As a general rule, building a new building is easier than trying to do surgery on an existing one, because you never know exactly what you're going to find when you start the latter. But there are instances where surgery is necessary.

According to Bloomberg, developers in London are becoming increasingly interested in the airspace above existing buildings, and it supposedly started because of some policy changes:

In 2020, then housing minister Robert Jenrick introduced reforms that relaxed rules to add airspace builds above existing buildings. Owners can now construct additional residential stories to either expand their own dwelling or to create new units altogether without going through full planning permissions, which are often a long and costly process. This was part of a broader set of reforms to boost housing supply, and the current Labour government has not shelved these changes.

Here's an example site listed for £150,000:

The site currently comprises the roof and airspace above a 3-storey mixed-use residential-led block (Block B) within The Glassworks Development.

The existing development was constructed in 2017 and comprises 23 residential apartments plus ground floor commercial space, all of which are sold off on long leases.

I had an old boss who was very interested in this idea. For him, it was "free" land and a way to further extract value from an existing real estate portfolio. Of course, it's also a way to build new homes in already built-up cities. Some industry people think that London could accommodate up to 180,000 new homes using this strategy.

But these are not simple builds. Can the existing structure and foundations support additional levels? How do you modify the existing elevator(s) while the building below remains occupied? How do you do the mechanical tie-ins without impacting the suite(s) below?

All of this makes me wonder how feasible it will be for London to build 180,000 new homes in this way. If it can, that would be a great accomplishment, and one that other cities should aim to emulate. But regardless, I'd love to get under the hood of one of these projects.

We arrived in Revelstoke, BC, yesterday afternoon. The last time I was here was in 2015, and already I can tell that a lot has changed since then. I'm sure I'll have more to say on this over the next few days, but one of the first things that stood out to me was the city's signage.

In 2020, Revelstoke City Council approved a $3.2 million, multi-phase wayfinding plan designed by Cygnus Design Group. So, what I have been seeing are the first completed phases.

Wayfinding signage serves (at least) two critical functions. The first, and most obvious one, is that it tells people where they are and how to get to where they likely want to go. The sign in the cover photo of this post is what you see right before you enter downtown.

The second function of wayfinding signage is to send other signals. It communicates to visitors that things are well-managed, that the place is hospitable, and, most importantly, that the place attracts visitors from around the world. It conveys importance.

Before I had even reached downtown, the signage made me think to myself, "Wow, Revelstoke has grown a lot since I last visited!" That's the power of good communication, and it's a vital part of placemaking.
