Tooting Lodge (98-100 Tooting Bec Road) is a grade II listed building that has been unused for a number of years. Renovation works have been slowly made to the Lodge over the last few years and it is looking a lot better now than it was. The owner has made a number of planning applications that local residents may wish to comment on:
Planning application 2018/5710: temporary change of use of Lodge and part of the site from Nursery (Class D1) to 1 x 2-bedroom residential unit (Class C3) and alterations including inclusion of additional doors at ground floor level.
These two applications are for the same thing, one is the listed building consent 2018/6129 and the other is the planning permission 2018/6118: demolition of single storey extension and outbuildings and erection of replacement single storey extension, single storey building for use as gym (Class D2) with link corridor to the Lodge and single storey building for use as car show room (Class A1) including associated office, show room and covered display area in open yard area.

If you want to comment on these plans (in support, to object, or just to make a neutral comment), please click on the links above to the planning applications and click on “View Associated Application Documents & Make Online Comments for Live Applications” then click on “Comment On Application”. The form for making comments is very straightforward.
Personally, we do not think the planned new building looks particularly in keeping with the Lodge, and we do not think the area needs a car showroom. But your views may differ, and everyone is entitled to make their own comments on the proposals.
