Plans to convert an industrial building in Watford into 15 bedsits, seven of which would have no windows, have sparked controversy and anger over planning law.

But what does the law say?

Generally any development requires planning permission. However, there are some developments that Parliament has decided do not require formal planning permission. This includes most fences, porches, conservatories and small extensions. This is fairly non-contentious and saves the council having to deal with hundreds of planning applications for minor matters.

A few years ago, the coalition government decided that converting out of date or unwanted commercial buildings into residential properties would help ease the housing shortage. This was a controversial move and still is. It means that old offices can be converted without the need for the developer to provide affordable housing. It also means that local authorities can lose areas of employment.

However, local authorities can restrict this right in certain areas by passing an Article 4 Direction. Permitted development rights are also limited in conservation areas and areas of outstanding natural beauty.

What about building regulations?

Even if permitted development rights allow a development to proceed, it must still comply with the building regulations. These fix minimum standards for design, construction and alterations to virtually every building. They not only ensure that a building is habitable and safe to occupy, but also cover energy standards, electrical and plumbing installations, windows, doors and roof coverings.

The law is complex and Watford developers should always seek advice from qualified tradespeople, consultants or the local authority planning and building control departments.
