Let’s talk money 💰
This is a 19m long loft conversion — and as you’d expect, the bigger the loft, the bigger the cost. But when it comes to lofts, the structure is where the real decisions (and savings) are made.
On this project, we had several options. We were lucky to have excellent head height, which opened up more structural possibilities.
I’m a big fan of the Telebeam system — it’s a great product. But it’s important to remember that Telebeam is just the structural system. The cost mainly covers the aluminium beams delivered to site. You still need to factor in flooring, insulation, timber, and labour to install the structural floor and ashlar walls.
For this project, I worked with an engineer I’ve collaborated with on several jobs. I gave him a simple brief: we were happy to use steels and wanted to design a solution that allowed us to work above the existing ceiling with minimal disruption. That’s exactly what he delivered.
Once the steels were installed, we could run the joists in the opposite direction and sit them directly on top — simple and efficient.
This highlights an important point: working closely with your engineer can produce a design that works not just structurally, but practically from a construction perspective too.
Now let’s look at the numbers:
• Telebeam system quote: £36,000• Installation, materials, flooring & ashlar walls: ~£10,000👉 Total: ~£46,000
Our alternative design:
• Steels and crane: £6,000• Materials insulation and labour for floor & ashlar walls install: £11,000 – £13,000👉 Total: ~£17,000 – £19,000
That’s a saving of roughly £27,000.
That saving alone covers the remaining structure ready for plastering. (We are not doing mechanicals or finishing just purely structure)
I really like Telebeam, and it absolutely has its place. But on certain projects, the cost just doesn’t stack up. Good design and collaboration can make a huge difference financially.
