“25. The debate on this application primarily revolved on analysis around the issue as to whether one must classify the insulated steel pipework as one "thing" or, in the context that the pipework was part of an installation in an overall building, whether it is to be considered simply as an indivisible part of the whole building. As in the Bellefield case, the claimant owner of the building was not owed by the builder a duty of care in respect of damage to the building. There is substantial authority, binding on this court, that a claimant cannot recover for the cost or loss of the negligently manufactured, designed or constructed "thing" itself. So, the purchaser of a ginger beer bottle which contains a snail may recover for personal injuries caused if she drinks the ginger beer but not for the cost of the bottle. 26. Considering cases such as Murphy, D&F Estates and Bellefield, they were primarily concerned with whether the overall builder of the whole building owes a duty of care to owners or occupiers of that building with whom it has not been in contract. It is well established law in such a case that the builder's duty of care, at least generally if not invariably, does not extend to damage to the building itself. Thus, any duty of care owed by a builder who carelessly constructs foundations which consequently leads to the building settling and cracking, does not extend to the damage to the building, let alone the foundations on which it is resting. If the building collapsed injuring a person or damaging his or her car or adjacent building, the builder's duty of care would extend to such person, such injury and such damage. It could thus be said that the "complex structure theory", to the extent that it has survived at all, does not operate to extend any duty of care by the builder to the owner or occupier, at least with regard to damage to the building itself.”
“I cannot see any way in which the reasoning in the paragraph quoted and the consequences in relation to the measure of damages can in principle be supported except by an extreme application of the complex structure theory treating each part of the entire structure as a separate item of property. But such an application of the theory seems to me quite unrealistic. The reality is that the structural elements in any building form a single indivisible unit of which the different parts are essentially interdependent. To the extent that there is any defect in one part of the structure it must to a greater or lesser degree necessarily affect all other parts of the structure. Therefore any defect in the structure is a defect in the quality of the whole and it is quite artificial, in order to impose a legal liability which the law would not otherwise impose, to treat a defect in an integral structure, so far as it weakens the structure, as a dangerous defect liable to cause damage to "other property." A critical distinction must be drawn here between some part of a complex structure which is said to be a "danger" only because it does not perform its proper function in sustaining the other parts and some distinct item incorporated in the structure which positively malfunctions so as to inflict positive damage on the structure in which it is incorporated. Thus, if a defective central heating boiler explodes and damages a house or a defective electrical installation malfunctions and sets the house on fire, I see no reason to doubt that the owner of the house, if he can prove that the damage was due to the negligence of the boiler manufacturer in the one case or the electrical contractor on the other, can recover damages in tort on Donoghue v. Stevenson [1932] A.C. 562 principles. But the position in law is entirely different where, by reason of the inadequacy of the foundations of the building to support the weight of the superstructure, differential settlement and consequent cracking occurs. Here, once the first cracks appear, the structure as a whole is seen to be defective and the nature of the defect is known. Even if, contrary to my view, the initial damage could be regarded as damage to other property caused by a latent defect, once thedefect is known the situation of the building owner is analogous to that of the car owner who discovers that the car has faulty brakes. He may have a house which, until repairs are effected, is unfit for habitation, but, subject to the reservation I have expressed with respect to ruinous buildings at or near the boundary of the owner's property, the building no longer represents a source of danger and as it deteriorates will only damage itself. For these reasons the complex structure theory offers no escape from the conclusion that damage to a house itself which is attributable to a defect in the structure of the house is not recoverable in tort on Donoghue v. Stevenson principles, but represents purely economic loss which is only recoverable in contract or in tort by reason of some special relationship of proximity which imposes on the tortfeasor a duty of care to protect against economic loss.”
“It was submitted that there was a liability to indemnify on the grounds that the other half of the cottages represented "other property" or work covered by the "complex structure" theory. The two cottages share a common foundation which serves both halves. The building was built as a single entity. In my judgement it would be artificial to regard the other half as "other property". That refers both to property that belongs to another property which is materially separate from the building in question. Hence in Bellefield the claimants were able to recover for damage to contents as they were "other property" but the Court of Appeal regarding dividing the building into parts based on differences in function as "a thoroughly undesirable approach" (see Schliemann L.J. at page 105 and see also Wall J. at page 106-[references are to[2000] BLR 97 ]). In my judgement it would not be consistent with the policy established by the House of Lords to try to find ways round it. The House of Lords has grappled with the policy considerations on at least four occasions (Anns, D&F, Murphy and DoE v Bates) and although there remain well founded reservations about the consequences of the permitting those who make culpable errors can escape liability to their neighbours (in law) for reasonably foreseeable loss and damage suffered by those who must have been in contemplation as likely to be affected by the errors, that is the law of this country.”
“In the light of these speeches not only is the "complex structure" exception no longer tenable but it is also clear that in approaching the question of "another part of the property" it is necessary to avoid any artificiality and to be realistic. To treat the part of the foundation slab under No. 1 as if it were separate from that part under No. 2 would be completely unrealistic…”
“(1) Subject to the following provisions of this section, where— (a) a cause of action (“the original cause of action”) has accrued to any person in respect of any negligence to which damage to any property in which he has an interest is attributable (in whole or in part), and (b) another person acquires an interest in that property after the date on which the original cause of action accrued but before the material facts about the damage have become known to any person who, at the time when he first has knowledge of those facts, has any interest in the property; a fresh cause of action in respect of that negligence shall accrue to that other person on the date on which he acquires his interest in the property. (2) A cause of action accruing to any person by virtue of subsection (1) above— (a) shall be treated as if based on breach of a duty of care at common law owed to the person to whom it accrues; and (b) shall be treated for the purposes of section 14A of the 1980 Act (special time limit for negligence actions where facts relevant to cause of action are not known at date of accrual) as having accrued on the date on which the original cause of action accrued… (4) Subsection (1) above shall not apply in any case where the person acquiring an interest in the damaged property is either— (a) a person in whom the original cause of action vests by operation of law; or (b) a person in whom the interest in that property vests by virtue of any order made by a court undersection 538 of the Companies Act 1985 (vesting of company property in liquidator). (5) For the purposes of subsection (1) (b) above, the material facts about the damage are such facts about the damage as would lead a reasonable person who has an interest in the damaged property at the time when those facts become known to him to consider it sufficiently serious to justify his instituting proceedings for damages against a defendant who did not dispute liability and was able to satisfy a judgment. (6) For the purposes of this section a person’s knowledge includes knowledge which he might reasonably have been expected to acquire— (a) from facts observable or ascertainable by him; or (b) from facts ascertainable by him with the help of appropriate expert advice which it is reasonable for him to seek; but a person shall not be taken by virtue of this subsection to have knowledge of a fact ascertainable by him only with the help of expert advice so long as he has taken all reasonable steps to obtain (and, where appropriate, to act on) that advice.”
“However, in the present case the whole of the dairy was built at the same time by the builders, marketed as a unit, bought as a unit to be used as a unit and was used as a unit. I have no doubt that any holding either that (1) the rooms on one side of the wall should be treated for present purposes as constituting a different building from the runs on the other side of the wall, or that (2) the wall should be treated as constituting a different building from the rooms on one side of it, would be a thoroughly undesirable approach to the issues before us." Of course, there is a distinction between the current case and the Bellefield case because in the current case the terrace units were designed and constructed as one building but marketed as separate units to be used and occupied by separate occupiers. Tuckey LJ adverted to the fact that there could be considered to be an anomaly in the law because the Claimant was able to recover damage to "other property, such as office equipment, general content and stock. However that did not alter his views about the policy involved and after referring to the well-known dissenting judgement of Lord Brandon in Junior Books v Veitchi[1983] AC 520 , he said, at Page 106: “It is these difficulties which I think justify the policy which prevents recovery in tort against the builder in this case the defects in the building which have caused damage to it…”
