The first step in building a new house is not pouring concrete or ordering lumber. It is deciding where the house will sit, what it will cost, and who will design it, because those three decisions control every decision that follows. Owners who rush this stage end up redesigning, re-permitting, or re-budgeting mid-build, and the guide on how to construct a concrete building step by step assumes the site, the budget, and the drawings were settled before any equipment arrives.
This article covers the pre-construction sequence in order: site evaluation, budget structure, design team assembly, permits, and construction scheduling, with the numbers and checklists owners actually use.
Pre-construction typically runs three to six months for a custom house, and it is the cheapest phase of the project by far. A mistake here costs a few thousand dollars in rework; the same mistake discovered at framing costs tens of thousands. That asymmetry is why builders say a house is won or lost before the first shovel of dirt moves.
Start with the Site, Not the Floor Plan
The lot constrains the house more than the floor plan does. Slope, soil, drainage, utilities, and zoning all arrive with the property, and each one changes the foundation, the layout, and the cost. The step-by-step guide on how to construct a concrete building works through foundation decisions in detail, and every one of those decisions starts with what the ground offers.
The site evaluation checklist
- Soil type and bearing capacity, confirmed with a geotechnical report rather than a neighbor’s opinion
- Slope and drainage, including where water leaves the lot in a heavy rain
- Utility access: water, sewer or septic, power, and gas at the property line
- Zoning and setbacks, plus easements and covenants that restrict what can be built
- Access for delivery trucks, concrete pumps, and equipment
Orientation belongs on the same list. A house that faces the street without considering where the sun rises and sets will pay for that choice in heating, cooling, and lighting bills for decades. Rotate the plan on the lot during design, not after the foundation is poured, because the cost of rotation is zero on paper and enormous in concrete.
When to order a soil test
A geotechnical report costs a fraction of a foundation repair. Order it before the design is finalized so the engineer sizes footings for the actual soil instead of assumptions. On filled ground, the report can change the whole foundation type, which changes the budget line that is hardest to recover. On a sloping lot it determines whether the walk-out basement you want is even buildable.
Budget for the Whole Project, Not Just the House
New-house budgets fail when they cover the structure and ignore the land, the utilities, the permits, and the finishes. A realistic budget separates hard costs, soft costs, and a contingency reserve, and it treats each category with different rules.
The cost breakdown
| Budget category | Typical share of total |
|---|---|
| Land and site work | 15 to 25 percent |
| Design, permits, and fees | 5 to 10 percent |
| Structure and building envelope | 40 to 50 percent |
| Plumbing, electrical, and HVAC | 10 to 15 percent |
| Finishes and fixtures | 10 to 15 percent |
| Contingency reserve | 5 to 10 percent |
Performance targets move these numbers. The podcast on building New Zealand’s first passive house office with Bryce Dunlop describes a team that spent more on the envelope and the mechanical system up front in exchange for near-zero heating demand for the life of the building. The trade-off is the same for a house: higher first cost on the structure, lower operating cost every year after.
Financing belongs in the budget discussion before design starts. Get a pre-approval that states the loan amount, the down payment, and the monthly payment, then design the house to that number instead of designing first and hoping the bank agrees. Construction loans add another layer: they pay out in draws tied to completed phases, so the budget schedule and the draw schedule should match.
The contingency is not extra profit
Plan 5 to 10 percent of the build cost for changes and unknowns, and draw it down only with the same documentation a change order requires. Owners who spend the contingency on upgrades during construction lose the cushion exactly when the schedule slips and the real surprises arrive.
Assemble the Design Team Early
The designer, the engineer, and the builder produce better results when they meet before the drawings are complete. The architect knows what the house should feel like, the engineer knows what will stand up, and the builder knows what the region can actually deliver at a price the budget can absorb.
Design-build versus design-bid-build
In design-build, one firm handles design and construction under a single contract, which shortens the schedule and concentrates responsibility. In design-bid-build, the owner hires a designer, completes the drawings, then takes bids from builders, which produces competitive prices but adds a full procurement cycle. Both models work; the wrong choice is switching models halfway through, because the drawings and the contract language are built for one path or the other.
Whichever model you choose, hold two design review milestones: a schematic review when the layout is first drawn, and a construction document review before the drawings go to permit. At the first review, changes cost time on paper. At the second, they cost money in the field. Most owners who complain about their build skipped one of the two.
Innovation happens in the details
The exterior building innovations from the New Canaan Idea House with builder Arnold Karp show what early collaboration produces: prefabricated assemblies, tested flashing details, and materials chosen for the climate instead of the catalog. Those details are cheap to draw and expensive to invent in the field, so the design phase is where they belong.
Permits, Approvals, and Site Preparation
The permit is the milestone that turns a design into a construction project. Until the jurisdiction approves the drawings, the site stays untouched, no matter how eager the crew is.
What the permit covers
- Building permit: structure, egress, and occupancy
- Electrical permit: service, circuits, and panels
- Plumbing permit: supply, drainage, and venting
- Mechanical permit: heating, cooling, and ventilation
- Grading and erosion control: soil disturbance and stormwater
Site preparation often includes flatwork the permit does not cover, like driveways and walkways. Installing a brick paver walkway is a good example: it fits the site preparation window, can proceed alongside the foundation work, and does not wait on the framing crew, so scheduling it in this phase keeps the outdoor trades busy instead of idle.
Inspections continue after the permit is issued, usually at the foundation, the framing and dry-in, the rough-in of each mechanical trade, and the final. Each inspection is a gate: the crew cannot cover the work until the inspector signs it off. Ask the builder for the inspection schedule when you sign the contract so the dates are not a surprise.
Timing the approvals
Plan review takes weeks in most jurisdictions. File as soon as the drawings are complete, and use the waiting period to lock the construction loan and finalize the builder contract. Many builders quote a start date from the permit issue date, so the approvals become the schedule’s first critical path, and every week of review delay is a week of carrying costs.
Sequence the Build Around the Critical Path
The construction schedule is a chain of dependent tasks, and the first step is deciding which tasks can overlap and which cannot. Overlapping work keeps the site productive; overlapping the wrong tasks causes rework.
What actually happens first
- Clear the lot and establish the building footprint from the survey
- Rough in the underground utilities: sewer, water, and electrical conduit
- Excavate and pour the foundation, then let it cure before loading
- Frame the structure and dry it in against the weather
- Run the mechanical, electrical, and plumbing rough-ins
- Finish the interior, then complete the exterior site work
The same logic applies to projects around the house. Building a copper trellis follows the same order on a small scale: the base goes in first, the frame second, and the finish last, and doing it while the site equipment is already present avoids a second mobilization cost.
Weather windows shape the schedule too. Concrete, roofing, and exterior finishes all have temperature and moisture limits, so the calendar pushes the risky outdoor work into the dry season where it can. Builders who ignore the local climate when ordering the sequence pay for it in winter callbacks.
Ordering long-lead materials
Windows, structural steel, and specialty fixtures have lead times measured in weeks, sometimes months. Place those orders at permit time, not at framing time, and confirm delivery dates at the weekly meeting. A house that waits on a window order is a house with an open wall.
From Footings to Handover: Keeping the Schedule Real
Once construction starts, the owner’s job becomes decisions and payments, and the schedule lives or dies on how fast those decisions arrive.
The decision deadline
Every week the schedule asks for decisions: tile, paint colors, fixtures, cabinet hardware. Builders hold a decision date for each item, and missing it stalls a crew while the owner shops. A simple rule keeps the build moving: treat every builder question as a 48-hour deadline.
The step-by-step process for multi-storey building construction shows the same discipline at a larger scale: structure first, services second, finishes last, with an inspection gate between each stage. A single-family house follows the identical logic with fewer floors and shorter lead times.
The walkthrough
The last step is the punch list walkthrough, where the owner and builder go room by room and write down every incomplete or defective item. Schedule it after the house is clean, bring the contract documents, and do not sign the final certificate until the list is finished. The certificate of occupancy from the building department is the official end of construction, and the punch list is the owner’s own version of that gate.
That walkthrough closes the loop that opened months earlier at the lot line. The site evaluation, the budget, the design team, the permits, and the schedule were all steps toward one goal: a house that matches the drawings, the price, and the promise made at the first meeting. Get the first step right and every step after it gets easier.
