How to Use This Calculator
Getting an accurate estimate for your brick garage project is straightforward with our calculator. Start by selecting your garage size – whether you’re after a standard single garage for one vehicle or a spacious double garage for two cars. If you’ve got specific dimensions in mind, choose the custom size option.
Next, pick your construction type. Brick garages offer the best longevity and value, whilst prefab options provide quicker installation. The roof type significantly affects both cost and appearance, with pitched roofs adding character but increasing expenses. Don’t forget to factor in your door preference and any extras like electricity or security systems – these can transform a simple storage space into a functional workshop or secure vehicle haven.
Once you’ve made your selections, click the calculate button to receive a detailed breakdown. The results show not just a total figure, but itemised costs for materials, labour, and each component, helping you decide where to invest and where you might save.
What Affects Your Garage Building Costs?
Several factors influence the final price tag of your brick garage. Size is the most obvious – a double garage naturally costs more than a single, but you’re getting better value per square metre. The construction material plays a huge role too. Standard bricks are more affordable than premium facing bricks, whilst breeze blocks offer excellent value when rendered.
Your location within the UK significantly impacts labour costs. Tradespeople in London and the South East typically charge 20-30% more than those in the Midlands or North. Site accessibility matters too – difficult access requiring smaller machinery or hand-carrying materials will increase labour hours and costs.
| Cost Factor | Budget Option | Mid-Range Option | Premium Option |

Brick vs Other Materials: Which Suits You?
Choosing between brick and alternative materials depends on your priorities. Brick garages offer unmatched durability, lasting generations with minimal maintenance. They’re also the best choice for adding property value, with estate agents confirming that brick outbuildings contribute more to home valuations than prefab alternatives.
Prefab options shine when speed matters. A metal or concrete prefab can be installed in under a week, compared to 2-4 weeks for brick construction. They’re also gentler on your budget initially, though factor in potential replacement costs – a well-built brick garage might still be standing when a prefab needs replacing.
Breeze block construction offers a middle ground. When rendered and painted, it’s visually indistinguishable from brick, provides similar structural strength and insulation properties, yet costs 30-40% less for materials. The trade-off is rendering requires repainting every 10-15 years, adding maintenance costs over time.
Planning Permission & Building Regulations
Most garage projects fall under permitted development rights, meaning you won’t need planning permission. However, specific conditions must be met. Your garage cannot be built forward of the principal elevation (the main front wall of your house), and height restrictions apply – maximum 4 metres for a pitched roof or 3 metres for any other roof type.
The garage mustn’t cover more than 50% of your property’s land area (excluding the original house footprint). If within 2 metres of a boundary, maximum height drops to 2.5 metres. Listed buildings, conservation areas, and properties with restricted permitted development rights require full planning permission regardless of size.
Building regulations always apply. Your garage needs proper foundations, adequate drainage, and if attached to your house, appropriate fire separation. Most builders handle building control notifications, but confirm this upfront. Expect building control fees of £200-£400 depending on your local authority.

Cost-Cutting Strategies That Actually Work
Timing your project strategically can save money. Builders are often quieter in winter months (November-February) and may offer better rates to keep crews working. However, weather delays might extend timelines, so spring and autumn offer the best balance of reasonable pricing and reliable weather.
Consider a simpler roof design. A flat roof costs 40-50% less than a pitched roof and is quicker to install. Whilst pitched roofs look more attractive and shed water better, a well-constructed flat roof with proper drainage performs perfectly well for most garages.
Reuse or recycle where possible. If demolishing an old garage or shed, salvageable materials like roof timber, doors, or concrete can reduce costs. Some builders offer discounts if you source certain materials yourself, though discuss this upfront to avoid issues with warranties or building regulations compliance.
What People Get Wrong About Garage Costs
The biggest mistake is underestimating total costs by focusing only on materials. A £2,000 brick kit sounds affordable until you add £3,500 labour, £800 for the foundation, £500 for the roof, and £300 for the door. Suddenly your £2,000 garage costs £7,100. Always get a complete breakdown including all elements.
Another common error is neglecting site preparation costs. If your chosen location has poor drainage, existing structures to remove, or requires significant levelling, add £500-£2,000 to your budget. Tree removal, underground service relocation, or challenging access can add thousands more.
Many homeowners overlook planning constraints until midway through the project. Check your property deeds for restrictive covenants – some estates prohibit outbuildings or dictate specific materials. Conservation area properties face stricter rules about appearance and materials, potentially increasing costs by 20-40% to meet requirements.
