Inefficient windows and doors can significantly contribute to heat loss. Replacing single glazed windows by installing double glazing can cut heat loss through windows considerably. Double glazing works by trapping air between two panes of glass creating an insulating barrier that reduces heat loss, noise and condensation.  

‍

If you can't replace all the windows, why not choose the rooms that cost you the most to heat? Other options to reduce heat loss through windows include sealing gaps or using thermal blinds.

You don’t usually need planning permission for repairs, maintenance and minor improvements or replacing windows and doors that are of a similar appearance.

‍

Building regulations apply to replacement glazing, in terms of thermal performance, air supply, ventilation, safety and means of escape.

A single storey rear extension can fall under permitted development, meaning planning permission may not be required providing it meets certain criteria.  

In terms of height, the extension must:

• Be no taller than four metres at its highest point

• Have eaves no higher than the eaves of the original house

• Not exceed the height of the original dwelling

Bricking up an external door is classified as permitted development, meaning an application for planning permission is not required to complete the works. You will need to ensure that any materials used are of a similar appearance to the existing exterior of the house.

If you live in a listed building, then you will require planning permission and listed building consent for the change. In this instance it is best practice to talk to your local planning authority.

Adding a personal or commercial glamping pod will often require planning permission due to the size and permanence of the structure.

For personal use, whether you require planning permission depends on the size of the structure. If it’s placed in your garden, then it may be classed as an outbuilding and fall under permitted development rights. This only applies if it is not treated as a new living space which many glamping pods will be. Full details on outbuildings are available on our common project pages.

For commercial use, planning permission will be needed for the addition, where relevant this will also cover the change of use. An application should include any utilities connections or access roads that will be added alongside the pod.

Due to the complex nature of installing a glamping pod, we’d recommend talking to your local planning authority or our Planning Guidance Service.

Adding a porch canopy is classed as permitted development provided it meets the limits and conditions set out in legislation. Where this is the case, no application for planning permission is required.

Porches must meet the following limits:

• the ground floor area (measured externally) would not exceed three square metres.
• no part would be more than three metres aboveground level (height needs to be measured in the same way as for a house extension).
• no part of the porch would be within two metres of any boundary of the dwellinghouse and the highway.
