Loft Conversions

Our professionally qualified structural engineers can help establish the suitability of your loft space to create a safe and practical design for your home. 

We can advise on and produce structural drawings and calculations for both roof window and loft dormer conversions.

How we can help:


We can offer the following services:

  • Make a site visit if necessary

  • Initial design and advice on structural layout, including the alterations required to allow conversion

  • Undertake the structural design of the elements required - considering both the strength and stiffness requirements

  • Check the lateral stability of the structure

  • Prepare a set of drawings and specifications showing the structural requirements

  • Prepare a set of calculations that should be submitted to building control or an approved inspector​

  • Design any steelwork connections and new structures required

With Modulus, you will always receive a high quality and bespoke service. Our team of experienced engineers will work alongside you to provide practical and cost effective solutions to deliver your project to your requirements.

If you have a loft conversion which requires a structural engineer, contact our team today.

COVID-19 (Coronavirus) Update:

For some of our projects we recommend site visits. Based on the latest Government advice we consider these can still be undertaken as they are an essential part of our service. However, if you have any concerns about a site visit, please discuss this with us as we can find alternatives to allow our structural design to be carried out.
