“Premises to which Chapter applies (1) This Chapter applies to premises if − (a) they consist of a self-contained building or part of a building, with or without appurtenant property, (b) they contain two or more flats held by qualifying tenants, and (c) the total number of flats held by such tenants is not less than two-thirds of the total number of flats contained in the premises. (2) A building is a self-contained building if it is structurally detached. (3) A part of a building is a self-contained part of the building if − (a) it constitutes a vertical division of the building, (b) the structure of the building is such that it could be redeveloped independently of the rest of the building, and (c) subsection (4) applies in relation to it. (4) This subsection applies in relation to a part of a building if the relevant services provided for occupiers of it − 2 (a) are provided independently of the relevant services provided for occupiers of the rest of the building, or (b) could be so provided without involving the carrying out of works likely to result in a significant interruption in the provision of any relevant services for occupiers of the rest of the building. (5) Relevant services are services provided by means of pipes, cables or other fixed installations. (6) Schedule 6 (premises excepted from this Chapter) has effect.”
“...It was at one end of a long 4 storey block of flats built about 1990, with two storey town houses interspersed at intervals along the block, also with parking spaces and service areas below. The block was brick built under tiled roof with stucco plaster applied to up to first floor level. There were clearly problems with the plaster, which had fallen off or been hacked off. Flats 1-16 had their own separate entrance to the internal common parts and the basement parking area, but the entrance to the parking area ran under the town house at Number 17. The roller shutter security door and the two nearest parking spaces were also under Number 17. The garage had 11 marked spaces for parking, and it appeared that all the spaces belonged to flats 1-16, with the exception of the visitors’ space. The Tribunal noted that all services were well visible and exposed in the basement and they all ran in ducting across the roof of the car park, particularly the electricity. The supply to Number 17 appeared to be separately metered.”
“(1) For purposes of this Part of this Act, ‘house’ includes any building designed or adapted for living in...and (a) where a building is divided horizontally, the flats or other units into which it is so divided are not separate ‘houses’ though the building as a whole may be; and 4 (b) where a building is divided vertically the building as a whole is not a ‘house’ though any of the units into which it is divided may be. (2) References in this Part of this Act to a house do not apply to a house which is not structurally detached and of which a material part lies above or below a part of the structure not comprised in the house.”
