Duplex Properties

The word duplex can be referred to in several ways and the circumstances for each one are shown below:

It can refer to a specific structure type e.g. Duplex Foamed Slag.

Where there are two leasehold properties each covering two storeys in a block of four storeys. These types of property are maisonettes. However, in some developments they are referred to as duplex houses/maisonettes.

These buildings are also known in their locality by the name of "Over and Under" type properties. They were built up to four or five storeys high in steep hillside terrace form, arranged similar to maisonettes, with each property having ground level access. Some involved back to back arrangements. Construction is normally of stone and quality of construction varies from poor to very good.

Essentially these properties are flying freeholds, and normally would not form an acceptable security for the Society. However, the Society will accept these Duplex properties provided the following procedures are strictly adhered to:

  1. Prior to valuation, the conveyancer must confirm the property is in an area covered by the West Yorkshire Act 1980.
  2. The valuer has strict criteria to judge the acceptability of Duplex properties.
