Loft Conversion Structural Calculations

Loft conversions have become a popular choice with homeowners who would prefer to stay where they are but need a bit of extra elbow room to accommodate a growing family, or to create a comfortable home office to allow them to work from home.

A lot of people are now realising that having a loft conversion can work out much cheaper than selling up and moving house, so if you love where you live and get on well with your neighbours, then this is a very viable option.

However, having a loft conversion isn’t always as straightforward as you may believe. Depending on the type and build of your home, your loft may not have been built to take a full domestic load. So you may have more work to do than you first thought.

How GL Design Services can help

Working out your loft conversion can be a bit of a headache, but by bringing in our highly knowledgeable and experienced team, we can thoroughly inspect your loft and the structural capabilities of your existing floor, joists and ceiling to see what work needs to be done.

You will also need to add a staircase into your new loft space so we can calculate and factor in all the new floor joists and trimmer joists needed to fit around the new aperture.

We will also take into consideration your roof design and talk to you about how you would like to light the space. This could be by installing dormer windows for example, but no matter what style of window you want we will check to see if it is a viable choice and will calculate any dormers, partitions and beams needed to support the structure.

It may be that your ceiling joists were designed to carry a much lighter load than what you plan for your loft. In this case, we can do the calculations for stronger joists and flooring needed to make the space usable for your needs.

Steel beam calculations

In most cases of loft conversions, you will need to have a steel beam installation to carry the new weight of the floor where you don’t have any load-bearing walls. We will do all the structural steel beam calculations and calculations for the bearing pad stone.

Depending on your plans for the roof space, you may also need steel support beams to take the weight of your modified roof and the additional glazing you wish to add.

It is usually the case that you will need steel beam supports when you want to add dormer windows,  such as a structural ridge beam. We can do the calculations for all the steel beams you need to support your conversion plans.

Utilising existing features

Depending on the age and structure of your home, it may be that you have existing load-bearing walls running right up to the top of your roof. In these cases, it can be possible to utilise these load-bearing walls to support new, stronger loft flooring.

However, should there be any doubt about the strength and integrity of the existing walls, it is always wise to play safe and use steel supports. All of these things will be considered and worked out with our fully comprehensive loft conversion calculations service.

If you are considering adding a loft conversion to your home, then do not hesitate to get in touch with us to discuss your ideas. We are happy to answer any questions you may have and can give you some sound advice about the viability of the job.
