Key legal question
Whether the cedar cladding triggered a 25,000 CHF price increase or a 25,000 CHF deduction
Extracted holding
The parties agreed to cancel the 25,000 CHF extra for cedar because the delivered tint did not match the owner's choice; no basis existed for a second 25,000 CHF deduction from the forfait price.
Extracted reasoning
The contract annex indicated sapwood cladding with a 25,000 CHF extra for cedar. The later settlement only waived the extra value; it did not create a reduction of the forfait price.
