Product line 02 · worked example
60 apartments, 216 beds, four three-storey buildings stepping down 101 feet of wooded hillside, with the parking tucked underneath. A complete concept package — a leasing brochure and nineteen drawing sheets — for a real site on Singleton Street at Rose Hill Road in Clemson, Pickens County, South Carolina.
60 apartments: 48 at four bed / four bath, 12 at two bed / two bath
Four contiguous parcels, one owner, measured on the county GIS polygon — against 7.66 ac claimed by the listing
The site falls from 840 to 739 ft. Mean slope 12.3%, median 19.3%
216 stalls: 88 tuck-under beneath the buildings, 128 on the surface
The move
Most student housing is built on the flattest land somebody could find. This site is the opposite: it falls a hundred feet from its high corner to a creek, and the steepest third of it is mature hardwood and pine. So the buildings step down it on four cut terraces, and the uphill retaining wall of each terrace doubles as the enclosure of the parking tucked beneath the building.
That single decision does three things at once. It recovers 88 parking spaces from ground that could not otherwise hold them. It puts the cars out of the view and out of the weather. And it lets the steep third of the site stay exactly as it is — which is also what satisfies both the 25% open space requirement and the tree retention requirement, with the same ground.
The apartment plan came out of one geometric test. A 64 ft deep double-loaded corridor bar was drawn first and rejected: it left two bedrooms per unit with no window. The unit was made to span the full 34 ft depth of the building instead, so all four bedrooms reach a facade. That test set the building type, the building depth and — through the depth — the earthwork.
The amenity
The clubhouse sits on the highest terrace — the one with the view back down the ridge. Typical student housing delivers 15 to 25 sq ft of indoor amenity per bed. This scheme carries 31.

The drawings
The leasing brochure and the drawing set are generated from one model, so they cannot drift apart: 216 beds, 34.4% open space and 31 sq ft of indoor amenity per bed appear in both because they are read out of the same file. Click any sheet to open it full size.
The site, acre by acre
289,748 sq ft of land accounted for row by row. The last two rows are listed rather than absorbed into the others, because a schedule that closes only by hiding its remainder is not a schedule.
| Item | SF | % | What it is |
|---|---|---|---|
| Residential building footprint | 27,200 | 9.4 | 4 buildings at 6,800 SF each in plan |
| Clubhouse footprint | 6,600 | 2.3 | Single storey, seven spaces scheduled |
| Swimming pool, water surface | 2,560 | 0.9 | Excludes the surrounding paved terrace |
| Surface parking and drive terraces | 42,240 | 14.6 | 128 stalls at 330 SF gross, aisles included |
| Pedestrian spine, paved | 3,084 | 1.1 | 600 ft of lit accessible route |
| Designed green — courts, pool terrace | 16,159 | 5.6 | Common open space under Ord. 19-304.e.f |
| Conserved open space — slope and stream | 82,034 | 28.3 | Retained tree stand, Ord. 19-906; never disturbed |
| Perimeter setback strip | 74,699 | 25.8 | 25 ft to every boundary; no building, no parking |
| Unprogrammed remainder | 35,169 | 12.1 | Planted banks, the eastern wedge, land in reserve |
| Measured site | 289,748 | 100.0 | 6.6517 ac — the sum of every row above |
The 25 ft perimeter setback strip is 74,699 sq ft — a quarter of the site carrying no building and no parking, by rule rather than by choice. Together with the unprogrammed remainder that is 37.9% of the land being bought, and that is the honest read of what this site yields.
Not approved
Multi-family development is a dash on Table 19-302 in the RM-1 and RM-2 districts these four parcels carry. It requires a zoning map amendment to RM-4 plus conditional use approval by the City of Clemson. That, and not survey or design, is the critical path — and the recommended first action in the package is to take the rezoning question to Clemson Planning before spending anything on survey, geotechnical work or design.
| Severity | Open item | Why it matters | What closes it |
|---|---|---|---|
| PREREQUISITE | Multi-family is not permitted in RM-1 or RM-2 | The programme is unbuildable as zoned. A map amendment, not a permit. | City Council rezoning to RM-4, then conditional use |
| PREREQUISITE | No boundary or topographic survey exists | Every dimension is a cadastral compilation; setbacks and areas can move. | Boundary and topographic survey by a PLS licensed in SC |
| PREREQUISITE | No geotechnical report | Site Class D is adopted, not measured. Terrace walls need bearing and global stability. | Geotechnical investigation, borings on each terrace |
| HIGH | Measured 6.65 ac against 7.66 ac claimed | 13.2% of the land does not exist. $195,404 per acre, not $169,683. | Survey plus a title commitment with legal descriptions |
| HIGH | Fire flow for R-2 unverified | If the main cannot deliver it, a tank and pump appear that no sheet makes room for. | Hydrant flow test — the cheapest test that can move this |
| HIGH | Sanitary sewer invert unknown | The site falls 101 ft away from the street. Gravity may not reach. | Utility survey and City of Clemson sewer atlas |
Six of fourteen items from register G-004. The full package carries all of them, each with the party responsible for closing it.
Known weakness
The scheme is held down by where cars fit, not by the ordinance. Density could reach 56 beds per acre — 372 beds — and it stops at 216 because surface parking on a 101 ft hillside runs out first.
The podium is the number that decides it. Tuck-under parking recovers 88 stalls at the price of a structural podium under each building. That cost is not carried in the package, and it will decide whether the scheme is worth building. It should be priced separately from the superstructure.
Open space has 3.3 points of margin. 28.3% against a 25% minimum. Any growth in footprint, drive or terrace eats that first, and a fifth building breaks it outright — which is exactly why the fifth and sixth buildings were deleted from an earlier version of this scheme.
The terrain model is public data. The surface is a USGS 3DEP 10 m model, not a survey. A real survey will move the pad elevations, and with them the terrace walls, which are the largest uncosted item in the scheme.
Send the parcel. You get the same package: the measured site, the yield against the actual zoning ordinance, the buildings drawn on the real terrain, and a register of everything still open with the name of whoever has to close it.
