When it comes to extending the home, many homeowners will need to comply with Building Regulations. However, with the right know-how, you can always ensure you’re fully compliant with them, so you will not run into any difficulties later down the line.
Conservatories with a 75% translucent roof and 50% glazed sides are exempt from Building Regulations provided that:
Therefore, if you’re hoping to add a glass roof conservatory or garden room to your home and they abide by the guidance above, Building Control approval will not need to be sought.
According to LABC guidelines, if work is carried out on a conservatory that significantly reduces the amount of glazing or how translucent the roof is, it will no longer be considered exempt from Building Regulations. Therefore, if you’re planning to build a tiled roof conservatory or you’d like to retrofit a tiled roof to an existing one, it will need to have certified Building Control Approval.
However, we submit any Building Control notices to the relevant local authority before work begins and once it has finished, we'll also supply a Building Regulation Approval Certificate as proof that your structure is fully compliant with the necessary regulations.LABC Guidance on Tiled Roof Conservatories
In order to comply with Building Control approval, the roof being fitted will need to match the thermal performance that is specified for roofs on new-build properties, which is a U-value of 0.18 W/m2k. Fortunately, our NuRoom tiled roof system is able to meet this specification.
In addition to this, the existing structure must also not be worsened in any way. This means that the existing building’s window frames and foundations have to be proved adequate to support the roof.
Therefore, the solid roof, suitability of the frames and foundations require approval under Building Regulations. However, other elements of the design do not fall under them as long as they do not exceed the usual guidance that enables a conservatory to be exempt from Building Control (listed above).
Any new structural opening between the conservatory and the existing house will also require building regulations approval, even if the conservatory itself is an exempt structure.
