One of the worst feelings in the world is to leave home for a week of relaxation…and an hour later, wonder whether you left the oven on. Scenarios like this can cause unneeded stress and, in the worst case, significant property damage. The Off Door Handle could help prevent both.

The door handle, created by designers Eun Ah Kim, Jinhyuk Rho, and Maria Rho, was a 2011 Red Dot Design award winner. The door handle is connected to the home’s main power and gas supplies, allowing residents to turn both off and on easily.

A small dial at the end of the handle lets users choose whether to turn off the electricity, gas, or both upon leaving. After making a selection, the user presses the button on the end of the handle and then simply turns the handle as usual. The selected services are then turned off.

Upon residents’ return to the home, the door handle re-activates the services that were previously turned off. According to the designers, this inventive door handle can help prevent home fires and wasted utilities. But if you are away from home for a long period of time, it would be a good idea to have your home security system powered on a separate system.

Opening a door is usually done in a single motion – we take for granted that this is just not possible when it comes to one with a locking mechanism, whether it be low-tech like a key or high-tech like an iris scanner.

Most fingerprint-reading door locks require that you depress an area, listen for a click or maybe look for a light, then grab the handle and go – not a big deal, but definitely one more step than necessary.

Donguk Seo proposes a simpler model that works with a single motion – just grab, press and push or pull all in the same simple motion, while an LED on the end lets you know if there is any issue with your first try.

Well-suited for truly open loft living, this bathing system is not for the shy – it combines the openness of a hot tub with the jets of a Jacuzzi and the functionality of a shower, all in a sleek UFO-shaped package.

The downside is that there are in fact no sides – one has to wonder a little whether the shower portion will work well without a curtain, even with the large footprint of the round tub below.

Spiritual Mode makes this odd marvel with dual steel side faucets and a series of semi-circular bubblers around the base, distributed evenly for easy multiple-person use. The whole thing looks prepped to take flight, once the docking clamps (faucets) are folded back from the sides.

One has to wonder what is holding back this kind of innovation – is it health or simply convention? The idea is simple: combine the two water-using items found in any men’s bathroom.

Yeongwoo Kim designed it with the utmost aesthetic simplicity, and it speaks for itself: the water clearly recycles to add in flushing the toilet – semi-opaque frosted glass hides the first sequence’s function from view as one leans forward to wash hands.

The result is a graywater reuse system that requires fewer pipes but also saves space, as the same vertical area can be used both for urinating and hand washing, presuming, of course, that the hygiene of such proximity does not prove to be a problem.

Not every home can have a backyard or deck for grilling, so for those that lack good outdoor space this compact cooker could be the perfect way to entertain guests.

From Gunni, a European manufacturer that knows small spaces, this unit acts like a regular kitchen island on wheels when not in active use, but slides open to reveal additional functionality on demand.

On one side sits a drawer for knives and spices, while the other features a platform for grilling up steaks, sausages, vegetables and more. Shelf storage below also serves to stabilize the elegant wood-and-steel structure.
