Private house, Hutton Grove, London N12

The house had been purchased without building approval for the existing open plan on the ground floor and an open staircase communicating with a loft extension accommodating two bedrooms – this contravened the guidance given under the building regulations. The problem was overcome with the provision of guidance and the installation of an automatic domestic sprinkler system according to BS DD 251 and an automatic fire detection system according to BS 5839 Part 6. This was accepted by building control.
