Hey Aidan, congrats on your new home!
When it comes to renovation for landed homes, it's key to have a clear vision and communicate it clearly from the beginning of the project with your architect.
I worked closely with mine closely during our renovation previously in visiting multiple homes to get a vibe of how we would want our final product to look like.
Make sure your builder is on board with any unique elements, like the pool and porch you mention that you're planning to include. It's also helpful speak to multiple architects as from my experienced each have very different styles of working and design approach.
