Just think of the URL or page where you want your wordpress to appear, install(WP) there. If you keep both in home dir, then redirect index.php of wp through htaccess. Every kind of design can be done in wordpress if you have proficiency in the same. My suggestion is that keep one (either wp or code) and if you keep code in home dir, keep wp in some sub dir. The best option is do the whole thing in wp which good for SEO.
