The Benefits of Loft Conversions

Maximise Space

Loft conversions make use of existing space, eliminating the need for extensions that encroach on your garden or exterior areas.

Whether you need an extra bedroom, home office, or playroom, a loft conversion provides a versatile solution without altering the footprint of your home.

Increase Property Value

Investing in a loft conversion can significantly boost your property's market value. On average, a well-executed loft conversion can increase your home's value by up to 20%.

This makes it not only a practical choice for your living needs but also a smart financial investment.

Our Loft Conversion Process

We start with an in-depth consultation to understand your needs, preferences, and budget. Our experts conduct a thorough feasibility study to assess the structural integrity and potential of your attic space.

During this phase, we discuss your vision, provide initial design concepts, and outline the scope of the project.

Our talented designers work closely with you to develop detailed plans that maximise the use of space while aligning with your aesthetic preferences.

We handle all planning permissions and building regulations, ensuring a hassle-free process. Our designs include structural plans, electrical layouts, and high-quality 3D visualisations.

We handle all planning permissions and building regulations, ensuring a smooth and compliant process.

Transparency and accuracy are key to our costing process. We provide a detailed breakdown of all costs involved, ensuring there are no hidden surprises.

Typical costs for a loft conversion can vary depending on the size, complexity, and specifications. On average, the cost ranges from £30,000 to £60,000 for a standard dormer conversion, while more complex projects, such as Mansard conversions, can range from £45,000 to £70,000.

Our comprehensive quotations include all aspects of the project, from design and materials to labour and project management.

Once the design is finalised and approved, our skilled construction team takes over. We manage every aspect of the build, ensuring high standards of workmanship and adherence to timelines.

Regular site visits and updates keep you informed of progress, and our project managers are always available to address any concerns or changes.

Upon completion, we conduct a thorough inspection to ensure everything meets our exacting standards and your expectations.

We provide a complete handover, including all relevant documentation, warranties, and maintenance advice to ensure your new loft space remains in top condition.

Types of Loft Conversions and Their Costs
Loft conversions are a fantastic way to unlock the potential of your home, providing additional space without the need for a costly move. Whether you need an extra bedroom, home office, or additional living area, there are several loft conversion options to suit different property types and budgets.
Roof Terrace Loft Conversion
z
Where planning restrictions limit traditional loft extensions, a roof terrace can be an excellent alternative. Built over the rear addition of a home, it provides valuable outdoor space, particularly for flats or maisonettes lacking a garden.

Typical cost: £30,000 – £50,000
Skylight Loft Conversion (Velux Loft Conversion)
z
A skylight or Velux loft conversion is the most straightforward and budget-friendly option, as it does not require altering the roof structure. This conversion simply adds Velux windows to bring in natural light, making it suitable for lofts with sufficient headroom. It is an ideal solution for conservation areas where dormer extensions are not permitted.

Typical cost: £27,500 – £40,000
Pod Dormer Loft Conversion
z
A pod dormer is a small extension that adds extra headroom to an existing dormer loft conversion. Often part of an L-shaped dormer conversion, pod extensions are common in Victorian and Edwardian properties, allowing for additional storage or a compact extra room. They provide a cost-effective way to maximize space without requiring a full loft rebuild.

Typical cost: £30,000 – £50,000
Mansion Block Loft Conversion
z
Mansion block loft conversions are designed for top-floor apartments within period mansion blocks. These conversions require specialist planning and structural considerations to comply with leasehold agreements and building regulations. When executed correctly, they add significant space and value to a flat while preserving the character of the building.

Typical cost: £50,000 – £80,000
L-Shaped Dormer Loft Conversion
z
Common in Victorian and Edwardian properties, this conversion combines two dormer builds to form an "L" shape, maximizing space in period homes with rear extensions. It allows for multiple rooms, making it one of the most practical and value-enhancing conversions.

Typical cost: £45,000 – £60,000
Hip-to-Gable Loft Conversion
z
Perfect for semi-detached and detached homes with a hipped roof, this conversion straightens the slanted side to form a vertical wall, significantly increasing usable space. It is ideal for creating an additional bedroom, office, or en-suite.

Typical cost: £42,000 – £65,000
Mansard Loft Conversion
z
Mansard conversions involve significant structural changes, altering the sloping roof to create a nearly vertical rear wall. This maximizes internal space and provides a large, open-plan layout, making it ideal for adding multiple rooms. Commonly found in terraced houses, mansard conversions usually require planning permission due to the structural changes.

Typical cost: £45,000 – £70,000
Dormer Loft Conversions
A dormer loft conversion extends vertically from the existing roof, creating additional headroom and floor space. This is one of the most popular and cost-effective loft conversions, often falling under permitted development rights, meaning planning permission may not be required. Suitable for most property types, it allows for a well-lit and spacious room.

Typical cost: £30,000 - £60,000
