Container house vs brick-built house
Building your home in 2026: the choice of material is not trivial. Shipping container vs brick-built, beyond marketing, we look at real figures — price per m², construction time, thermal performance, lifespan, resale value.
Numerical comparison
| Criterion | Shipping container house | Classic Brick-built House |
|---|---|---|
| Delivered price per m² | £1,575 – £2,100 | £1,890 – £2,625 |
| Construction site duration | 3-6 months | 9-14 months |
| Typical surface area for a T3 | 70-90 m² (3-4 modules) | 85-120 m² |
| T3 turnkey budget | £99,750 – £189,000 | £152,250 – £252,000 |
| 50+ year lifespan | Good (paint maintenance required) | Excellent |
| Building Regulations Part L compliant | Yes (external insulation required) | Yes (standard) |
| Building permit | Yes (identical) | Yes |
| Future modularity | Excellent (easy to extend) | Average |
| Demountable | Yes (depending on foundations) | No |
| Resale Value | -5 to -15 % vs brick-built | Reference |
| Bank Financing | Sometimes more complex | Standard |
| Aesthetic | Industrial / modern | Classic, all styles |
Container if you are looking for…
- A quick construction site project (move-in within 4-6 months)
- An optimised budget (-15 to -25 % compared to brick-and-mortar)
- A modern / industrial aesthetic that is embraced
- An adaptable structure (easy addition of future modules)
- A secondary project (seasonal residence, Airbnb studio, luxury cabin)
- Potential mobility (demolish and relocate later)
Brick-and-mortar if you are looking for…
- Long-term family main residence (30+ years)
- Maximum resale value (resale within 10+ years)
- Classic aesthetic, varied styles (traditional, contemporary, regional)
- Bank financing without surprises (bankers are familiar with it)
- Thermal performance Building Regulations Part L without complex engineering
- Maximum acoustic insulation (concrete is more soundproof than steel)
Frequently Asked Questions
Is a shipping container house cheaper than a brick-built house?+
Yes, it's 15 to 25% cheaper at equivalent surface area and equipment. Median price for a container home in 2026: £1,575 – £2,100/m² turnkey (excluding land). Brick-built house: £1,890 – £2,625/m². The savings mainly come from construction time reduction (3-5 months vs 9-14 months) and the prefabricated steel structure. For surface areas above 150 m², the difference tends to narrow as transformation costs increase.
What is the duration of construction in each case?+
Shipping container house: 3 to 6 months total (site preparation + foundations + installation + conversion + finishing). Traditional brick-built house: 9 to 14 months. In both cases, an additional 3 to 6 months are needed for preliminary procedures (permits, soil study, artisan selection). The shipping container option thus saves about 6 months net, which is significant for a tight project schedule.
Is the durability equivalent?+
Over 50-80 years: the brick-built house wins (brick and block age well with minimal maintenance). Over 30-50 years: nearly equivalent, both require similar maintenance (roofing, waterproofing). Over 20 years: equivalent or shipping container ahead (steel structure very stable). The exterior paint of a shipping container needs to be repainted every 8-10 years (£3,150 – £6,300) whereas rendered brickwork lasts 20-30 years.
Thermal performance Building Regulations Part L with a shipping container?+
Achievable but demanding. Corten steel is a massive thermal bridge: it requires high-performance external insulation (sprayed PU 100 mm, U=0.20 W/m²K) + cladding. Insulation budget: £15,750 – £31,500 for a T3 of 75 m². A traditional brick-built house achieves Building Regulations Part L with standard internal insulation at lower cost (£10,500 – £21,000). In terms of pure thermal performance, the brick-built option is easier to comply with.
What resale value does a shipping container home have?+
The used container market exists but is more limited. For a carefully converted unit, there is usually a discount of 5 to 15% compared to the equivalent brick-built property with similar surface area and location. Main obstacles: market culture (buyers not well informed), sometimes harder bank financing, refusal of zero-interest loans. This is evolving rapidly — the container is gaining legitimacy each year.
Can a shipping container house be built on a plot in a standard PLU zone?+
Yes, with exceptions. Urban (U) and urbanisation (AU) zones generally accept the shipping container house under a building permit. Agricultural (A) and natural (N) zones are often restrictive, sometimes prohibitive. Some coastal or mountain municipalities impose strict regulations (mandatory wooden cladding, height limits). Consult the PLU and/or request an urban planning certificate before purchasing the land or the container.
