In 1835 Jennison was approached by businessman George Gill, who suggested that he lease Belle Vue – a public house in of open land between Kirkmanshulme Lane and Hyde Road – as a more suitable site for his aviary. Jennison took out a mortgage of £300 to pay off the £80 mortgage on the Strawberry Gardens and spent the remainder on a trial six-month lease of the Belle Vue property, in June 1836. In December Jennison signed a 99-year lease at a rent of £135 per annum. For an extra £100 a year he leased additional land to extend the western boundary to Redgate Lane, close to Stockport Road, where he made a second entrance. To finance further expansion Jennison re-mortgaged the site for £800.
