Loft Conversions

A loft conversion is one of the most cost-effective ways to add living space and value to your home. Structural engineering input is essential to ensure the conversion is safe, compliant with building regulations and designed to last. Offset Engineering provides comprehensive structural engineering services for all types of loft conversion across the UK.

Types of Loft Conversion We Design

We provide structural engineering for all types of loft conversion, including rooflight conversions, dormer loft conversions, hip-to-gable conversions and mansard conversions. Each type requires a specific structural approach, and our engineers are experienced with all common roof construction types found in UK residential properties.

Structural Requirements for a Loft Conversion

A loft conversion typically involves modifying the existing roof structure to create headroom, installing new floor beams to support the loft floor at an appropriate load-bearing capacity, and strengthening or modifying the existing structure as required. Where a dormer or other external alteration is proposed, the structural design must accommodate the additional loads and wind forces involved. All works require building control approval.

Working with Architects and Contractors

We regularly work alongside architects, planning consultants and building contractors to deliver loft conversion projects efficiently. Our calculations and drawings are prepared in a format that is immediately usable by your project team and building control, minimising delays and queries. We are always available to discuss technical matters with your architect or contractor throughout the project.
