Bathroom regulations in Scotland

Bathroom design regulations

There is a lot to think about when either re-designing your bathroom, removing your ground floor bathroom or having a completely new bathroom in your home/extension.

If you are designing a new ground floor bathroom and there is not one already on the ground floor, then this will need to be accessible in terms of the regulations. The main criteria for this is 1100mm space clear of any door swing (typically the door will open outward to reduce size of bathroom), 800mm x 1100mm in front of WC, 700mm x 800mm in front of wash hand basin and 800mm x 800mm in front of bath/shower.

In a nutshell, you can’t remove a ground floor bathroom without providing an equivalent somewhere else on the same level.

Conservatory roof conversion

 

DID YOU KNOW?
If you change a conservatory roof with a lightweight tile such as a Metrotile, this becomes a sunroom in terms of regulations.

WHAT DOES THIS MEAN?

Conservatories are allowed to be built over a habitable room such as lounge/bedrooms, however if converted to a sunroom then the lounge/bedroom should have another window/door to the external elsewhere. Alternatively, you can design the sunroom to be open plan with approx. 25% glazing plus the opening that is built over.

SOUND COMPLICATED?

Architects can advise you/builder and do all calculations/drawings for building regulations.

HOW MUCH DOES A CONSERVATORY ROOF CONVERSION COST?

The costs can vary depending on size, however a 4m x 4m conservatory would cost approx £5-6k for a basic conversion.

The cost can be influenced by many factors including; if the existing frame can be kept or removing to install a new roofing frame, what insulation can be used such as rigid insulation or products such as Superquilt, new heating and electrics.

WHY CHANGE YOUR CONSERVATORY TO A SUNROOM?

Most people's reason for wanting to change their conservatory to a sunroom is due to being too hot in the summer and too cold in the winter, however a solid insulated roof helps retain the heat in the winter and helps keep the room cool in the warmer months.

WHAT PERMISSIONS DO I REQUIRE?

In most cases you will at least need building warrant approval which involves providing the local authority with plans, U Value calculations, data sheets and structural engineers SER certificate/plans, however you may also require planning permission.
