Permission to construct additional structures.

    Where the landlord proposes to make any improvement in, or construct any additional structure on, any building which has been let to a tenant and the tenant refuses to allow the landlord to make such improvement or construct such additional structure, the landlord may apply to the court and the court may, if it is satisfied that the landlord is ready and willing to commence the work and that such work will not cause any undue hardship to the tenant, permit the landlord to do such work and may make such other orders as it thinks fit in the circumstances of the case.
