How long does it take to build a housewith a general contractor?

How long a single-family house takes — the full schedule

The question “how long will construction take” comes up in almost every conversation with an investor right after the question about price — and rightly so. Construction time isn’t a curiosity, it’s a real financial and life parameter. It determines how long you’ll have to pay a mortgage alongside rent, when your children will start at a new school in a new neighborhood, and when the lease on your current apartment will end. A six-month error in the schedule means, in practice, tens of thousands of złoty in additional indirect costs that nobody writes into the construction budget.

The problem is that two completely different messages coexist on the market. Ads from companies building in timber-frame technology promise a house “in 4 months.” Friends who built using the self-managed method talk about five years with stoppages. The truth for a solid brick house built turnkey by a single responsible contractor lies somewhere in between — and it can be described with concrete numbers, not slogans.

In this article, we present a realistic timeline for building a single-family house with a general contractor: how long each stage takes, what most often extends it, and what can actually be done to shorten the timeline without cutting quality. This is material for a conversation with a contractor — not with a marketing department.

The table below shows a realistic construction time for a house of 150–220 m², built in traditional (brick) technology, turnkey, with a general contractor coordinating the entire process. This is a schedule of construction stages for a standard plot, without unusual ground conditions.

What really extends a house build

Most delays don’t come from one big problem, but from a handful of recurring mistakes that can be predicted and prevented already at the planning stage.

Weather. The shell structure and the roof are sensitive to weather conditions — heavy rainfall, frost below -5°C during concrete works, or strong wind during roof truss assembly genuinely stop work. A good schedule accounts for this in advance rather than treating it as a surprise.

Material shortages and long delivery times. Some elements — custom-made joinery, cladding, higher-end HVAC components — have lead times measured in weeks, sometimes months. Ordered too late, they become a bottleneck for the entire construction, even if the rest of the work is on schedule.

Poor subcontractor coordination. This is the most common and most costly cause of delays in construction carried out without a single responsible contractor. The electrical crew waits for the plumber, the plumber waits for the screed, the screed waits for the final decision on underfloor heating — while the investor tries to manually manage the calendars of five different companies.

Administrative formalities. The waiting time for a building permit, utility connection applications, or inspections can be beyond the contractor’s control, but an experienced general contractor knows how to prepare complete documentation the first time, to avoid repeated rounds at the office.

How to speed up construction without losing quality

Shortening construction time at the expense of quality is the worst possible saving — finishing and installation mistakes in a premium house end up costing more than the weeks saved. There are, however, specific practices that genuinely shorten the schedule without touching the standard of execution.

Prefabrication of elements. Roof trusses, joinery elements, or prefabricated structural components prepared off-site shorten assembly time from weeks to days and eliminate weather dependency during production.

Ordering materials in advance. Materials with long lead times — windows, doors, tiles, installation components — are ordered while the previous stage is still underway, not when it becomes urgent. This requires a procurement schedule prepared at the start of construction, not during it.

A schedule with time buffers. A realistic timeline for building a single-family house allows a margin for weather and minor adjustments from the outset, instead of stacking stages back-to-back. Paradoxically, it’s the schedule with buffers that finishes sooner than the schedule that looks perfect on paper — because it doesn’t fall apart at the first unforeseen event.

How Sigvin manages the schedule

At Sigvin, the construction schedule isn’t a document created for the contract and then filed away — it’s a working tool that we update and use to account to the investor on an ongoing basis. We start every project by laying out the stages with realistic, not wishful, deadlines, taking into account the specifics of the plot, the technology, and the finishing standard the investor actually plans for — because a premium house with imported joinery and custom installation solutions has a different procurement rhythm than a house finished to developer standard.

We work under a single general-contractor model, responsible for everything — from the first excavation to the final inspection. This means that coordination of masonry crews, electricians, plumbers, and finishing companies happens on our side, not the investor’s. We order materials with long lead times well in advance, and we build the schedule with buffers for weather and unforeseen situations — that’s why our deadlines rarely slip, and if they ever do, we inform the investor in advance, not on the day of the planned handover.

Our role isn’t just building — it’s also protecting the investor’s interests in dealings with subcontractors, suppliers, and public offices, so that the house construction schedule remains a realistic plan, not a source of financial uncertainty.

Plan your build with a realistic schedule

If you’re planning to build a house and want to know how long the realization of your project will actually take — with a specific date, not an approximate “about a year” — schedule a free consultation with Sigvin. We’ll analyze your plot, design, and expected finishing standard, and present a schedule you can rely on when planning your mortgage, rental, and move.
