So buildings then are just objects in space which can only be accessed through one door and experienced in one dimension? What a ridiculous notion. I'd rather (and do) subscribe to the notion that buildings have a responsibility to engage and respond their surroundings on all sides. The south side of Boutique's loft building, Corus' north facade, and the disastrous Mystic Pointe area are all the results of architects and planners focusing on a building having one or two 'show' sides while allowing the rest languish in spandrel panels and large expanses of precast.
Why would you, or should you, not expect to see doorways on the sides of buildings, or retail emporiums and restaurants on side streets where you'd least expect them. Pearl St. for instance, could be a fantastic little pedestrian zone, but because it has been relegated to a service road, no life is allowed to flourish there. Likewise, I'd much rather travel down Hohlenbergs Kvarter than Ekvipagemestervej since the mix of uses, and the vibrancy of the neighborhood would surely comfort me more than the ass-end of an Opera House. But hey, we're all different, right?
