Entrust it to New-House! Since 1991, we have been offering comprehensive home construction services, which also include project realization and professional adaptation preparation.

Is Home Project Adaptation Worth It?

Individuals deciding to build a home face many challenging decisions. Some of them concern choosing the dream project. There are three options available: an individual home project from an architect, a ready-made building plan, or adapting a existing project. Each of these choices has its advantages and disadvantages. Today, we will discuss the last option in detail - adaptation.

How much does adapting a project to a site cost? How long does modifying a ready-made plan take? What does collaboration with an architect entail in this solution? These are just some of the many questions posed by investors interested in this type of service. We always strive to provide detailed and comprehensive answers to the questions we are asked. We are a construction company, and since 1991, we have been offering comprehensive home construction services - we have extensive experience and specialized knowledge. We gladly share this with our investors because, in line with our company's philosophy, we want our clients to make the most informed and thoughtful decisions. In today's article, we intend to answer all the questions that arise regarding building project adaptation.


What Does Adapting a Ready-Made Project Involve?

Adapting a project to a site and the client's individual needs is a great solution. It can be used in various situations, for example, when:

  • The building plot is non-standard and doesn't fit the project you've chosen,

  • You like a specific design, but you'd like it in a larger or smaller version,

  • You're interested in minor changes to a ready-made project, such as moving doors, windows, etc.

These are the main reasons that clients consider when opting for this type of collaboration. Adapting a ready-made project requires selecting and purchasing a pre-prepared, universal home design. The New-House website offers a complete database that has been richly equipped with ready home designs. Then, the chosen construction plan is handed over to an architect. Adapting a home project is a good solution because often - despite the sincere efforts of designers and a wide selection - it is difficult to precisely match a ready-made project to the investor's needs and the requirements of a specific plot. Furthermore, for those interested in the cost of project adaptation, it's important to note that the price of such collaboration is significantly lower than an individual home project. Despite the much lower price, the final design will be tailored to individual needs!

How Does the Home Project Adaptation Process Work?

As we mentioned before, after choosing and purchasing the project, it goes into the hands of an architect. From our side, as individuals with years of experience in the construction industry, we can advise that even before purchasing a project, you should contact an architect. Home project adaptation must meet the requirements of the local spatial development plan or building conditions set by the local authority. If the planned adaptation of the construction project doesn't comply with aspects like area ratio limits, roof pitch angle, or distance from neighbors, expect a refusal when applying for a building permit. By reaching out to a qualified architect beforehand, they can verify whether the planned adaptation of the building project meets specific requirements and can be carried out.

The next step will be defining your needs in a discussion with the architect. The designer performs the adaptation, and based on it, an application for a building permit can be submitted. Land development planning is also carried out during this process. The actual home project adaptation is done very quickly - usually taking about two to three weeks. It's worth emphasizing that collaboration on an individual project typically takes about three months on average. In this aspect, home project adaptation also comes out ahead.

The adaptation of a construction project can take two forms: basic and extensive. They differ in terms of the changes made.

  • Basic project adaptation – in this case, the architect needs to make minor changes to the project, such as moving a window, door, or partition wall. When a basic project adaptation is carried out, the cost is not high.

  • Extensive project adaptation – this collaboration requires a significantly greater effort from the architect and may even involve a structural engineer. It includes tasks such as increasing or decreasing the building's volume, changing load-bearing walls, or altering the garage's area. If an extensive adaptation of the construction project is being done, the cost will be much higher than in the case of the basic version.

How Much Does Project Adaptation for a Site Cost?

We understand that the financial aspect has a very significant influence on the final decision of investors. Moreover, this is often the most crucial deciding factor, so it's not surprising that the question of how much project adaptation for a site costs frequently arises among investors.

First and foremost, it depends on the extent of the changes to be made. A straightforward, uncomplicated adaptation of a construction project is inexpensive. Typically, the cost of collaboration with an architect does not exceed 700 Polish złoty in this case. The average price ranges from 500 to 700 Polish złoty for such a service. Of course, you also need to add the cost of the ready-made project, which usually amounts to a few thousand Polish złoty, around three or four. This is a very competitive price for a design tailored to individual needs.

However, if a larger adaptation of the construction project is carried out, the cost will be higher. This type of collaboration requires not only the architect's additional work but also that of a structural engineer who needs to recalculate the structure. Due to the greater effort involved, the cost of adapting a construction project usually ranges between three and four thousand. However, if you analyze how much adapting a ready-made project costs compared to the price of an individual project, it's easy to deduce that this is still a cost-effective decision. The total cost of project adaptation (including the cost of purchasing the ready-made plan) generally does not exceed seven thousand Polish złoty, whereas the cost of an individual project starts from twelve thousand.

What Does Adapting a Ready-Made Project Look Like?

Building a home must be carried out based on a professional design. An architect can create an individual home project, or you can choose one of the readily available solutions. There's also a third option that combines the benefits of individual and ready-made projects - that's adapting a construction project. What does this type of collaboration involve? Is it worthwhile?

Each of these options has its advantages. Individuals choose an individual home project when they want the construction to be perfectly tailored to their expectations and needs. On the other hand, ready-made projects are chosen by those looking for more budget-friendly options. How can you combine a low price with personalized construction? Adapting a ready-made project is the ideal solution.

What Is Involved in Adapting a Home Project?

Ready-made projects are increasingly popular among Polish investors. The construction market offers a growing number of them, allowing investors to tailor their choices to their preferences. You can find a database of such projects at this link: After choosing one, you will need to carry out the appropriate adaptation.

Adapting a ready-made project simply involves adjusting the chosen design to the conditions of the plot and the investor's individual expectations and needs.

What Should an Adapted Home Project Include?

This process can take various forms, depending on the requirements set for the architect. In the case of a simple adaptation, only elements such as the placement of windows and doors may change, and occasionally partition walls may be shifted. Adapting a ready-made project can also be a much larger undertaking, involving changes to the building's volume or the position of load-bearing walls. In such cases, a structural engineer must also be involved in the adaptation process. If a significant project adaptation is being carried out, the cost will be higher. It's also important to remember that the prepared project must comply with the local spatial development plan or building conditions.

Project Adaptation and Copyright

How does making changes to a purchased ready-made project relate to copyright law? Is it not a violation of respect for the architect's work and creativity? How can this be done legally? These are important questions, but every designer who carries out adaptations knows the answers.

It's true that every home project is protected by copyright law. However, each of these projects also has clearly defined elements that can be modified during construction without contacting the creator. The scope of possible changes depends on the architect themselves - sometimes they provide investors with a lot of flexibility, while other times the potential for changes is more limited. It's worth remembering that for most additional changes, you can obtain permission by contacting the relevant architect in advance. In most cases, such permission is granted free of charge.

How Does the Project Adaptation Process Work? Step by Step

The person responsible for project adaptation must first conduct a proper analysis – it is necessary to recognize the investor's expectations, familiarize oneself with the municipality's requirements, plot dimensions, and terrain quality. Only based on this information can work on preparing the appropriate plan begin. The actual project adaptation usually takes about three weeks, whereas preparing an individual construction plan takes about three months.

Adapting a ready-made project requires the creation of a site development plan. The architect must place the outline of the planned house on the map for design purposes. It's also necessary to indicate the layout of utilities, the location of connections, small architecture elements, etc. Changes are also made to the house project itself based on previous agreements. Applying for a building permit from the local authority is also necessary.

Adapting a Construction Project - What Documents Are Required?

When applying for a building permit, you must also prepare a series of other documents that will help determine whether the construction plan is properly executed. The following are required:

  • Decision on building conditions or an excerpt and plan from the local spatial development plan,

  • Excerpt and plan from the local land register,

  • Document confirming access to a public road,

  • Map for design purposes,

  • Conditions for connecting utilities (power, gas, water and sewage).

This is a list of the basic documents required when adapting a construction project. However, it's important to note that the list may be expanded with other certificates, depending on the type of construction and its location. For example, if you're building a house near a shoreline, you will need to provide the local authority with a project for delineating the water-covered lands from the adjacent lands, which will need to be done by a surveyor.

The waiting time for the building permit to be reviewed should not exceed 65 days.

Project Adaptation - Cost

For many people, the most attractive aspect of adaptation is its cost. It's probably the most financially advantageous solution. An individual home construction project is unlikely to cost less than 12,000 Polish złoty, but it will result in a plan perfectly tailored to your requirements. In the case of a ready-made project, the cost may be four or five times lower, but personalized solutions are missing. So, what exactly is behind the term "project adaptation cost"?

A simple, not very extensive project adaptation has a very reasonable cost. If you decide on such a solution, the cost should not exceed 800 złoty. Typically, it's around 500 - 700 złoty. The total investment amount must also include the cost of purchasing the ready-made project itself.

On the other hand, if you opt for a more extensive project adaptation, which requires more involvement, you should also prepare for a significantly higher cost. If you want to change the building's volume, move load-bearing walls, or alter other key aspects of the project, you should expect a cost of three to four thousand złoty, plus the cost of the ready-made project. While this is a significantly larger investment, it's important to consider that it's still a more cost-effective solution than an individual collaboration with an architect!

Can Project Adaptation Be Done Without the Author's Consent?

A project is a creative work and is therefore protected by copyright law. Nevertheless, certain changes can be made to it without obtaining permission from the designer. The exact scope of changes that can be included in project adaptation is always defined in the detailed documentation accompanying the chosen design. Usually, the scope of changes aims to allow the investor to adapt the construction to the possibilities of the site. Therefore, the completed adaptation should adjust the design to the conditions defined by the local spatial development plan or building regulations.

What Changes Can Project Adaptation Consider?

Changes to the project that can be made with the author's consent can cover a very wide range of work. Among them, you may find:

  • The issue of basement construction – not every project includes a basement, but it's almost always possible to add one. Similarly, you can omit it if it's not in the execution plan.

  • Materials used – if necessary, materials used for construction, insulation, and finishing can be changed. However, it's important that any changes adhere to required regulations and standards.

  • Type of floor slabs,

  • Shifting partition walls,

  • Moving windows and doors,

  • Building volume,

  • Building height,

  • Changing foundation dimensions – to match the soil conditions on the chosen plot.

  • Changing roof pitch angle – project adaptation allows for an increase/decrease of about 5-10%. It's important, however, that the entire building structure is adapted to the changes.

  • Project orientation – project adaptation can involve creating a precise mirrored reflection of the design.

  • Decorative elements.

The above-mentioned changes must be implemented before obtaining a construction permit. An authorized architect must carry them out, marking the planned changes in red on the original design.

Can Changes be Made to the Project After Obtaining a Building Permit?

It's worth knowing that some changes can be made after obtaining a construction permit. Investors often ask us what changes can be made in this way. In this case, it's important to use the distinction between significant and insignificant changes.

As significant changes, the following are defined:

  • Change in building footprint,

  • Change in building volume,

  • Change in height, width, shape of the building,

  • Change in building orientation relative to the plot boundaries,

  • Change in the use of the house or a part of it.

A project adaptation that involves any of the above changes will result in the previous construction permit becoming invalid. Another aspect pertains to insignificant changes, which are modifications not requiring the investor to obtain a new construction permit. However, it's important to note that the construction site manager does not implement such changes. They can only suggest a chosen modification, but it's the adapting designer who is responsible for its implementation.

Insignificant changes in project adaptation include, for example:

  • Change of materials used,

  • Change in the layout of electrical/heating/water installations,

  • Room purposes – as long as they still fall within residential use. If part of the house is intended for commercial use, obtaining a permit will be necessary.

  • Modification of location, number, shape, size of windows and doors,

  • Facade adaptation,

  • Change in roof pitch angle, ridge height, or arrangement of roofing, provided it doesn't necessitate changes in the entire building structure and adheres to all regulations and local conditions.

However, it's important to remember that project adaptation after obtaining a permit must also be documented. Each of the carried-out modifications should be described and depicted both textually and graphically by the adapting designer. Once construction is completed, a copy of the modified project along with a notice of completion of work, a statement from the construction site manager and the construction supervision manager regarding the correctness of the implementation, must be provided to the Building Inspection Office. This is crucial, as undocumented project adaptation can result in severe fines.

What is the Cost of Project Adaptation?

In reality, the cost of project adaptation depends on the changes being made. The more and more complex the changes, the higher the price will be.

If you're interested in minor changes such as altering the position of windows, doors, or shifting a partition wall, the cost won't be high. In such cases, the cost of project adaptation is around 500-700 Polish zlotys. However, if you want to make changes to the structural elements, the cost of adaptation will likely be no less than 2500 zlotys and could reach four or five thousand. In addition to this, you'll also need to consider the cost of purchasing the project itself.
