How To Build a Custom Home

By Atera Homes · May 31, 2026 · 6–8 minute read

Building a custom home means shaping every part of your house around how you actually live—from where it sits on the land to how the floor plan, finishes, and systems come together. It is a bigger commitment than buying a spec home, but it also offers a level of control and fit that is hard to match. [web:404][web:411]

Atera Homes focuses on making that process feel manageable and enjoyable, guiding you from early ideas and budgeting all the way through design and construction. [web:404]

Steps to building a custom home

Atera describes the custom home process as an experience because the goal is not just a finished house—it is a journey where you feel heard, informed, and supported at every step. [web:404][web:381]

While every project is unique, most follow a version of the steps below. [web:404]

1. Consultation

The process begins with a conversation about your goals, preferred locations, budget, and how you want to live day to day. Some clients arrive with detailed ideas and inspiration; others lean more heavily on the design team to help shape the vision. [web:404][web:409]

During this stage, Atera walks you through services such as budgeting support, permitting, land search, planning, and construction management, and can coordinate with your realtor and lender so everyone is aligned early. [web:404]

If you do not already have an agent, the team often collaborates with trusted partners—such as realtor Deanna Barley—who understand both real estate and design considerations for custom builds. [web:404]

2. Finding land

Securing the right lot is one of the most important—and sometimes most challenging—parts of building a custom home. Lot size, slope, views, privacy, and access all influence what is possible. [web:404][web:396]

Atera helps you evaluate candidate properties, looking at how they might support features such as pools, guest suites, or additional structures, and can point you toward neighborhoods that align with your priorities. [web:404]

3. Planning

Land planning is where your wish list starts to become a tangible layout, looking at how spaces relate, how you move through the home, and which rooms or amenities matter most. [web:404]

Clients often consider features such as game or play rooms, libraries, art or hobby spaces, elevators, large kitchens, bedroom counts, room sizes, circulation, and balconies, starting from scratch or adapting existing Atera plans. [web:404][web:373]

4. Designing

With the overall plan in place, attention shifts to interior and exterior design. Atera’s in‑house design team works closely with you to understand your style, how formal or informal you want spaces to feel, and how interior and exterior should connect. [web:404][web:411]

This includes decisions about flooring, tile, carpet, ceilings, colors, roofing, exterior materials, windows, and more—along with the “must‑have” features you want your home to include. [web:404][web:411]

5. 3D architectural design

To help you visualize the design before anything is built, Atera uses architectural design tools and 3D visualization, making it easier to refine spaces, materials, and colors with confidence. [web:404][web:411]

Adjustments at this stage are far easier and less costly than changes during construction, so time invested here tends to pay off later. [web:404]

6. Financing

Custom construction financing differs from a standard mortgage; lenders such as WaFd Bank offer single‑close construction‑to‑permanent loans that simplify fees and rate management. [web:404]

Documentation such as plans, itemized costs, and specifications is prepared so lenders can evaluate the project, and they also help coordinate requirements like permits and contractor information prior to closing. [web:404]

7. Building

Once permits, financing, and selections are in place, construction begins. Atera oversees the build from site work through framing, systems, finishes, and final details, keeping you as involved as you would like. [web:404]

Because planning and design happen up front, materials and details are ready before construction starts; for many projects, the on‑site building phase runs roughly 10–14 months, depending on size and complexity. [web:404]

Where Atera builds custom homes

Atera builds custom homes across much of the greater Seattle and Eastside area, including Bellevue, Renton, Kirkland, Seattle, Issaquah, Newcastle, Redmond, and Mercer Island. [web:404][web:397]

For clients outside these areas, Atera can provide planning and design services to develop a complete package of drawings, specifications, and cost information to share with your lender and local builder. [web:404]

In addition to new builds, the team periodically has completed homes available for purchase in the greater Seattle area. [web:398]

How much does it cost to build a custom home?

There is no single price‑per‑square‑foot that fits every custom home; total cost depends on home size, structural complexity, level of finish, site conditions, and the features you prioritize. [web:404]

Atera provides detailed estimates before construction so you can coordinate with your realtor and lender, refine scope where needed, and move forward with clarity about the budget. [web:404]

How long does it take to build a custom home?

Because Atera handles planning, design, and construction under one roof, the overall process can be more streamlined than coordinating multiple separate firms. Once construction begins, many projects complete in approximately 10–14 months, shaped by design decisions and permit timing. [web:404]

Having decisions made early and materials lined up before site work starts helps minimize delays and keeps the build moving steadily from foundation to move‑in. [web:404]

Living the Atera life

For Atera, “the Atera life” means living in a home that feels like a sanctuary, tailored to your routines and sense of style, and feeling excited and involved throughout the process as well as at home in the finished result for years to come. [web:404][web:409]

If you are starting to consider a custom home in Washington and want an all‑in‑one team to guide you, Atera is available to discuss new builds, available homes, or early planning for a future project. [web:404]
