Why it was refused

  1. Due its scale, design and location, the proposed extension to the annexe would result in an ancillary structure which is no longer subservient to the main dwelling and erodes the spatial qualities to the existing plot. The proposal would therefore neither preserve nor enhance the character and appearance of the Moor Park Conservation Area. It therefore would fail to accord with policies HC4 House Extensions, Houses in Multiple Occupations and Flats, EQ2 Design, NH9 Heritage Assets and NH12 Conservation Areas of the Local Plan for Sefton 2017.

From the council's decision notice.
