The specific characteristics of the premises may be affected by extrinsic elements consisting of accessory premises, ancillary premises or outbuildings, let by the same lessor and likely to be used in conjunction with the main premises.
Where the rented premises include a residential part, the rental value of this part is determined by comparison with the prices charged for similar residential premises that are the subject of a new lease, increased or decreased to take account of the advantages or disadvantages presented by their integration into a commercial whole.
