Good Single page design example ..where you dont feel clutter but have lot of pages..!
Looking for SPA layout where many pages are present but its not cluttered..
Have gone through many dashboard layout where they have SPA..and looking for any other layouts..!
I'm having a hard time understanding the specific thing you're looking from. No worries though! I'd recommend looking through https://dribbble.com/ and https://www.behance.net/ for inspiration.
