Why it was refused

  1. The existing development does not constitute Lawful Development under Section 191 of Town and Country Planning Act 1990, Section 191 as amended by Section 10 of the Planning and Compensation Act 1991 as the applicant has failed to demonstrate, on the balance of probability, that the property has been used continuously as two separate self-contained residential units for a period of at least 10 years prior to the date of the application. The evidence submitted is insufficient, imprecise and does not satisfactorily establish the existence of two independent C3 dwellinghouses throughout the relevant period. Accordingly, the Local Planning Authority is not satisfied that the use is lawful within the meaning of Section 191 of the Town and Country Planning Act 1990. This determination is based on your submitted plans. All measurements are taken from existing ground level.

From the council's decision notice.
