Benchmark

Where your firm's practice lives.

Benchmark is the system of record for the residential architect who designs the home and sees it built. Price proposals from your firm's real costs, keep a record of every home from first proposal through completion, and turn finished homes into case studies that win the next client. Everything here stays private to your firm.

Explore the data and trends behind your custom home projects.

Every home your firm has designed, priced and seen through construction. Private to your firm.

The Mid-Atlantic market, town by town.

Closed sales of architecturally designed homes and land. Pick a town or county to see what homes sell for, how big they are, and what the land costs.

Market Structure

Lot size defines the design canvas

Median lot ranges from 0.11 acres on coastal markets to 1.34 acres in Hunt Country — a 12× variance in outdoor design canvas. NAHB's national share for Final Steps (landscape, driveway, outdoor structures) is 6.5% — but in acreage-driven markets where the lot becomes the project, the practical share runs noticeably higher. Use the Market Explorer to find submarkets that match your typical acreage profile.

For Landscape Architects

Log your first custom home project

Every project you log unlocks your firm's portfolio benchmarks — $/FSF, cost mix, sub roster — and adds one more data point to the eventual peer-firm benchmark. Start with a project you finished recently; you can always edit later.

Your projects stay in your firm's private workspace. Only your firm can see them. Nothing is shared with other Partner Network members or used to compute market benchmarks.

Where the market pays the most per square foot

Mid-Atlantic submarkets ranked by mean $/FSF (price per finished square foot, above + below grade) for architecturally designed new construction. Submarkets with at least 5 closed home sales (n≥5) shown for benchmark-quality medians. Use as a calibration before pricing a project in an adjacent submarket.

Distributions

Where the market actually clusters

The averages are only half the story. The shapes below show how transactions are spread, and where premiums get paid.

Price per finished square foot ($/FSF)

Distribution of $/FSF (total finished sq ft, above + below grade) across the full sample. Median marked.

Price vs finished size

Each dot is one transaction, colored by market archetype.

Land Economics

Where the land sets the budget

From 996 closed land transactions across the Mid-Atlantic. The top chart shows raw land cost per acre by market; the bottom shows how much of a typical project's cost goes to the lot vs. the build in each market.

Top markets by median land cost per acre

Median $/acre for closed land transactions, all markets with at least one observation shown. This is real dirt cost — not derived from finished home sales. Land coverage is intentionally broader than residential (n≥1) since premium markets with thin land-sale volume still inform the cascade.

Land vs. build cost share by market

For each market's typical project (its own median lot size × median home size), how much goes to land vs. construction. Markets where land dominates the budget appear at the top.

Cost Mix Drift

How the construction-cost mix has shifted, 2013 – 2024

Share of construction cost by major category, from successive NAHB Construction Cost Surveys. Major Systems Rough-ins climbing from 13.4% to 19.2% is the headline — HVAC, electrical, and plumbing costs have outpaced framing and exterior trades over the decade.

Methodology

How this data was built

Same boutique-quality methodology as the published 2025 State of New Construction report — extended to the full Mid-Atlantic dataset (961 architecturally designed spec homes, seven states).

Source

Sales data is drawn from closed transactions across a curated set of architecturally designed spec homes in the Mid-Atlantic, with national cost-share benchmarks from the NAHB 2024 Cost of Construction Survey.

Filters applied

  • Detached single-family homes, fee simple ownership
  • Excludes homes in Home Owner Associations (production-builder skew)
  • Excludes homes not built within the last two years (filters out renovations and resales)
  • Excludes listings with zero above-grade finished square footage (no primary structure to measure)
  • Excludes listings with zero bedrooms or zero full bathrooms (catches accessory structures, sheds, and outbuildings mis-coded as detached single-family)
  • Excludes transactions below NAHB's national average $/FSF ($251/finished sq ft) — computed on total finished square footage (above-grade + below-grade finished). This is the architectural-quality axis: $/FSF self-normalizes for home size and discriminates premium-per-finished-foot from production-builder economics.
  • Excludes transactions below NAHB's national average sale price ($665,298). This is the project-scale axis: it aligns the dataset with the boutique custom market that design professionals and their clients operate in, and filters out smaller transactions that aren't representative of architecturally-designed new construction at the scale this dashboard is built to benchmark.

Geographic scope

Full Mid-Atlantic — seven states (Washington D.C., Maryland, Virginia, Delaware, Pennsylvania, New Jersey, West Virginia), 255 distinct submarkets in the dataset; benchmark-quality reporting requires at least 5 closed home sales (n≥5) per market. The 2025 published State of New Construction report used a 12-county sample; this interactive dashboard expands to the full universe at the same boutique-quality threshold.

Estimator math

Your estimate = land cost (regional observed median $/acre × your target lot) + construction cost (market median total finished $/sqft × your target sqft). Land cost uses a city → county → state cascade against 312 closed land transactions; falls back to NAHB national lot share if no regional data is available for the market. Construction cost expands via NAHB's 8-stage breakdown (I–VIII), each stage expanding to its sub-items (A–AJ). Soft costs (financing, overhead, builder profit, marketing, commission) and design fees are quoted separately by the design pro, builder, and lender — intentionally not in the headline total.
