Planning a house build with this template
Why the schedule comes before the first shovel
On a residential job, most of the expensive surprises happen in the gaps between trades. The block crew is ready but the slab has not cured. The electrician shows up for rough-in and the inspector is not booked until next week. A schedule that links each task to the one it depends on shows those gaps weeks ahead, while there is still time to move a delivery or rebook a sub.
This template is built around a masonry and reinforced concrete house, the usual method in much of Latin America, Southern Europe and the Middle East. If you are building with a timber frame, as most new homes in the US are, rename “Structure and slabs” to framing and shorten it. The logic of the sequence stays the same.
The baseline is 139 working days, including about seven weeks for design and permitting. Treat that as a starting point for a mid-sized single-family home. Your permit office, your crew size and the weather will all move it.
Phases, inspections and milestones
Each phase ends with something you can point to: an issued permit, a passed inspection, a house that is dried in. In the US those milestones usually line up with the inspections the building department requires, and in the UK with building control visits. Add them as zero-day milestones so nobody forgets to book them. The numbers below are the template's default durations in working days.
- Design and permits: architectural design (10), engineering designs (10), permits and approvals (15), plus the budget and physical schedule (5), which runs while the permit is under review.
- Foundation and structure: site clearing and setup (5), foundations (15), foundation waterproofing (5), structure and slabs (20). The footing inspection comes before the pour.
- Walls and roofing: masonry (15) and roofing (10). Once the roof is on, the house is dried in and interior trades can work in any weather.
- Building services: electrical and plumbing (12), starting as soon as the structure is up and running alongside the masonry. Rough-in gets inspected before anything is covered.
- Finishing: plaster and subfloor (10), coverings and painting (15), frames and fixtures (8), final inspection and occupancy permit (5), then handover.
Setting it up for your project, step by step
Work through the template in this order. Fixing the outside constraints first saves rework later.
- Check your local permit office for current review times and replace the 15-day permit task with that figure. Plan-check backlogs of several weeks are common in busy cities.
- Set the working calendar: public or bank holidays, your crew's days off and any planned shutdown, such as the week between Christmas and New Year.
- Ask each sub for a duration and a lead time. Windows, doors, cabinets and HVAC equipment can take six to twelve weeks to arrive, so order dates belong in the schedule too.
- Add inspection milestones after foundations, after rough-in and before handover.
- Assign an owner to every task, from the site supervisor to the roofer to the window supplier.
- Share a PDF with the client and the lender, then update percent complete every week once work starts.
Who this template is for
Owner-builders running their own subcontractors. Without a general contractor, the schedule is the only thing tying the trades together. Linked tasks show which sub you need to call next and when.
Small contractors pricing a job. A clear timeline attached to a bid shows the client you have thought about sequencing. It also gives you a reference point when change orders start stretching the dates.
Borrowers on a construction loan. Lenders release money in draws as stages are completed and inspected. A schedule whose milestones match the draw stages (foundation, structure, dried in, completion) makes each draw request easier to back up.
Where house builds usually run late
Delays on residential projects tend to come from the same handful of places. Most of them can be spotted on the Gantt chart long before they hit the site.
- Permits and plan revisions. A missing document or a plan review comment sends drawings back and can cost weeks.
- Weather on open-ground work. Excavation, foundations and concrete pours stop in heavy rain or freezing temperatures. Many builders pad these tasks by 10 to 20 percent when they fall in a wet or cold season.
- Concrete curing. Slabs need time before they carry load. Stripping formwork early to gain a few days is a safety problem.
- Long-lead items ordered too late. If windows are ordered when finishing starts, the house sits waiting for them.
- Inspections requested at the last minute. In busy areas the next slot may be days away, so book as soon as the date is firm.
- Change orders. Moving a wall or upgrading a finish halfway through ripples into every task after it. Re-run the schedule before agreeing to the change.
