Introduction
This case study is hypothetical and illustrative — a worked example showing how the estimating process fits together end to end, not a report of a real project. All quantities, costs, and timelines are planning figures.
Meet the project: a homeowner wants a freestanding brick garden wall along a side boundary — 20 ft (6.10 m) long, 9 courses high (23.625 in / 0.60 m, about 2 ft), single wythe, running bond, with a brick pier at each end. Non-structural, non-retaining, on flat ground. Below is the full pass: measuring, estimating, costing, ordering, and scheduling, using the Brick Wall Calculator logic at each step.
The Plan
- Wall: 20 ft long × 9 courses (23.625 in) high, single wythe, running bond, modular brick, 3/8 in joints.
- Piers: two end piers, nominal 8 × 8 in square, 9 courses high, with a cap course each.
- Footing: concrete strip footing (estimated separately — see the Concrete Calculator).
- Mortar: Type N premixed bags (see the material guide for why).
- Permit check: at ~2 ft high, non-retaining, this wall falls below typical permit thresholds — but the hypothetical homeowner still confirms with the local building authority (per the code compliance guide) before ordering.
The Estimate
This wall is a good candidate for the course-counting method, which counts actual bricks and serves as an exact cross-check of the area method:
Wall bricks: 20 ft = 240 in ÷ 8 in per stretcher = 30 stretchers per course × 9 courses = 270 bricks.
Pier bricks: each 8-in-square pier lays 4 bricks per course × 9 courses = 36, plus a 4-brick cap = 40 per pier × 2 piers = 80 bricks.
Net count: 270 + 80 = 350 bricks.
Area-method check: wall face = 20 ft × 1.97 ft ≈ 39.4 sq ft × 6.55 ≈ 258 bricks; piers ≈ 2 × (2.67 ft perimeter × 1.97 ft) × 6.55 ≈ 69 + caps → the two methods land within ~5% of each other, which is the expected agreement band (the area method approximates; the course count is exact). Because coursing is a pure count, it is identical in metric: the same 6.10 m wall lays 30 stretchers of 203 mm per course × 9 courses of 66.7 mm = 350 bricks — the unit system never changes a brick count.
Waste: running bond, straight runs, two piers → 10%: 350 × 1.10 = 385 → 385 bricks to order.
Mortar: 385 ÷ 1,000 × 7.5 = 2.89 → 3 bags (80 lb), plus 1 spare = 4 bags on the ticket.
The Budget (Illustrative)
Using mid-range 2026 planning figures (not quotes — see the cost guide for ranges):
| Line item | Quantity | Illustrative cost |
|---|---|---|
| Bricks (modular, ~$0.80) | 385 | ~$308 |
| Mortar mix (80 lb, ~$11) | 4 bags | ~$44 |
| Pier caps / coping | 2 + wall cap | ~$40–$80 |
| Delivery (one pallet + mortar) | 1 trip | ~$75–$150 |
| Tools (basic kit, first-timer) | 1 set | ~$150–$300 |
| Materials + tools subtotal | ~$617–$982 |
DIY labor: free but slow — at a beginner’s 50–100 bricks/day, 385 bricks is 4–8 days of laying plus footing work. A mason’s quote for the same wall would add the labor line (often exceeding materials on small jobs) but compress the schedule to 1–2 days. The DIY vs pro guide frames that trade-off.
The Order
385 bricks is short of a full pallet (~500–550), so the hypothetical order goes out as a partial pallet / banded cube of 400 (rounded up from 385 — rounding to the supplier’s convenient quantity), 4 bags of Type N mortar, and the caps — one batch, one delivery ticket, per the pro tips on batch discipline. Delivery is scheduled after the footing is poured and cured, so pallets land on a site that’s ready to lay, not on a site that’s still being dug.
The Schedule (Illustrative)
- Day 1–2: confirm permit exemption with the building authority; call utility locate; set out the line.
- Day 3: excavate and pour the footing (concrete work — see the Concrete Calculator).
- Day 4–6: footing cures; bricks and mortar delivered and stored under cover.
- Day 7: dry-lay first course, set the story pole, mark coursing.
- Day 8–12: lay the wall (beginner pace), building piers as the courses rise.
- Day 13: set caps, final jointing check, cleanup.
Lessons the Example Teaches
- Course counting beats area math on coursed work — it’s exact, unit-independent, and doubles as the layout plan.
- Piers are never negligible — two small piers added 80 bricks, nearly a quarter of the wall’s count. Uncounted piers are a classic shortfall cause (common mistakes).
- The permit check costs nothing and precedes everything.
- Schedule the delivery to the work, not the calendar — bricks arriving before the footing is ready just sit in the weather.

Frequently Asked Questions
Is this case study a real project?
No — it’s hypothetical and illustrative, constructed to demonstrate the estimating workflow. Quantities follow the same formulas as the calculator; costs are illustrative planning ranges, not quotes.
Why did course counting give a different number than the area method?
Course counting tallies actual bricks in the actual grid; the area method approximates from face area. They should agree within ~5–10% — here 350 (exact count) vs ~330 (area estimate including piers). Larger gaps signal an input error.
How long would this project really take?
At a beginner’s 50–100 bricks/day, the 385-brick wall is roughly a week of laying plus footing and curing time — about two weeks elapsed. A professional mason would lay it in 1–2 days.
Get Your Number
Your project won’t match this one brick for brick — but the workflow transfers exactly: measure per the estimating guide, count by courses where you can, verify with the area method, add honest waste, price from the cost guide ranges, and run the final numbers through the Brick Wall Calculator before you order.
