If you are looking for a simplistic solution, take a look at these PREFINISHED Oak 4L Roomfold deluxe doors. These doors and frame come ready for immediate installation with no decorating to do on site. This roomfold set can be trimmed by 50mm in height ( proportionate to the rail depths ), and by 50mm for a 3 door system (10mm off each side of the frame and 10mm off each door ), and a further 10mm per door for sets with more doors. The set comes complete with flat pack frame, head & base track, running gear, hinges, drop bolts and glazed doors, with clear toughened glass.
The only thing you need to add is handle and latch to match your existing furniture. Fully reversible, so you can decide which room your doors open into, and which side the doors fold to, this fully universal interior bifold door is an ideal choice.
