Web Application - Add On module approach

Hi,

I have two scenarios in my web application.

1) Add some fields in WebForms to the already existing and deployed WebApp.

2) Add totally new WebForms and its business, data access components in already existing and deployed WebApp.

Something Add-On module approach for the exsting web application.

How can I achieve this.

Please share your views or point to some resources.

Thanks
