Incase anyone is thinking about starting an architecture practice; my accountants just informed me I earned £21k in 2019/20. For context I started what is sometimes regarded as a reasonably successful practice 6 years ago and I’m 39 years old.

In the course of our own research, sometimes we come across planning decisions that are so far outside the constraints we work to ourselves that it completely blows our minds. These 8.3m (eight point three) deep extensions were approved by @lb_southwark in 2013...

There’s a significant problem in this country that if one person misbehaves on or near a bench, this outweighs the countless times said bench has provided comfort, rest, a place for conversation. It’s a miserable way to manage our public spaces.

Working as an architect in both private and public sector gives you a keen sense of where the money is and 40 years of neo-liberalism has had its effect. It’s crazy that we work with budgets for transformative public projects that we’d turn down if it was a kitchen extension.

The project shows issues typical of a ‘traditional’ approach: compromised internal spaces, poor accessibility and details/materials that can’t emulate the buildings they are referencing. When you unpick these projects you start to see that they can’t be judged purely on ‘beauty’

The new terrace keeps roof/ floors at same level and steps main entrances. Traditional terraces step from house to house following the natural gradient of the road. It creates some pretty weird internal conditions with sash windows finishing close to the internal floor level.
