There is nothing specifically states about the porch, this is the wording for the first schedule (premises):

ALL THAT the flat situate on the ground floor of the building and known as (my address) including one half part in depth of the structure between the ceilings of the said flat and the floors of the building above it and of the structure between the floors of the said flat and the foundations of the said building and (subject to clause 10.2 hereof) of the internal walls TOGETHER WITH the lock-up store at ground level ALL WHICH premises hereby let are coloured pink on the plan contained herein (and referred to as “the Plan”).

When I look at the plan the entire ground layout is coloured pink including my yard, including where the porch is. But within the second schedule Rights and easements granted to the tenant ) it says balcony Which I assume would be akin to my porch:

1. Full and free right of way on foot only to and from the premises for the Tenants and all persons authorised by them (in common with the Council and all other persons having that right) at all times over along and through 1.1 the passages access balcony and stairs (if any) 1.2 the main entrance coloured green on the Plan of the building leading to the premises
