The Ridge at Clemson.

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.

Four bars on four cut terraces. Every image on this page is a render of an unbuilt scheme, made from the design geometry after it was fixed. No photograph of a completed building appears anywhere on this page, and no figure is measured off an image.

The move

Terrace the ground instead of flattening it.

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.

Each bar is 200 ft × 34 ft, three storeys, 15 apartments, 54 beds and 22 tuck-under stalls. 200 ft is exactly the maximum building length the ordinance allows.
The tuck-under condition. The enclosure wall runs 15.1 ft from natural grade to the parking slab and is braced at the top by the podium, so it works at rest rather than active.

The amenity

6,600 sq ft indoors, in one building.

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

What the brochure figures come from.

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

Every area, and the sums close.

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.

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

The scheme is unbuildable as the site is zoned today.

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.

Known weakness

What we would tell an investor, unprompted.

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.
