I want to build my own house, what do I need to know?

Research indicates that more than half of the population would like to build their own home at some point in their lives. While it is a significant commitment that demands time and dedication, the reward is a home designed specifically to suit your needs and lifestyle.

As part of the self-build journey you will have to consider many factors including:

  • Finance
  • Location and acquiring land
  • Modular homes
  • Planning permission.

Common Questions

Do I need to apply for planning permission for a pergola?

A pergola is classed as permitted development, meaning an application for planning permission is not required provided it meets specified conditions and limits.

Outbuildings cannot be installed on the principal elevation of the property, additionally any platform must not exceed 0.3 metres in height.

If the building is listed, then you will need to apply for listed building consent and planning permission for the change.

For more details read our outbuildings common project.

Can I upgrade my windows and doors to reduce heat loss?

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.

What are the planning and building rules for constructing a soakaway?

A soakaway does not normally require an application for planning permission provided it deals with surface water and does not discharge into a public sewer. Additional regulations may apply if you are in a conservation area or within the boundary of a listed building.

Building regulations will apply to the creation of a soakaway. The soakaway must comply with Part H of the building regulations which specifies where they can be located and the size that is permitted.

Do I need planning permission to erect a veranda?

Verandas will often require planning permission as they do not fall under permitted development rights. If the veranda is raised over 0.3 metres, covers more than 50% of the land around your house, is on the principal elevation or on a roof then it will need planning permission.

You may require additional consents if you live in a Conservation Area or listed building. If you are unsure, you should contact your local planning authority.

For more information about planning permission for verandas and balconies, read our common project.

Do I need planning permission to convert my garage into a workshop?

If the garage will remain in domestic use - for example, as a personal hobby or home workshop - then planning permission is typically not required.  

However, it’s important to check whether there are any planning conditions, covenants, or restrictions attached to your property or the garage itself that may limit or prevent conversion.
