Modern Glass Extension in Maida Vale: Solving a Structural Mystery

Sometimes even the most straightforward of jobs can leave the team a little stumped. But this beautiful home in Elgin Avenue, Maida Vale, with its elusive steelwork and glassy ambitions, was no match for Matt Barry ARB, full-time architect / part-time detective.

The project vision

When we were appointed to take over the technical design and build of this rear glass terrace extension in Maida Vale with a living wall, the vision was simple: a light-filled glazed addition that connected seamlessly with the existing home, elegant, modern and green in every sense.

A sleek glass terrace, softened by a lush living wall, forming a tranquil retreat from city life. Seems reasonably uncomplicated? Well, that was what everyone thought. Everyone was wrong.

The first hurdle: where was the steel?

The initial step was to work with the engineers to calculate the load-bearing capacity of the existing structure to accommodate the large glass panels that would form the new extension. But as it turned out, the existing structure was something of an enigma.

The home, built in the mid-2000s, came with no historic drawings, no build records, and an owner who had not been involved in its original construction. While Matt made several calls and some subsequent telephone tennis, in search of the original architect through the planning archives, there was no success.

So, with no clear information to hand, the team began carefully opening up the structure to see what lay behind the plasterboard.

First hole: nothing.
Second hole: still nothing.
Hole three and four: same story.

That elusive steel remained, well, elusive.

The engineers warned that without locating the existing structure, the glazed extension could not rely on it. New supporting steels might be required, a change that risked the clean design and ultimate vision of the project.

The search for the missing steel deepens

For an architect, the idea of a compromised vision is an unbearable one. So rather than accept defeat, Matt decided to dig deeper, coordinating closely with the build team as they carefully investigated one area after another.

The breakthrough came when the team fully exposed one of the known steels. The steel itself met expectations, but it also revealed a crucial clue: the original contractor’s name stamped on the beam. Suddenly, the project felt like an architectural whodunnit.

Armed with this lead, Matt began making calls. Tracing the trail from the contractor to the original site manager, and then onward to the first structural engineer. Each conversation felt like another step in solving the mystery.

Their firm still had a small image of the project mid-build on their website and with conversation leading to another, Matt uncovered a forgotten archive of hand-drawn plans from the early 2000s.

After some careful digging and a fair amount of suspense, the elusive details finally surfaced. The structure was decoded, the mystery solved, and the project could move forward, the original vision intact.

The moral of the story

We always talk about how you never quite know what you will find when you peel back the plasterboard. But with the right people on your team; the ones who will pick up the phone and follow every clue, anything is possible. They refuse to give up on the design until it is complete.

This Maida Vale mystery may have started as a simple rear terrace extension with a living wall. But, it ended as a reminder that architecture is not just about buildings, it is about curiosity. It’s about collaboration… and a healthy dose of detective work.
