"Loft Conversions in 2025: What UK Homeowners Need to Know"

With rising property prices and space at a premium, loft conversions remain one of the smartest investments for UK homeowners in 2025. Whether you need an extra bedroom, home office, or studio, converting unused attic space can dramatically increase both functionality and value.

At MMK Construction Ltd, we specialise in high-quality loft conversions across South West England. Here's what you need to know before starting your project.

1. Why Loft Conversions Are Still a Top Choice

• Cost-effective expansion: Cheaper than moving house.

• Increases property value: Adds up to 20% in some cases.

• Planning permission often not required under Permitted Development.

2. Types of Loft Conversions

• Dormer Conversion: Adds vertical space and natural light.

• Hip-to-Gable: Ideal for semi-detached homes.

• Mansard: Maximises space, often used in terraced homes.

• Velux/Skylight: Most affordable option.

MMK Construction will advise on the best type for your home’s structure and your goals.

3. Key Regulations & Considerations

• Building regulations approval is always required.

• Fire safety, insulation, headroom, and access all matter.
