How long does it take to build a detached house? What affects completion times and how to avoid delays

How long does it take to build a house in theory?

You will often come across the opinion that it takes between 12 and 24 months to build a detached house. However, this is only an indicative range and not a guarantee that after two years the keys will already be in your pocket. No wonder many builders ask the question: how long does it take to build a house in practice and whether this time can be reduced.

On paper, everything looks simple: there is a construction schedule and each stage has a deadline. In practice, the pace is determined by the availability of construction crews and materials, as well as the seasonality of the work. Delayed deliveries or a shortage of tradesmen can postpone the next steps by weeks, and winter weather slows down the whole pace of construction.

Coordinating the investment yourself, the so-called economic system, often adds to the construction time of the house, because any clash of dates or simply our inexperience in organising this type of event has a negative impact on the wholei. It is therefore advisable to use the theoretically stated ranges as a guideline.

What does the real time of house construction depend on?

Although everything seems predictable in theory, there will always be something on the construction site that changes the plan. The actual construction time depends on many elements - from the design to the organisation to the decisions made during. Not surprisingly, investors most often ask how long it takes to build a house in practice and what the differences between the plan and reality depend on.

The project and its complexity

The simpler the body and roof, the quicker the various stages of construction can be completed. A simple plan, limited number of details and an uncomplicated roof truss allow the load-bearing walls and external walls to be erected more efficiently. Large glazing, cellars or unusual solutions mean more deliveries, additional crews and longer construction times.

Construction organisation system

The choice of work organisation model has a huge impact on how long construction takes. When everything is overseen by one company and a designated construction manager, the schedule is consistent and there is no downtime between teams. In the economic system, the developer coordinates the work himself, and the biggest delays occur precisely in the „gaps” between successive contractors.

Weather and ground conditions

Rain, frost or waterlogged ground can delay earthworks, foundations and plastering. This is why proper site preparation is so important. Sometimes, in difficult conditions, some stages cannot be accelerated - regardless of the technology chosen and the availability of teams.

Investor decision-making

Efficient approval of the choice of building materials, detailed design or changes facilitates the smooth implementation of the project. Every delay in the decisions extends the time and increases the costs - this applies for example to the purchase of joinery or external doors. It is worth remembering that at many stages, e.g. before making connections or moving to the raw state, it is necessary for the investor to approve the documents and arrangements and formally notify the construction. In practice, it is these decisions that most often determine how long it takes to build a house from the moment the first works start until final acceptance.

Example of construction schedule

How long does it take to build a house? With efficient organisation and a well-prepared plan, it is possible to build a house at a predictable rhythm. The final time depends on the complexity of the block, the chosen technology and the availability of teams, but with standard assumptions the pace of construction looks more or less like this:

0-2 months - design and paperwork

This is the moment to prepare the documentation and the construction project. The choice between pre-designed and customised versions is all about pace - the former allows you to get off to a quicker start, the latter gives you a better fit for the plot. It is also the time for permits and preparation for the start of construction. It is essential to have the building delineated, which determines its exact position on the plot and allows ground work to begin.

3-6 months - raw state

Once the plot has been prepared, earthworks begin, followed by the construction of the foundations. Then the walls, ceilings and roof are built. Increasingly, builders are opting for cellular concrete blocks, which speed up the work and make it easier to reach zero state. The roof, which closes the building, is also crucial at this stage. It is worth mentioning that when the building has reached the "shell and core" stage (i.e. with all windows and doors in place), the investor can be sure that the house is protected against the weather and that further work can begin.

6-10 months - installation and finishing

The next phase is to carry out the installations, plastering and flooring, followed by the finishing work. The schedule can be shortened if some of the prefabricated elements are used, but traditional technology works just as well.

10-12 months - acceptance and completion

At this stage, the investment takes its final shape. The house is prepared for interior decoration or for living in - depending on the standard the investor intended. For some, it is the moment of finishing, for others - fulfilment of the dream of a dream home. The whole process is completed with formal technical acceptance, notification of the completion of the construction to the relevant office and closure of the documentation. Looking at all the stages, it is easier to understand how long it takes to build a house from the first foundations to the commissioning of the investment.

At DD Projekt, building a house is a planned process - not a guessing game

At DD Projekt, everything follows a clear plan. Thanks to this, the investor knows in real time what is happening on the construction site - from the open shell, through installations and finishing works, to final acceptance. Already at the stage of discussions, the question of how long it takes to build a house often arises, which is why we prepare a reliable estimate even before the contract is signed.

What we provide:

• A realistic estimate of how long the house will take to build, even before the contract is signed - with a margin of error of +/- 10%.
• A permanent team carrying out construction work with no downtime between phases.
• Clear construction schedule, supported by photo documentation and construction log entries.
• Possibility to choose the standard of construction of the house - from the „to move in” variant to full turnkey finishing.

Typical house construction schedule

The average construction time for a house with DD Projekt is 9-14 months, depending on the size of the project and the speed of the investor's decision. 

During this time, we carry out everything from the erection of the external walls and partition walls, to the installations and insulation of the facade, right through to the final details.

For many people, it is at this stage that the question of how long it takes to build a house in practice arises - we answer it by showing a detailed plan and eliminating schedule downtime. With constant coordination, we can also effectively reduce the time it takes to build a house by eliminating schedule downtime.

Don't want to guess when you'll be living in your own home? Choose DD Projekt - we'll design, build and finish your home on schedule. No chaos, delays or surprises.
