Walk into any toy shop today and you’ll hear a familiar reaction from parents and grandparents: “LEGO never used to cost this much.”

And they’re right. LEGO is noticeably more expensive in the UK today than it was when I was growing up in the 1960s — not just in absolute terms, but relative to average incomes. Yet despite the rising price tag, the iconic 2×4 brick hasn’t shrunk. The system is the same; the world around it has changed.

Interestingly, the same could be said for housebuilding in Scotland — especially here in the North East of Scotland. Homes aren’t literally smaller than they were in the 1960s, but they often feel that way, and they certainly cost far more to build. Rising material prices, labour shortages, and higher energy‑efficiency standards have pushed construction costs to record levels.

Yet when it comes to public subsidy to increase the supply of affordable homes, is the review of grant benchmark for affordable housing keeping pace with the perma-crisis in the local and international economy? The Scottish Government’s statistics released in December 2025 would suggest not.

The AHSP out-turn report for 2023-24 would suggest that the requirement for above benchmark grant is becoming the norm rather than the exception, with 62% of City & Urban approvals being over current benchmark grants.

So, here’s the twist: LEGO may actually hold the key to building more affordable, sustainable, and higher‑quality homes.

LEGO sets today are:

• Larger
• More detailed
• Packed with specialised micro‑elements
• Often tied to expensive licences (Star Wars, Marvel, Disney)

Add the UK’s 20% VAT and fluctuating import costs, and the result is clear: LEGO is more expensive than ever, especially medium and large sets.

Yet the price‑per‑piece has stayed broadly similar. What’s changed is the complexity.

Scotland’s Construction Cost Problem

Construction costs in Scotland have risen sharply since 2020, driven by:

• Rural logistics
• Labour shortages in the Highlands & North East
• Post‑COVID supply chain volatility (the latest being the supply and cost of copper for electrical and plumbing)
• Higher energy‑efficiency standards (airtightness, triple glazing, renewables, EV connections)
• Increasing safety and accessibility standards (fire suppression systems for all house types) 

By 2026, bespoke Scottish builds sit at £1,750–£2,750 per m², with Aberdeen and Aberdeenshire typically 5–15% higher due to transport distances, contractor scarcity, and challenging ground conditions.

A typical 3‑bed home (90–120 m²) now costs:

• £157,500–£247,500 (Scotland average)
• £180,000–£288,000 (Aberdeen & Aberdeenshire)

And that’s before land, fees, utilities, landscaping, or contingency.

Just like LEGO, the system hasn’t shrunk — the complexity and expectations have grown.

People often claim LEGO bricks are smaller today. They’re not. The same perception applies to homes. Modern houses feel smaller not because the industry shrank the “standard brick,” but because land is more expensive, energy standards require thicker walls, designs favour efficiency over excess and construction costs push developers toward compact footprints.

The lesson? Perception of shrinkage often reflects rising costs and rising complexity, not actual reduction in core components.

What LEGO Can Teach Us About Building Better Homes

This is where the comparison becomes powerful. LEGO’s design philosophy offers a blueprint for more affordable, flexible, and sustainable construction — especially in regions like the North East of Scotland.

LEGO bricks fit together perfectly across decades because the system is ruthlessly standardised, they can be reused endlessly and the tolerances are famously tight — around 10 micrometres.

LEGO’s simple connection system is ideal for automation — and researchers are already applying this to real buildings. In addition, LEGO sets break complex builds into manageable sub‑assemblies, and its system is built for compatibility and long‑term use.

LEGO’s rising costs and expanding complexity mirror the pressures facing modern housebuilding. But LEGO also offers a powerful lesson: a well‑designed system can remain compatible, flexible, and high‑quality for generations — even as the world changes around it.

As much as housing associations are committed to building more affordable homes to meet the challenge of decades of underinvestment in new homes – there will never be enough public subsidy in the face of rising costs.

However, if Scotland, and particularly the North East, has the ambition and  can gain the capacity to innovate construction by truly embracing modularity, precision, reusability, and system thinking, we can build more homes that are:

• More affordable
• More sustainable
• Faster to construct
• Easier to maintain
• And better suited to the needs of future generations

Just like LEGO, the building blocks don’t need to shrink — we just need to use them more intelligently.
