Appeal and objection are two different things in planning terms. You wish to object to the application and you can use whatever grounds you want, whether valid or not, within the designated timescale. However, only valid points of objection are likely to be considered grounds for refusal.
The other option is to gain a weight to the objection (i.e. lots of people objecting) and even to meet your local councillor and get him on-side (can be particularly handy if he sits on the planning committee).
However, if your attitutude is one of NIMBY'ism, then you don't stand much chance I'm afraid.
First thing I would do is go into your local council offices and see where you can look at a copy of the Local Plan covering your area. Have a look at the planning policy guidelines covering the site in question. If these are in accordance with the development proposals being applied for, then you will have to find more generic adopted policy that the proposals contravene.
Also, do some reasearch on Rights of Light. I think there's some fairly descript wording as to what constitutes this, but unless somethings being built withtin 9 meters of your house and very high, it's unlikely there will be any infringement.
I'm not a planning expert but do have some experience so let me know if I can be of anymore help.
