Why choose a loft conversion?

​

A loft conversion is a cost-effective way to create extra living space without moving. With the right design, your attic loft conversion can become the perfect spot for a master suite, guest room, or even a creative workspace.

 

Types of loft conversions

 

There are several types of loft conversions to suit different homes and needs:

 

• Dormer loft conversion: Adds a box-shaped extension to your roof, creating more headroom and usable space

• Velux loft conversion: Uses skylight windows in the existing roof, ideal for spaces with enough height

• Hip-to-gable loft conversion: Extends the sloping side of a hip roof to create a vertical wall, maximising space

• Mansard and modular loft conversions: Major structural changes for the biggest increase in space

 

We’ll help you choose the right approach for your property, whether you’re considering a dormer loft conversion, extension loft conversion, or a simple attic loft conversion.

 

What does a loft conversion involve?

 

Every loft extension starts with a detailed design and feasibility study. We look at your roof structure, available space, and what you want to achieve.

 

Our team handles architectural planning, building regulations, and all the drawings needed for a smooth build. We work with trusted local contractors in Dorchester and across Dorset to ensure your loft conversion is built to the highest standards.
