Building a Custom House Requires Two Separate Contracts for "Land" and "Building"
Unlike built-for-sale homes or new condominiums, custom houses are built from scratch to reflect your own preferences. The key difference is that you must handle the "acquisition of land" and "building construction" separately.
When building a custom house in Sendai, you should generally expect the entire process from land search to delivery to take 1-2 years or more. It is important to manage both schedules and financial planning in parallel.
Step 1: Create a Financial Plan (1-2 months)
The first thing to do is clarify "how much you can spend." The total cost of a custom house consists of "land price + building cost + miscellaneous expenses."
Guidelines for Sendai
For housing loans, the common approach is to use "bridge financing" or "land-first financing" to borrow for both land and building together. Since financial institutions handle these differently, it is important to conduct a preliminary loan examination at an early stage to understand your borrowing capacity.
Step 2: Select a House Builder or Contractor (1-3 months)
In parallel with land search, you should select the construction company to build your home. There are many options including major house builders, local contractors, and architectural firms.
Key Selection Points
Narrowing down your construction company early makes it easier to assess whether "this company can build on this land in this area."
Step 3: Land Search (2-6 months)
Once your financial plan and builder concept are clear, begin the serious land search. Combining the following methods makes land searching in Sendai more efficient:

Step 4: Land Purchase Contract and Loan Procedures (1-2 months)
Once you have decided on the land to purchase, you will enter into a sales contract.
Process of Land Purchase
After land settlement, housing loan interest (bridge financing interest) accrues during the period between land acquisition and the start of building construction, making schedule management important for cost savings.
Step 5: Building Design, Application, and Construction Start (3-6 months)
After acquiring the land, the building design process becomes more serious.

Step 6: Construction Period (4-6 months)
For a typical wooden house, construction from start to completion takes generally 4-6 months. During construction, regularly inspect the site and notify your project manager of any issues as soon as they arise.

Step 7: Delivery and Move-In
After completion, inspections are conducted by the construction company and third-party inspection agencies. If no problems are found, the property is delivered to you. At delivery, final loan settlement, building registration, and ownership registration are also required.
After delivery, regular inspections are conducted as part of an "after-care period." Choosing a builder that conducts inspections at set intervals such as 1, 2, and 5 years after delivery provides peace of mind.
Common Failure Patterns and Countermeasures
Failure Example 1: Purchasing Land Hastily and Regetting It
Some people rush to purchase land they like without fully confirming ground condition, legal restrictions, and infrastructure status. Ground surveys can sometimes be conducted before the sales contract, so it is important to coordinate with your builder to conduct the survey early.
Failure Example 2: Building Cost Overrun
Land costs end up being higher than expected, leaving insufficient budget for the building. Set a budget allocation between land and building from the start, and actively negotiate on land price as a countermeasure.
Failure Example 3: Miscommunication with the Construction Company
Despite multiple consultations, some people feel "this is not what I expected" after completion. Use floor plans, specification sheets, and 3D renderings to carefully align the completed image with your builder.
Summary
The process of purchasing land and building a custom house in Sendai involves many steps—financial planning, land search, builder selection, design, and construction—and takes 1-2 years or more overall. Taking your time and proceeding methodically is the shortest path to realizing your ideal home.
Coordinating with real estate agencies and construction companies from the land selection stage makes smooth progress and budget management easier to achieve. Finding trustworthy partners is the most important key to success in building a custom house.
