Chambers360 — sources, scale and accuracy

Updated 15 October 2026. 360 Chambers Street, Phillipsburg, New Jersey.

This model combines online records and actual aerial LiDAR with the owner's property photographs and videos. It is a source-backed reconstruction of the visible property and a proposed entertainment campus. It is not a measured as-built survey or a complete photogrammetric scan. No source located supplies a complete current floor plan or surveyed tunnel route.

Online evidence used

Source	What it supports	Important limit
NJOGIS parcel mapping	Actual mapped polygon shapes of Block 1411 Lots 32, 33 and 34	GIS boundaries are planning references, not legal survey lines. Owner confirmed the pictured land is in the project scope.
Official parcel metadata	Provenance and limits of the parcel geometry	Does not establish title, setbacks or permission to build.
2020 NJOGIS one-foot aerial imagery	Historic-building footprint, roads, drive, gravel parking, lawn, hill and canopy alignment	Canopy occlusion, building lean and the imagery's age limit precision.
New Jersey elevation program	Official elevation program and collection provenance	Historical aerial capture, not a new site visit.
Actual Northwest NJ 2018 LiDAR tile C7B7	Downloaded classified point cloud: 39,894 returns in the local study area, including 24,054 ground-class returns	2017/2018 collection; aerial observations do not reveal interiors, hidden walls or tunnels. Unclassified returns are not automatically labeled as buildings or trees.
NJOGIS 10-foot DEM	Earlier terrain reference and study datum	Superseded for this revision's site ground by direct LiDAR interpolation. The greenhouse's earlier floor level is retained.
Google Maps / Street View	Exterior comparison, including the August 2024 street imagery inspected during the earlier pass	No Google 3D mesh, tiles or copyrighted panorama is redistributed.
NJParcels cross-check	Address, block/lot and additional-lot leads	Secondary source. Not a measured building plan or title certification.
NJDEP building-footprint service	Checked for available footprints	Query returned no usable footprint for the study; no dimensions were inferred from a missing result.

The raw LiDAR uses New Jersey State Plane US survey feet and NAVD88/Geoid12B elevations. It was transformed into the existing local metre-based model frame. A 0.5-metre interpolation grid was produced from ground-class returns. Grid spacing is not a measurement-accuracy claim. The editable Blender file contains the actual local returns in a separate hidden evidence collection. The scan is not a facade or basement scan. An illustrative terrain continuation outside the finite LiDAR grid blends the display edge into the surrounding context; it does not alter the site grid.

Property footage incorporated

The latest 24 photos show the rear annex, horizontal siding, tall exterior fire stair, parking slope, front parking tree, lawn, and two adjacent lawn trees beside a picnic table. The new IMG_5628 and IMG_5595 videos were sampled at 30 frames each. Earlier drone and property clips, the basement media, and map screenshots remain references. These give visual relationships and finishes; they do not supply survey control or complete overlapping coverage for an exact reconstruction.

The original historic building, driveway and parking remain in their established locations. The new building sits at the rear. A third distinct tree is now represented: two lawn trees in the court, plus the parking tree. The second lawn-tree center is estimated from the photo relationship, not a surveyed coordinate. Two earlier illustrative background trees were removed from the mock-up because their estimated canopies conflicted with the relocated roof. This does not propose removing the three principal retained trees or certify the inventory of other site trees.

Current proposal geometry

Central hall: 13.8 × 21.9 m, about 302.22 m² / 3,253 square feet, with stage, glass headquarters, internal balcony and stair.
Ground footprint: about 802.79 m² / 8,641 square feet including the connecting wings and circulation.
Model footprint check: zero area outside the mapped three-parcel union and zero overlap with the image-traced retained parking polygon. The footprint sits close to some mapped edges; it has not been checked against a legally surveyed setback envelope.
Two music suites, each with control/live/vocal rooms; two podcast rooms; connecting glazed galleries; backstage dressing and washrooms; offices; rooftop lounge/bar; lower club and washrooms; one greenhouse dome.
Wedding illustration: eight round tables with eight chairs each, 64 places. Seated-performance illustration: 218 chairs plus four reserved positions. These are furniture arrangements, not approved attendance or occupancy limits.
Ground floor +0.50 m; HQ +4.10 m; roof +7.95 m; club −3.10 m in the study datum.
New connector centerline: approximately 48.54 m. It is separate from the owner-reported original 60-foot passage, whose previous model is retained.

The building wraps an open-air court instead of enclosing tree trunks in rooms. Illustrative 6 m trunk buffers are used for planning; nearest proposed footprint distances are approximately 6.85 m and 6.80 m at the lawn trees. These are not arborist-approved root protection zones. Foundation design, root mapping, drainage and canopy care remain unresolved. The model's club and proposed corridor are routed outside the illustrated court.

History: what the sources establish

The 2002 New Jersey Historical Commission report includes Eagle Hotel at Stockton and Chambers in its surviving-site list and also discusses claimed sites visited. Phillipsburg's June 2026 proclamation recognizes the site's association. Those sources do not date or map the owner's specific passage.

2002 state report, surviving-site list
Phillipsburg June 9, 2026 agenda packet, proclamation
1890 Sanborn map catalog: a comparable corner footprint is labeled Carpets. Historical numbering must be resolved before identifying occupants.
1903 Sanborn sheet 5: 360 Chambers is labeled Sal. & D., supporting saloon/dwelling use by that date.
Phillipsburg Railroad Historians photograph: the archive identifies the mansard-roofed Eagle Hotel in the townscape. The steam railroad context is distinct from the Underground Railroad freedom movement.
Gerald Stern reading Lucky Life: a literary connection to the Eagle Hotel, not architectural evidence.
Warren County land records guide: a route for a future inspected chain of title; no deed image or chain of title was obtained in this research.

No verified exact construction year, named freedom seeker who used this particular passage, or historical tunnel plan was found. Hidden geometry, materials and connection to the new club remain expressly proposed. The earlier original basement tour retains its source-linked historical interpretation.

Model and sharing quality

The Blender master retains the detailed geometry and packed 4K furniture textures. The browser version uses compressed geometry, 2K furniture textures and reduced distant foliage for loading and movement. No claim is made that its realtime lighting equals the separately rendered Cycles stills. Real furniture models come from Poly Haven under CC0; all are credited separately.

Walk using WASD or arrow keys, drag to turn, Shift to move faster, and Escape to stop. Character view can switch to first person; close walls automatically shorten the following camera. Continuous stairs connect the modeled levels; destination shortcuts remain optional. The main hall-to-studio circulation is modeled continuously; this is a design simulator, not an egress analysis or physical-occupancy approval.

What is needed for an exact replica

A current boundary/topographic survey, measured facade/interior dimensions, full overlapping site capture with scale control, surveyed trunk/canopy positions, and a professionally documented tunnel investigation would resolve the remaining geometry. Online aerial data and unmeasured footage cannot reveal surfaces they never observed. No demolition, excavation or construction clearance is implied by this visualization.
