You can head over to YouTube to find a bunch of different base designs depending on what you want your base too look like. In your case, you would look for a clan war/trophy base design. I've learned how to design my base by watching a couple videos there. You can learn from them or simply copy their layouts. And its fun to watch and easy to learn from videos.
Also, try not to pick a common base layout because a lot of people know how to attack them now or if you use it in clan wars, someone can search it up on youtube and see all of your traps.
