Full wordpress page (White Widgets and Widget Column)

I need to create a page within word press that uses the full width of the page, i.e. for that page only it removes the column that’s configured within my theme and the widgets I’m using (my theme uses a single column on the right side of the page). There is a plug-in called embededbbpress (was made to embede bbpress but I’m trying to embed something else) that lets me use the whole page however you have to manually set the height and width. The width isn’t that much of an issue but the height is as it doesn’t automatically grow with the content within the page. I also had to use another plugin called ‘Display widgets’ to hide my widgets from this page.
Does anyone know a way, without editing my theme, something like a plugin where I can create a page and it uses the full width of the page hiding the Column/widgets for that page only but also automatically adjust the height depending on the content? I have search the plug-in dir but couldn’t find anything that looked like it would suit my purpose. f.y.i the code I’m embedding in my page is vanilla forum emebded code, hence when I click on my page that I created within word press I want it to display in full width my forum and then automatically adjust the height.
thanks
