PDR - Loft Conversions

Loft conversions are often the best way of maximising your space if you do not have the room to extend to the front or rear of your home. A typical Victorian terraced house has enough room to add at least one additional bedroom and bathroom. Loft rooms often command excellent views, maximise natural light, and can add value to your home.

Permitted Development Rights allow most homes to build into the loft space and achieve far more than would be possible through planning. For example, under Permitted Development you can add much more glazing than you would be allowed with planning permission. Chances are your loft conversion would also be significantly larger under Permitted Development than you could achieve through planning permission

The above details are a guide only and are not exhaustive. Every property is unique and your home could have restrictions on it’s permitted development rights. Holland and Green recommend all of our clients obtain a Certificate of Lawful Development before undertaking any building work. A Certificate of Lawful Development is a legally binding document from your Local Council confirming that the work you are undertaking falls within permitted development allowances.
