Is it an ultra-cool dolls' house or is it a coffee table? Well, actually it's both. A dolls house is one of those bulky, often expensive, toys that take up floor space and have limited play life.  Amy Whitworth designed the QUBIS Haus to have a dual purpose as a coffee table and a dolls house. The ingenuity of the concept combined with the sophisticated architectural quality of the design is what makes it a brilliantly big idea for a tiny space.

With its slots for removable walls and various additional room sets, budding architects can spend hours putting together their individual schemes and then helping the little dolls move in to their new house. 

Magnetic oak blocks click together to make the furniture. Once play time is over, the mini furniture pieces can be removed and the unit is ready to be used as a standard coffee table again. It looks so lovely fully furnished, however, that many people choose to use it as a coffee table whilst the dolls get on with their lives underneath!

If you believe you have spotted a piece of furniture or equipment that is a brilliantly big idea for a tiny space, do tell us about it.

Every week on Don't Cramp Our Style we will be highlighting brilliantly big design ideas for tiny spaces and starting out in pole position is Made.com with it's Lovebird sofa. 

Designer Je-Uk Kim won a competition run by the Design Museum and Made.com to design an innovative and compact two-seater sofa. The Lovebird sofa, inspired by the colour of lovebirds, is the result. 

It's easy to see why it won. Underneath the sofa there's a pull-out coffee table, the inside of which is hollowed out for storage, and a poufe. And, if you put the poufe at the end of the sofa it transforms into a single bed. 

It's the must have piece of furniture for a studio apartment or bedsit and perfect for tiny living rooms too. I reckon you can stretch it to fit more than two bums when you've a crowd around; and there's that extra space on the poufe too. 

It's not cheap at £1,999, but having been displayed as part of the Design Museum's Future is Here exhibition it's well on its way to becoming a design icon and should at least hold its value. I'd go for the orange colourway. 

Do you know of another brilliantly big idea for a tiny space? Perhaps one that can even tip Made.com off the top spot? Do tell
