Although there is indeed a new home construction systematic process the personal service nature of custom home building for clients, the actual procedure is rarely exactly the same.
The common factor of the custom home building process is that it consists of 3 primary stages, pre-construction, construction and post construction.
“Did You Know?
Custom home building timelines can vary by 30–50% depending solely on how well the pre-construction decisions are made — making early planning the most influential stage of the entire process.”
Key Takeaways
- The custom home process includes three primary stages: pre-construction, construction, and post-construction.
- A strong wish & needs list and a clear budget range help guide design accuracy.
- Home site selection influences cost, style, and layout restrictions.
- The construction phase relies on accurate documents, defined budgets, schedules, and ongoing communication.
- Post-construction is essential for compliance, warranty protection, and accurate documentation for future improvements.
The preconstruction stage is the design development phase, where imagination meets visual reality.
The second phase is the construction stage, where craftsmanship, materials and project management develop the virtual reality into expressed art form.
The post construction stage is the finalization of the construction process and document details.
What is the Pre-Construction Phase of Home Building Construction?

Develop Home Design Critical Factor
It is important that the owner develops a comprehensive wish & needs list for any major new home building construction project. This list must have the essential home design features such as total square footage, one or two stories and preferred architectural style. It should also identify number and types of rooms, ceiling heights and lifestyle use for living area spaces.
-
Target Investment Budget Range
At the preconstruction stage without construction documents the owner should have their investment range predetermined. This includes the total amount of the home site and improvements, architectural design and construction cost. Adding a contingency fee of 20% is a wise plan to allow for wish list sacrifices that owners are not willing to make.
-
Home Site Location
The building lot is also an essential element of the design stage. A house footprint is required to be positioned on the home site to comply with deed restriction covenants. These are restrictions on easements, building setback lines and architectural requirements. In addition, the lot cost can represent upwards as much as 50% of the total investment of a custom home in a highly desirable metro location like Houston, Texas.

Design for Lifestyle and Family

Special Architectural Design Features
The wants and needs list plays a large role in the architectural design process. No more important than when it is necessary to value engineer the home design because the cost is outside your investment comfort zone.

In some cases, its sufficient to change product brands to eliminate cost, while other times it may be necessary to redraw certain architectural features to meet your investment goals.
As a general rule, it is better to identify your special architectural features by priority. Design your home plans with priorities in mind and add the lesser architectural features after you are confident that your home design will fit your budget.

Finalize Your Home Materials & Products
Technically speaking selecting materials, products and colors is part of the preconstruction process. In many cases this task slides into the construction phase and the custom home builder will use unit cost prices for home product selections in the form of allowances, that are not made during home design stage.

Timely chooses will avoid such problems as late shipments, product unavailability, not allowing construction personnel time to create mock ups for customer verification of acceptance.

Construction Records

Progress Meetings
The communication with the owner during construction should be a high priority for the custom builder.

These meetings act as preventative assurance that details and misunderstandings are avoided.
-
Sample Approvals
Another effective onsite meeting agenda is to prepare material mock ups and place color samples in real time conditions for owner approval. Onsite sample displays give the owner a far better advantage of approving color shades and sheens in a perfect natural setting. They can judge them in an environment with natural light and the surrounding color influences.

Quality Control

Compliance Inspections
Third party compliance inspections are essential for assurance that construction meets the standards of building codes and specifications of the construction documents. Progress and final inspections provide these assurances.

Punch List Development

-
As-Builts & Manuals
An essential part of documenting new home construction improvements that are modified from the original plans for whatever reason, can be updated and correctly represented. As-builts play a significant role in diagnosing future problems or planning future improvements.
