finish, the final result is entirely in your hands. This flexibility makes unfinished oak a favourite choice for interior designers, architects and homeowners seeking a unique floor tailored to their space.

The larger 90mm block size gives the classic herringbone pattern a more contemporary feel while retaining all the elegance and character that have made parquet flooring a timeless choice for centuries.

Once installed, the floor can be sanded and finished on site, creating a seamless appearance with no visible micro-bevels between boards. As a solid oak floor throughout its full thickness, Belgravia can also be sanded and refinished multiple times over its lifetime, ensuring it remains beautiful for generations to come.

Why Choose Unfinished Oak?

  • Complete Design Freedom – Choose your own stain colour and finish to perfectly match your interior.
  • Create a Truly Bespoke Floor – No restrictions from factory-applied finishes.
  • Seamless On-Site Finish – Sanded and finished after installation for a beautifully uniform appearance.
  • Future Flexibility – Change the colour or finish in years to come without replacing the floor.
  • Natural Character – Showcases the authentic grain, knots and beauty of genuine oak.
  • Long-Term Investment – Full 18mm solid oak can be sanded and refinished multiple times.
  • Perfect for Renovation Projects – Ideal for period homes, luxury renovations and high-end interior design schemes.
