“All those premises demised by and included in the Superior Lease other than the 25 Flats… and without prejudice to the generality of the foregoing specifically includes … the main walls structure and roof of the property including all walls not included in any flat or dividing any flat from another.”
“Given that there was an absolute prohibition against any “external additions”, the erection of these conservatories would have been unlawful. Mr Maltz argues that when the [respondent] acquired her lease, she would not reasonably expect to be required to contribute to the landlord’s costs of repairing and maintaining these unauthorised structures.”
“…. it would not have been the intention of the original parties to these sub-leases that the sub-lessees of flats 1-24 would be required to contribute, through the service charge, to the cost of repairing and maintaining an unlawful addition erected whether by the sub- lessee or, indeed, the intermediate landlord of the penthouse.”
“When interpreting a written contract, the court is concerned to identify the intention of the parties by reference to "what a reasonable person having all the background knowledge which would have been available to the parties would have understood them to be using the language in the contract to mean", to quote Lord Hoffmann in Chartbrook Ltd v Persimmon Homes Ltd[2009] UKHL 38 ,[2009] 1 AC 1101 , para 14. And it does so by focussing on the meaning of the relevant words, in this case clause 3(2) of each of the 25 leases, in their documentary, factual and commercial context. That meaning has to be assessed in the light of (i) the natural and ordinary meaning of the clause, (ii) any other relevant provisions of the lease, (iii) the overall purpose of the clause and the lease, (iv) the facts and circumstances known or assumed by the parties at the time that the document was executed, and (v) commercial common sense, but (vi) disregarding subjective evidence of any party's intentions.”
“… in some cases, an event subsequently occurs which was plainly not intended or contemplated by the parties, judging from the language of their contract. In such a case, if it is clear what the parties would have intended, the court will give effect to that intention.”
“If a lessee whose lease contains such a [repairing] covenant erects a house on the land leased to him he is just as much bound to maintain it and keep it in repair as if it had been built before the lease was granted.”
