Interieur 2014: Belgian furniture brand Bulo has launched a range of modular office furniture based around black ash wood frames.

Developed by the brand's in-house designers, the Dan collection includes black-stained wooden beam and ladder elements that can be combined to build a range of furniture pieces.

Anodised metal connectors are used to construct the frames into coffee tables, desks, shelving units, storage rails and a ping-pong table.

These are completed by surfaces in a variety of colours and finishes that can be reconfigured when necessary.

"Thanks to its design, you will be able to change your standard Dan desk into a standing desk just by lifting the table top a level higher," said a statement from Bulo.

Dan, named after a ranking system in Japanese martial arts, includes nine height and width options for the ladders to be configured with six beam lengths.

The horizontal ash elements feature a diamond-shaped section, while the vertical supports are cylindrical with a flattened face where they meet the perpendicular braces.

T- and X-shaped connectors slot onto the frames to assemble the pieces, which are designed and manufactured by Bulo in the Belgian city of Mechelen.

Small wooden sections can be used to attach beams to the wall to create rails, or the ladders can simply be propped up and used to hang garments.

Bulo launched the Dan collection at this year's Biennale Interieur event, which took place in Kortrijk last month.
