Tiles can be super expensive and alternative floorings such as Lino can look naff. If you insist on that geometric flooring, but can't afford the £500 minimum excess for tiles, give painting a go. All you need is some masking tape and durable floor paint and away you go. If you're going for the monochrome look, start with the palest colour first and then gradually go darker as you go on. Painting the darkest colour last will give you those super straight clean lines.
If mid century modern is more your thing, why not give these tri-coloured geo's a go. They certainly make the statement and will give you something completely unique.
