Are you considering adding a loft in your residential property? Well, loft conversions or simply an attic conversion may involve extensive labour and capital requirements. However, merely a roof extension or attic conversion to add a living space can cost around £3,700 to £11,500, depending on the size and design. But, for full-fledged loft conversions, whether it's loft remodelling or loft renovation, can cost from £11,500 to even £55,000, giving an average of $35,000 range. Understanding the cost variations and the factors involved is necessary before going into loft conversions to help you make an informed decision regarding your property.
So your decision is final? Let’s get into it then. The average cost of loft conversions varies between £11,500 to £55,000. However, a lot of factors affect the cost range. It is important to understand each of them for you to make a precise blueprint of what exactly you want from this project, as per your budget.
Here are the factors that affect the range of the loft conversion cost:
First of all, we have the complexity and the size of the loft conversions. From simple renovations to full-blown remodelling, and simple roof extension to proper attic conversion, every little detail makes a difference. Here is an estimated cost:
Complexity of Loft Conversions | Estimated Cost |
Simple | £11,500 |
Medium | £34,500 |
Hard | £55,000 |
Moreover, if we talk about price variations between renovation vs. remodelling. Here’s an estimate of that:
Loft Conversions | What Does It Include? | Estimated Cost |
Renovation | Minor changes to add up storage or living space | £7.500 - £26,000 |
Remodell | Structural and layout changes for proper attic conversion | £12,000 to £45,000 |
Another major factor affecting the cost of loft conversions includes the type of conversion you’re going with, whether it is a dormer loft conversion or simply a dormer extension, a mansard loft conversion or simply a mansard roof extension, or a hip-to-gable loft conversion.
Here is a detailed analysis of loft conversions and their price range.
Types of Loft Conversions | What Does It Include? | Estimated Cost |
Dormer Loft Conversion |
| £65 to £160 per square foot |
Hip-to-Gable Loft Conversion |
| £180 to £400 per square foot |
Hip-to-Gable Loft Conversion |
| £250 to £400 per square foot |
Mansard Loft Conversion |
| £50 to £250 per square foot. |
Building on the size, complexity, and type of conversion, another significant factor is the material. What type of material is used, its quality and availability in the market. All these factors play a major role in deciding the total cost of the conversion process. High-quality materials will automatically increase the cost of the project. So, choose your materials and their usage wisely.
One of the most significant factors affecting the loft conversion cost is how you’re going to use that space. Whether you need it for personal usage or want to make a home office workspace, whether you want to include an attached bathroom or just want a simple renovation, whether you need HVAC services or not, all these factors play a major role in deciding the cost of the loft conversions.
Here’s the cost of extra services you may or may not add in the process:
Additional Service or Usage | Estimated Cost (per square foot) |
Simple Storage | £25 to £85 |
Bedroom | £50 to £250 |
Bedroom with an attached bath (includes plumbing) | £70 to £350 |
Home Office | £45 to £100 |
HVAC Service | £1,500 to £10,500 |
Here’s a list of other labour-related costs that you need to keep in mind:
Additional Costs | Estimated Price |
Plumber Costs | £1,200 to £3,000 |
Carpenter Cost | Around £30 to £35 per hour |
Labour Cost | £150 to £400 per day per worker |
Architecture’s Cost (optional) | Around 5% to 15% of the total project cost |
Permit Fee | £400 to £1,500 |
However, did you know that if your loft conversion impacts a shared wall, you'll need to notify your neighbours? And you also need to hire a party wall surveyor? Yes. You can thank us later. This can cost you around £700 to £1,500, or more if disputes arise.
Thus, the cost of loft conversions depends on the size, complexity, purpose of usage, type of conversion, material used, along with major services and labour costs that you need to be mindful of. Before taking any final decision, make sure to consult all the information given above or a local contractor who can guide you throughout the project.
