Yes, You Can Build Your Backyard in Phases Underground Goes First

Yes, phasing works well as long as drainage, grading, and underground work go in first. Lines for a future kitchen or fire feature can be stubbed in at that stage, so later phases don't mean tearing anything out.

This page covers the build sequence, what to rough in now for later features, and how phasing compares with one full build. Bring the Phase Planning Worksheet to your free 15-minute phone consult.

Why It Works This Way

The Order Matters More Than the Timing

Every outdoor project follows the same sequence, and phasing works when each phase respects it.

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.

Rough-Ins and Cost Factors

What to Plan For Before Phase One

01

Gas for a future kitchen or fire feature

If a grill, fire pit, or fireplace is on the wish list, the gas line can be run and capped during the underground phase. Altavera coordinates the gas work with licensed trades where required, so the later phase connects to a stub rather than cutting through a finished patio.

  • Gas
  • Fire feature
  • Kitchen

02

Electrical conduit

Lighting, outlets, a refrigerator, or a heater under the cover all need power. Running conduit to planned locations now keeps later trenching off your new hardscape, and it gives the electrical work a clean path when the kitchen or cover goes in.

  • Electrical
  • Lighting

03

Water lines and irrigation sleeves

A kitchen sink needs water and a drain path, and future planting beds need irrigation. Sleeves laid under pavers or concrete let lines pass through later without demolition. In canal and pressurized irrigation districts, we plan around how your system is fed and when it is charged.

  • Irrigation
  • Water

04

Remobilization

Every phase means bringing crews and equipment back to your property and setting up again. That return trip is a real cost factor, so fewer, well-planned phases usually price more efficiently than many small ones. Your estimator can show you where splitting the work makes sense.

  • Cost factor

05

Protecting finished areas

When equipment has to cross a finished patio or lawn to reach a later phase, those areas need protection, and sometimes repair. Access routes, gate widths, and where materials get staged all affect cost, so we plan each phase so later work does not damage earlier work.

  • Cost factor
  • Access

06

Sizing utilities for the full plan

Sizing gas, electrical, and water for the whole plan in phase one adds to the first phase. It usually avoids the larger cost of digging up and replacing lines later. See what drives outdoor project cost for the full list of factors.

Honest Comparison

Phasing vs. One Full Build

Both paths can end in the same backyard, and the difference is how work, cost, and disruption are spread out. If financing would let you build everything at once, see how financing works.

Who This Is For

Which Option Fits You

Phasing fits you if...

You want the foundation done right now and features like a kitchen, fire pit, or turf added as priorities allow. It also fits new-build lots where drainage and grading need attention before anything else, and families who want to live with the space before committing to the final layout.

One full build fits you if...

You know what you want, you would rather have one construction period, and you want to avoid the added cost of returning crews. It fits well when the scope is clear and financing or savings make a single project practical.

Our Process

How to Plan a Phased Project With Altavera

  1. Step 1: Write down the full wish list

    Start with everything you might want eventually, even if it is several phases away: covered patio, kitchen, fire feature, turf, lighting. The Phase Planning Worksheet below helps you sort it into now, next, and someday.

  2. Step 2: Book a free phone consult

    Use the phone consult calendar to book a free 15-minute call. Your estimator confirms the project is a fit and asks which pieces matter most to you first.

  3. Step 3: Walk the site with your estimator

    At the on-site estimate, we look at drainage, grading, soil (including caliche and clay), access, and where utilities would run for every phase, not just the first one.

  4. Step 4: Review a phased written proposal

    Your written proposal lays out phase one in detail and identifies the rough-ins that support later phases, so you can see what you are paying for now and why it is there.

  5. Step 5: Schedule phase one with a deposit

    A deposit puts phase one on the schedule. Spring and summer book up fast, so planning early helps. When you are ready for the next phase, it builds on what is already in the ground.

Phase Planning Worksheet Now, Next, Someday

Print it or keep it on your phone and bring it to your consult. It helps your estimator see the whole plan, not just the first phase.

First Phase: Foundation and First Build

  • Note areas where water pools or drains toward the house
  • Note slopes, low spots, or soft ground
  • List the hardscape you want built first
  • Mark where the covered patio or main seating area goes
  • Note where your irrigation connects and how it is fed
  • Ask which rough-ins belong in this phase

Later Phase: Planned Additions

  • List features planned next: kitchen, fire feature, turf, lighting
  • Mark where a grill, sink, or fire pit would sit
  • Note power needs: outlets, lighting, heaters, refrigerator
  • Ask what gas, electrical, and water stubs these need
  • Note how crews and equipment will reach this area later

Future Wish List

  • List ideas you are not sure about yet
  • Note HOA rules that might affect later features
  • Note changes ahead, such as kids, pets, or a future pool
  • Ask what to rough in now just in case

Your estimator uses this to plan the sequence and rough-ins, and the written proposal confirms what each phase includes.

FAQ

Phasing Outdoor Projects FAQs

Can we do part of the project now and finish the rest in spring?

Yes. Phasing works well as long as drainage, grading, and underground work go in first. Lines for a future kitchen or fire feature can be stubbed in during that first phase, so later work connects to them instead of tearing out finished pavers. Your estimator reviews timing once the scope is defined, and spring and summer book up fast, so it helps to plan the next phase early.

Can I build a covered patio now and add an outdoor kitchen or fire pit later?

Yes, and it is a common way to phase. Gas, electrical and water are run and capped where the kitchen or fire feature will go before the patio is built, all coordinated under one contract with licensed trades where required, so the later phase ties into those stubs. Homeowners in Caldwell, Nampa, and across the Treasure Valley use this approach to spread out a larger plan.

What has to go in first when phasing a backyard?

Drainage and grading always come first, followed by underground work like irrigation and utilities. Hardscape and structures come next, and landscaping and finish come last. Building out of that order is what usually forces tear-out, because pipe and conduit cannot be added under a finished patio without removing it.

Does phasing cost more than doing everything at once?

It can. Each phase means crews and equipment return to your property, and finished areas may need protection while later work happens. Careful planning keeps those added costs down, especially when the rough-ins for later phases go in during the first phase. Your estimator can explain how phasing affects your specific project.

Will each phase need its own permit or HOA approval?

It depends on what each phase includes. Altavera pulls the permit when a project needs one and coordinates HOA review. In Meridian, Eagle, and other communities with architectural review, it often helps to share the full plan early so the HOA understands where later phases are headed.

Do I need to know my whole plan before starting phase one?

It helps, but you don't need every detail. We need enough of the big picture to size utilities, place stubs, and set grades that work for future features. Bring your wish list to the free 15-minute phone consult, and design ideas get worked out as part of the estimate process.
