Frequently Asked Questions

Are garden rooms permitted development?

Garden rooms may qualify if they meet size and usage limits and are not used as separate accommodation.

How high can my extension be?

Height limits vary, but rear extensions under permitted development generally cannot exceed four metres for detached houses or three metres for others.

Can I extend a house that has already been extended?

Permitted development limits are cumulative, so previous extensions may reduce what is still allowed.

Do I need planning permission for a rear extension in Newbury?

Many rear extensions fall within permitted development limits, but projection depth, height, and boundary proximity must comply with national rules and any local restrictions.

How long does a Lawful Development Certificate take?

Most councils determine applications within eight weeks, though timescales may vary.

What is the maximum size allowed under permitted development?

Size limits depend on property type and location. Detached houses may have larger rear extensions than terraced homes, subject to height and boundary constraints.
