Loft Conversion Cost

Converting a loft is a popular way to add both space and value to your home. There are several types of loft conversions, each with its own benefits and costs. This guide, advised by NG Construction Team Ltd, will take you through the process, different types of conversions, and their estimated costs.

1. Initial Considerations

First and foremost, it is crucial to ensure that your loft is suitable for conversion. Key aspects to consider include the height, structure, and type of roof. Typically, you will need a minimum height of 2.2 metres for a loft conversion to be viable.Not all loft conversions require planning permission, but some do, especially if you are making significant changes to the roof structure. It is essential to check with your local council to determine if planning permission is necessary for your project.Regardless of whether planning permission is needed, all loft conversions must comply with building regulations. These regulations ensure that the conversion is structurally sound and safe, covering aspects such as fire safety, insulation, and ventilation.

2. Planning and Design

 Hiring an architect to create detailed plans for your loft conversion is a crucial step. These plans will not only help you visualise the final result but are also necessary for obtaining planning approval if required. If your loft conversion needs planning permission, you will need to submit your plans to the local council for approval. This process can take several weeks, so it is essential to factor this into your project timeline.

3. Budgeting and Financing

• Cost Estimates:
  • Dormer Loft Conversion: £30,000 - £40,000. This type of conversion involves extending the existing roof to create additional floor space and headroom.
  • Hip-to-Gable Loft Conversion: £40,000 - £50,000. This type involves changing the sloped side of the roof (hip) into a vertical wall (gable), effectively extending the roof space.
  • Mansard Loft Conversion: £50,000 - £80,000. This type creates a flat roof with a slight slope, usually at the rear of the house, and involves significant structural changes.
  • Velux Loft Conversion: £20,000 - £30,000. This type involves adding Velux windows to the existing roof without altering its shape.
  • L-Shaped Loft Conversion: £50,000 - £75,000. This type involves building an L-shaped dormer, which can provide two rooms and a large floor space.
• Financing: Consider how you will finance the conversion. Options include home improvement loans, remortgaging, or using savings. It is essential to have a clear budget and to account for potential unexpected costs.

4. Construction Phase

• Structural Changes: Reinforcing the floor, adding supports, and installing any necessary new roof structures are essential steps in the construction phase. These changes ensure that your loft conversion is safe and structurally sound.
• Windows and Insulation: Installing new windows, such as Velux windows for dormers, and ensuring the loft is properly insulated are crucial for creating a comfortable and energy-efficient space.
• Electrics and Plumbing: Installing new electrics and plumbing as needed is another essential step. This may involve adding new wiring, sockets, lighting, and, if you are adding a bathroom, plumbing fixtures.
• Internal Finish: Completing the interior with plastering, flooring, and installing fixtures and fittings brings your new loft space to life. This stage includes painting, decorating, and installing any additional features such as built-in storage.

6. Final Touches and Inspections

 Once the construction and internal finishes are complete, it is time to paint and decorate your new space to your taste. This step allows you to personalise your loft conversion and make it feel like a part of your home. Ensuring all work complies with building regulations and getting it signed off by an inspector is the final step. This sign-off confirms that the conversion meets all necessary safety and quality standards.
