Two of the most common fears associated with starting a new home project are unexpected delays and unforeseen budget overruns. When these happen, they can be stressful both emotionally and financially.

What are the construction costs that most overlook? In this article, we discuss everything a future homeowner should know about the costs that may arise, sometimes unwanted, during execution, and why prefab homes, modular homes, and tiny homes can solve some of these problems.

1. Utilities

A plot further from the electricity or gas line, or the water and sewage network, will involve higher connection costs. It is essential to consider if other properties or lands are intervening, which, in some cases, may mean obtaining a crossing agreement from the respective owners. Difficult access to the lot could create logistical problems for the future construction site supply or, in the case of installing prefab house or modular building elements, difficult access for the necessary machinery to unload the components.

1. Terrain

A plot with a difference in level will always lead to additional expenses for the foundation execution. But additional is one thing, and unpredictable is even less desired. What could be unpredictable regarding the foundation? The soil itself, possible underground springs or infiltrations that are only discovered when the excavator starts digging for the foundation. In principle, the geotechnical study can reveal potential issues.

1. Construction Materials

Another problem that may arise during the process, especially in the case of self-managed projects or with multiple contractors, is the increase in the price of construction materials. A price increase, however small, can ultimately have a domino effect, requiring serious additional expenses. Additionally, consider the possibility of not finding the desired materials or long waiting periods for them.

A wrong calculation of quantities can also change the budget during the works, a problem many traditional constructions still face.

1. Finishing

One of the most sensitive subjects is the finishing. The house's interface, perceived quality, and comfort level are provided by the finishes. From flooring to paint, from bathroom marble to yard paving, all these need to be carefully considered. A wrong calculation can result in new delivery expenses, especially if purchased from abroad. Measuring surfaces and considering allowances (for flooring, marble, carpet, etc.) saves you from later budget additions and work delays.

1. Landscaping

Upon completing the construction site, the yard itself is a small worksite. Expenses for leveling the land, planting ornamental trees or turf, paving, and decoration are, in most cases, forgotten or underestimated. When moving into the new home, it may just be a new house on an unarranged plot, degrading at the first rain. For example, paving involves quite large costs per square meter, reaching approximately 100 RON / square meter with materials and labor.

1. Common Mistakes

In addition to all the categories presented above that can directly impact your budget, errors often occur due to calculation, execution, or external factors such as weather, which can damage some materials.

In the case of Passivhaus BIOBUILDS homes, standardized prefab homes, modular homes, and tiny homes production allows us to eliminate many factors that may unexpectedly arise during the works.

Producing passive houses indoors certainly reduces costs and delays associated with rain, snow, or excessive heat, and automation reduces waste and execution errors. Almost every aspect of the design, engineering, production, installation, and finishing of your new passive house, eco-houses, or energy-efficient home is carried out by a single team coordinated by a dedicated project manager. Therefore, before starting the construction site, you will know exactly how much each element included in your passive house, eco modular house, or minimalistic small house costs and when you can move in.

Permits and Legal Fees

Obtaining the necessary permits and dealing with legal fees can be an overlooked aspect of building a new home. Zoning, building permits, and possible environmental regulations might all impact your budget. Consulting with a legal professional or a local authority to understand the requirements, fees, and potential challenges can save you from surprises down the line.

Off-the-Grid Preparation

For those looking to build off-the-grid-ready homes, additional costs may arise from installing alternative energy sources such as solar panels, wind turbines, or geothermal systems. These investments can save money in the long run but require a larger initial budget. Additionally, installing water collection and filtration systems, as well as waste disposal solutions, can add to the overall cost of the project.

Energy Efficiency and Green Building Features

Incorporating energy-efficient and green building features, such as advanced insulation, high-quality windows, and energy-efficient appliances, can also increase the initial costs of your project. However, these investments can result in long-term savings on utility bills and contribute to a more sustainable lifestyle.

Future-Proofing and Adaptability

As you build your new home, consider future-proofing and adaptability to accommodate changing needs or technologies. This might involve pre-wiring for electric vehicle charging stations, smart home technologies, or designing rooms with flexible uses. While these features might add to the initial budget, they can increase your home's value and appeal in the long run.

By being aware of these potential unexpected expenses and planning accordingly, you can minimize surprises and stay within your budget. Prefab homes, modular homes, and tiny homes can help mitigate some of these issues by offering cost-effective, energy-efficient, and eco-friendly options for future homeowners.
