Our Verdict: A challenging, creative and vividly wonderful theatre experience. 4 stars.

It’s incredible how quickly you and your merry band of strangers lose the awkwardness of not knowing each other... And yet, just as quickly, the adventure ends. The timer that was set at the beginning erupts like an alarm clock interrupting your dreams... It turns out twenty minutes is just enough time to excite you, inspire you, and leave you gasping for more.

[Kriebel’s] words are powerful, conjuring rooms without you even leaving your seat. The timer went and our cries of disappointment were spontaneous and real... This game is absorbing, enlightening and often funny.

As a piece of spoken word theatre, Kriebel’s delivery is tone perfect with soothing descriptiveness... It is the journey and time spent in a friendly circle of fellow adventurers that is the essence of this beautifully realised work. 4 stars.

The Unbuilt Room is a powerful reminder of how beguiling simplicity can be… It was also however surprisingly funny, helped by Kriebel’s ability to play the almost computerised games master, and his very impressive grasp on the structure of the game.

This experience is all about discovery – discovery of an environment, and discovery of its rules… It’s a powerful reflection of the frustrations of life, and a fascinating revival of a unique style of storytelling.

An inspired experiment in teamwork.

Despite its simplicity this is a deeply well thought out and complex work of theatrical art. This is in stark contrast with the kind of theatre that so often appears complex in order to hide its lack of true originality and depth…
The Unbuilt Room is not only clever, but it is fun… There are but a few theatrical productions that can combine humour and entertainment with the profound, this is one of them.

At the end, you’re left wondering what’s through an unopened door you only ever imagined in the first place.
