Planning permission refused :(

[hind]

hello all

I have had a planning permission refused in November by Southwark Council. My house is in the conservation area but not in the Dulwich Estate.

My concern is that the loft conversion I have requests has been approved for a house up my road ( further into the conservation).

Since then I have received two letters through the post from companies offering to appeal on my behalf.

Please help and advice on the following;

1- is it best to appeal directly of to hire the services of a company? Who woold you recommend?

2- any advise on how to approach this?

Many thanks

Hind
