Altavera builds in one order: drainage and grading, then underground (irrigation and utilities), then hardscape and structures, then landscaping and finish. Water has to move away from your house before anything goes on top of it, and pipe, conduit, and gas lines have to sit below the patio before the patio is poured or laid. When a phase skips ahead, the next phase usually starts by removing finished work.
That is why a sensible first phase is often the least visible one. On a Boise backyard renovation, phase one might be grading, drainage, sleeves under the future patio, and stubbed gas and electrical. Then the covered patio or paver patio goes in on a base that is ready for what comes next.
Later phases then connect to what is already waiting in the ground. A Meridian outdoor kitchen or fire feature ties into lines stubbed during phase one instead of trenching through new pavers. Your estimator reviews timing once the scope is defined, and the written proposal can lay out each phase separately so you can see what is included now and what is planned for later.
Key Takeaway
Phase by layer, not by corner of the yard. Get drainage, grading, and underground right first, and every later phase builds on it instead of tearing into it.
