Attic or loft conversions come in various types, each offering its own set of benefits and cost considerations. Expenses may rise due to factors such as incorporating luxurious finishes, increasing the number of windows, constructing a new staircase, selecting specific flooring, and installing a bathroom.
Additionally, the overall costs are influenced by the project’s location and the weather conditions. Adverse weather can lead to delays in the project’s timeline.
Below, we’ll explore the typical costs associated with different types of attic conversions in the UK.
1. Velux Conversion:
A Velux conversion, also known as a roof light or skylight conversion, is one of the most cost-effective options for converting your attic space. It involves adding roof lights or skylights to an existing attic without altering the roof’s structure significantly.
On average, a Velux conversion for a 20 m2 can cost between £15,000 to £25,000, depending on the size of the attic, the number of roof lights required, and any additional features such as insulation and flooring.
2. Dormer Conversion:
Dormer conversions are popular because they provide additional headroom and floor space by extending the existing roof vertically. There are different types of dormers, including flat roof, gable-fronted, and hipped roof dormers, each with its own cost implications.
Dormer conversions for a 20 m2 typically range from £20,000 to £40,000, depending on the size and complexity of the dormer, as well as any structural alterations required.
3. Hip-to-Gable Conversion:
A Hip-to-Gable conversion involves extending the hip roof to create a gable end, providing more internal space. This type of conversion is ideal for properties with a terraced and hipped roof design.
Hip-to-gable conversions for a 20 m2 can cost between £30,000 to £50,000, depending on the size of the attic, the extent of structural work required, and any additional features.
4. Mansard Conversion:
Mansard conversions are the most complex and expensive option, as they involve changing the shape of the roof to create a nearly vertical wall. However, they can provide the maximum amount of additional living space.
Mansard conversions are often the most expensive. For a 20 m2 ranging from £40,000 to £70,000 or more. The high cost is due to the extensive structural alterations and custom design required for this type of conversion.
5. Bungalow Conversion:
Converting the attic space in a bungalow can be a great way to add extra living space without extending the footprint of the property. Bungalow conversions may involve various types, including Velux, dormer, or Mansard conversions, depending on the property’s design and structural constraints.
Bungalow attic conversions for a 20 m2 typically range from £20,000 to £50,000, depending on the type of conversion chosen and the size of the attic space.
6. Modular Conversion:
Modular loft conversions involve prefabricated units that are installed onto the existing structure, minimizing disruption and construction time. These conversions can be a faster and more cost-effective option compared to traditional methods.
Modular loft conversions for a 20 m2 can cost between £20,000 to £40,000, depending on the size and complexity of the modules, as well as any additional features required.

When converting a loft, choosing the right construction materials is crucial for achieving both structural integrity and energy efficiency. Here’s a breakdown of essential construction materials needed for a loft conversion, along with insights into their costs and environmental impact
Insulation is vital for regulating temperature and energy efficiency in the loft space. Common insulation materials include fiberglass, mineral wool, and rigid foam boards.
Insulation costs can vary depending on the type and thickness of the material. On average, expect to pay between £20 to £50 per square meter for insulation materials.
Opting for eco-friendly insulation materials such as recycled fiberglass or natural wool can reduce environmental impact. Additionally, proper insulation can lead to long-term energy savings by reducing heating and cooling costs.
The cost of windows depends on factors such as size, material, and glazing options. Expect to pay between £300 to £1,500 per window, depending on specifications.
Consider installing energy-efficient windows with double or triple glazing to improve thermal performance.
Energy-efficient windows can reduce heat loss and energy consumption, leading to lower carbon emissions and utility bills over time.
Common roofing materials include tiles, slates, and metal roofing. Roofing material costs vary depending on the type and quality of the material. On average, roofing materials can cost between £40 to £100 per square meter.
If you aim to enhance the sustainability of your project and home, consider utilizing recycled metal or clay tiles for your roof. Choosing recycled materials can frequently offer a more cost-effective option. Additionally, durable roofing materials can minimize the need for frequent repairs or replacements, saving money in the long run.
The cost of stairs depends on the design, material, and complexity of installation. Expect to pay between £1,000 to £5,000 or more for staircase materials and installation. Consider options such as spiral stairs or space-saving designs to maximize floor space in the loft.
When you choose and plan your staircase, you have the opportunity to integrate natural materials, encouraging sustainability in your design decisions. Moreover, you could consider reclaimed wood as an alternative, which may offer a more economical and environmentally conscious choice. Additionally, choosing space-saving staircase designs can optimize the use of space in the loft.
Fixtures and fittings include items such as lighting fixtures, plumbing fixtures, and hardware. Fixture and fitting costs vary depending on the brand, quality, and specifications. Budget between £500 to £3,000 or more for fixtures and fittings in a loft conversion.
Energy-efficient fixtures such as LED lighting and low-flow plumbing fixtures can reduce energy and water consumption, leading to long-term cost savings and environmental benefits.
General building materials include structural components, framing lumber, drywall, and finishing materials.
General building material costs can vary depending on the quantity and quality of materials selected. Budget between £5,000 to £20,000 or more for general building materials in a loft conversion project.
Opt for sustainable building materials such as FSC-certified lumber, recycled drywall, and low-VOC paints. Choose high-quality, durable materials that will ensure the longevity of your loft conversion. Additionally, durable materials require fewer replacements, reducing waste and resource consumption over time.
