Can an expropriated property be valued on a valuation based on immediate sale for use by the owner of the land for the purpose of building purposes?

In Horn v. Sunderland Corpn., supra, all of the claimant’s farm lands were expropriated. He was compensated on the basis of land ripe for urban development. The question to which the court directed its attention was whether the claimant could combine a valuation based on immediate sale for building purposes with a claim for disturbance and consequential damage on the footing of interference with argicultural operations. The answer of the majority of the court was that the claim for disturbance and consequential damage did not lie. The owner could only realize the building value in the market if he was willing to abandon his farming operations. Compensation would only be paid if the sum of the agricultural value and the claim for disturbance and consequential damage exceeded the building value.
