Increase the size and value of your property
A loft conversion is the perfect way to increase the size and value of your home. Not only does a professionally installed conversion make a great addition to your home it will also add value to your property.
Further information below regarding loft conversions
If you are thinking of converting unused loft space to a habitable living space then the work that is completed needs to be completed to building control standards. The local council have a building control department and they come and check that all work completed is done so to the latest regulations.Building control ensure that alterations are carried out correctly so they do not cause problems at a later stage. For example, there could be problems in selling your home if changes are not noted in your house plans or a structural problem results from use of inadequate materials.
As professional builders, we must consider:
- Structural Stability
- Fire Resistance
- Access and Means of Escape
- Weather Resistance and Energy Conservation
1. Structural Stability
If the space is for use other than light storage then a new floor will have to be provided. The existing ceiling joists are not designed for heavy loads. Any alterations to the roof structure such as skylights or dormers require careful consideration so they do not adversely affect the overall stability of your roof. This includes assessing load baring walls – their construction and foundations. Any structural members, e.g. beams, beam bearings, posts, trimmers and connection details must be justified by calculations.
2. Fire Resistance
UK Building regulations require loft floors and certain walls and doors to resist fire for a specified period (usually 30minutes). The correct form of construction will protect occupants in the conversion for this period. Staircases need to be enclosed by construction (doors and walls or partitions) with 30 minutes fire resistance, or, existing doors retained, if not glazed and self-closing. En Suite bathroom or toilet doors need not be fire resistant. The condition of existing doors and doorframes are assessed. The installation is to comply with BS5446: Part 1: 1990 or BS5939: Part 6: 1995 with regards mains powered smoke detectors. The dormer roofs need to be capable of resisting external fire spread for at least 30 minutes.
3. Access and Means of Escape
Access to the converted loft is via a flight of stairs and you need to consider the type of stair you require. Traditional strait stairs will give safe and easy access, however other types are available such as double and triple kite wind and others will tend to gain approval where space is restricted. Stairs also provide a safe escape route for occupants in the event of a fire. For two storey houses. Building Regulations give specific advice on the loft conversions in these situations. Particularly, the route must discharge to an external door – the staircase must discharge close to a door leading to an external safe place and not in a room. Escape windows such as the VELUX® escape/access skylights are no longer required and are optional – they are designed to be large enough to escape through, and positioned for easy rescue by ladder.
4. Weather Resistance and Energy Conservation
The loft walls and roof must keep out the elements and retain heat. The materials we use in construction are designed to reduce heat loss. This will conserve energy and cut your fuel bills. External loft walls are constructed to achieve a U-value of not more than 0.35W/m2oK, and roof areas to achieve a U-value of not more than 0.30W/m2oK.
Building regulations provide guidance on ventilation so a health living environment is created. Ventilation provides clean air to the living environment and vents moist or stale air, which would cause condensation. Ventilation is also required under the roof tiles, again to prevent condensation that would not be seen or detected before it caused serious problems. Ridge vents to a continuous 5mm gap and eaves vents to a continuous 25mm gap are built in front and rear – unless a vapour permeable sarking layer (breather felt) is used.
