The landlord who is seeking possession or, if that landlord is a registered housing association or charitable housing trust, a superior landlord intends to demolish or reconstruct the whole or a substantial part of the dwelling-house or to carry out substantial works on the dwelling-house or any part thereof or any building of which it forms part and the following conditions are fulfilled—
the intended work cannot reasonably be carried out without the tenant giving up possession of the dwelling-house because—
the tenant is not willing to agree to such a variation of the terms of the tenancy as would give such access and other facilities as would permit the intended work to be carried out, or
the nature of the intended work is such that no such variation is practicable, or
the tenant is not willing to accept an assured tenancy of such part only of the dwelling-house (in this sub-paragraph referred to as “the reduced part”) as would leave in the possession of his landlord so much of the dwelling-house as would be reasonable to enable the intended work to be carried out and, where appropriate, as would give such access and other facilities over the reduced part as would permit the intended work to be carried out, or
the nature of the intended work is such that such a tenancy is not practicable; and
either the landlord seeking possession acquired his interest in the dwelling-house before the grant of the tenancy or that interest was in existence at the time of that grant and neither that landlord (or, in the case of joint landlords, any of them) nor any other person who, alone or jointly with others, has acquired that interest since that time acquired it for money or money’s worth; and
the assured tenancy on which the dwelling-house is let did not come into being by virtue of any provision of Schedule 1 to the [1977 c. 42.] Rent Act 1977, as amended by Part I of Schedule 4 to this Act or, as the case may be, section 4 of the [1976 c. 80.] Rent (Agriculture) Act 1976, as amended by Part II of that Schedule.
For the purposes of this ground, if, immediately before the grant of the tenancy, the tenant to whom it was granted or, if it was granted to joint tenants, any of them was the tenant or one of the joint tenants under an earlier assured tenancy of the dwelling-house concerned, any reference in paragraph (b) above to the grant of the tenancy is a reference to the grant of that earlier assured tenancy.
For the purposes of this ground “registered housing association” has the same meaning as in the [1985 c. 69.] Housing Associations Act 1985 and “charitable housing trust” means a housing trust, within the meaning of that Act, which is a charity, within the meaning of the [1960 c. 58.] Charities Act 1960.
