Attic Room/Space

Attic or room in the roof trusses are becoming increasingly popular because they provide additional living space without affecting the footprint of the building, offering maximum value to the builder and homeowner.

These intelligently built trusses incorporate a lower component that serves as a floor platform.

The benefit of this is that the attic trusses can span onto external load-bearing walls, providing additional flexibility in roof and lower floor layouts depending on span and room size.

The lowest chord of the truss, which becomes the room’s floor joist, can be designed and built in a variety of ways.

Attic trussed roofs can be created with openings for stairwells, roof-lights, and dormer windows, with attic trusses nailed together on-site to give support for any openings required in the roof design.

Attic trusses are built the same way as conventional trusses, but are built to accommodate home floor loadings as well as form the habitable part for the room.

In addition to the dimension requirements, they will require information about any other features you may be contemplating for your attic space that would have an impact on the truss design, such as roof lights or a dormer window to add light to your space.

What Are the Benefits of An Attic Truss?

Attic trusses serve as both a structural roof and a floor – a double edge sword! This means that there is more living space without having to change the house’s footprint.

The use of this space results in a lower cost per square meter of construction.

The full utilization of the loft area provides some wonderful benefits for both the homeowner and the builder performing the work.

The entire roof structure can be built offsite and delivered at the appropriate time. This will be ready for you to put in your floorboards, finish the space, and install plasterboard walls.

As the cost of land continues to rise, an increasing number of people are making use of attic space. A room added to a roof is much more than a simple attic conversion.

Trusses are “designed” for specific “loads” and are utilized to reduce the quantity of lumber and other material used in the roof “system.”

If you mean converting a truss attic into a living or storage space, the answer should be addressed by an architect or engineer who has access to your blueprints and a clear understanding of what you’re proposing.

The trusses would have to be rebuilt that is made strong enough to support the added weight from adding an attic floor and heavier ceilings below.

Other things like heating systems, insulation, beam enclosures, etc., would need substantial additions or changes in order to properly insulate and heat new living space — beyond making changes just for additional living space/heating requirements on top of existing system limitations.
