3 Duty to build dwellings properly
1 A person taking on work for or in connection with the provision of a dwelling (whether the dwelling is provided by the erection or by the conversion or enlargement of a building) owes a duty—
(a) if the dwelling is provided to the order of any person, to that person; and
(b) without prejudice to sub-paragraph ( a), to every person who acquires an estate in the dwelling;
to see that the work which he takes on is done in a workmanlike or, as the case may be, professional manner, with proper materials and so that as regards that work the dwelling will be fit for habitation when completed.
2 A person who takes on any such work for another on terms that he is to do it in accordance with instructions given by or on behalf of that other shall, to the extent to which he does it properly in accordance with those instructions, be treated for the purposes of this Article as discharging the duty imposed on him by paragraph (1) except where he owes a duty to the other to warn him of any defects in the instructions and fails to discharge that duty.
3 A person shall not be treated for the purposes of paragraph (2) as having given instructions for the doing of work merely because he has agreed to the work being done in a specified manner, with specified materials or to a specified design.
4 A person who—
(a) in the course of a business which consists of or includes providing or arranging for the provision of dwellings or installations in dwellings; or
(b) in the exercise of a power of making such provision or arrangements conferred by or by virtue of any statutory provision;
arranges for another to take on work for or in connection with the provision of a dwelling shall be treated for the purposes of this Article as included among the persons who have taken on the work.
5 Any cause of action in respect of a breach of the duty imposed by this Article shall be deemed, for the purposes of the Limitation (Northern Ireland) Order 1989 to have accrued at the time when the dwelling was completed, but if after that time a person who has done work for or in connection with the provison of the dwelling does further work to rectify the work he has already done, any such cause of action in respect of that further work shall be deemed for those purposes to have accrued at the time when the further work was finished.

4 Cases excluded from remedy under Article 3
1 Where—
(a) in connection with the provision of a dwelling or its first sale or letting for habitation any rights in respect of defects in the state of the dwelling are conferred by an approved scheme to which this Article applies on a person having or acquiring an estate in the dwelling; and
(b) it is stated in a document of a type approved for the purposes of this Article that the requirements as to design or construction imposed by or under the scheme have, or appear to have, been substantially complied with in relation to the dwelling;
no action shall be brought by any person having or acquiring an estate in the dwelling for breach of the duty imposed by Article 3 in relation to the dwelling.
2 A scheme to which this Article applies—
(a) may consist of any number of documents and any number of agreements or other transactions between any number of persons; but

3 In this Article “approved” means approved by the Department, and the power of the Department to approve a scheme or document for the purposes of this Article shall be exercisable by order, except that any requirements as to construction or design imposed under a scheme to which this Article applies may be approved without making any order or, if the Department thinks fit, by order.

(b) if any work for or in connection with the provision of the dwelling was done otherwise than in the course of a business by the person in occupation of the dwelling at the time of the compulsory acquisition, the acquiring authority and not that person shall be treated as the person who took on the work and accordingly as owing that duty.

5 Duty of care with respect to work done on premises not abated by disposal of premises
1 Where work of construction, repair, maintenance or demolition or any other work is done on or in relation to premises, any duty of care owed, because of the doing of the work, to persons who might reasonably be expected to be affected by defects in the state of the premises created by the doing of the work shall not be abated by the subsequent disposal of the premises by the person who owed the duty.
