Loft Conversion Structural Design

Here at Access Engineering, we specialise in loft conversion structural design. We understand that loft conversions are difficult and that most engineers overcompensate on beam sizes which is why we offer a comprehensive service that minimises cost, wastage and maximises productivity. 

  • We are a specialist in loft structural design
  • We don´t over specify beam sizes
  • Timber used where possible instead of expensive steel
  • Tailored design to suit your preferences

We wont over specify any beam. Our goal is to provide a pragmatic approach to loft design that’s feasible and most importantly buildable.

Dormer Loft Conversions

The most popular style of Loft Conversion, the Dormer is an extension that projects vertically from the existing roof to provide increased internal height and space.

Hip to Gable Loft Conversions

A Hip to Gable dormer extends the hip of your existing roof into a Gable end, creating a vertical wall. Popular in semi-detached and end terrace houses, this solution offers substantial internal space.

Mansard Loft Conversions

Best suited to terraced houses, the Mansard style extends the roof at an angle, and is often combined with Dormers. This solution generally offers the most height of the roof conversion styles.

Velux Loft Conversions

Typically the most affordable loft conversion, planning permission is not usually needed with a Velux conversion. If you have the roof height available, this offers the quickest conversion process.

A Rooflight conversion doesn't require any external structural alterations, instead adding Velux windows and reinforcing your loft floor to provide a new living space. This more affordable option requires over 2m of height in the middle of the room.
