Attic trusses are a versatile and cost-effective method of adding both living space and value to your property. In line with the Code for Sustainable homes, the ‘room-in-the-roof’ concept makes use of often wasted attic or loft space. If you are considering an extension to your home or enhancing a building design, it is often cheaper and more practical to utilize the roof space than it is to increase the building footprint.
Melingoed will work with you to design attic living space that is both aesthetically pleasing, practical and within budget. Loft conversion using attic trusses provides all the benefits of an engineered trussed rafter solution, allowing you to create visually stunning living environments.
Attic Trusses increase the habitable area of your home
- Increased living space without changing the footprint
- Reduced build costs per square metre.
- Flexibility of living space without expensive build-on costs
- There are no restrictions on lower floor or roof layouts since attic trusses may be designed to clear span onto external load-bearing walls.
- Complex, labour intensive site work is eliminated.
- Lowermost members of trussed rafters automatically give floor platform.
- Once trussed rafters are erected the roof is complete, ready to receive roof finishes, plasterboard and floor boarding.
Planning an attic roof or loft conversion:
As with any housing project, careful planning can avoid problems later. Here are some points you need to consider when considering that loft conversion or attic roof:
- Simple loft conversions generally do not require planning permission, particularly of there is no change to the original roof line. However you are advised to consult with your local planning department, especially if your home is a listed building or in a conservation area.
- Structural elements such as beams and lintels over openings must be checked to be sufficiently load bearing.
- Internal walls to be used as supports must be verified as load bearing.
- Sufficient space is available for access, especially planning staircases.
- Fire safety regulations are adhered too (fire-proof escape route, 30 minute fire proofing, fire doors etc).
- The required insulation and acoustic specifications are incorporated.
Forming the Roofscape – Attic Truss Good Design Practice
- Stairwell and window openings are formed by placing multiple girders each side of the openings and framing in between. Where possible place stairwells parallel to the trusses and position windows opposite each other.
- For T-intersections or ‘walk-throughs’ consider a corridor link between the room areas. This will reduce the site framing required. It may also allow the use of a girder truss in cases where load bearing walls are not present.
- Make use of loadbearing internal walls to add extra support for the attic trusses. To be most effective place the bearing within the centre fifth of the of the span, the mid-span having the most influence.
Attic Trusses and our Roof Package
Melingoed design and engineer attic trusses for the most demanding of projects. Where necessary existing structural elements must be checked for suitability and if required upgraded. Often new beams and supports need to be added to existing buildings. Our design service can specify steel or glulam beams to be incorporated as part of a fully engineered solution to your project.
