John asked what another 300 square feet would buy. This is that unit, and the leasing brochure has a real plan for it, so this page is traced rather than assumed. It publishes at ±1,200 sq ft — which makes the true gain over Suite E about 228 sq ft, not 300.
Layouts A and B were 8 McLaren Suite E. John picked B, everything against the walls. This is Option C: the same perimeter-first idea, in the larger suite. It is meant to be read beside the other two, not instead of them.
One name, two spellings. The brochure calls this Suite L; the request called it unit L, and the page lives at /mclaren-unit-l. Same unit — and note it is 6 McLaren, a different building from Suite E at 8 McLaren.
Three things change against the Suite E plan, and only one of them is floor area:
John wrote that he might not need the sink with the cleaning unit I’m looking at. The plan adds something to that: Suite L’s restroom is already plumbed, with a lavatory and a toilet, about 4.5 ft from where the wash line would go. So the real question is not sink-or-cleaning-unit. It is which of three things does which job.
| Job | Existing restroom lavatory | Cleaning unit / ultrasonic | Dedicated utility sink |
|---|---|---|---|
| Hand washing, small rinse | yes — already there | no | redundant |
| A 20×20×12 in part | no — a lavatory bowl will not take it | yes — this is what it is for | yes |
| Filling and draining the tank | possible but awkward, and it is the restroom | — | yes, with a drainboard |
| SW-100 support waste | never | produces it | never to sewer |
What a restroom lavatory can and cannot take. It is a hand-wash fixture on a sanitary branch sized for a hand-wash fixture. Rinse water is fine. Dissolved SW-100, resin, slurry, abrasive or solids are not — not because the drain will block today, but because it puts process waste into the building’s sanitary line, which is the landlord’s problem and then John’s. The wastewater drums stay in the plan whatever he decides about the sink; they are collected and hauled, and nothing about the existing restroom changes that.
So: the dedicated wash sink becomes optional, and the plan draws it that way. If the cleaning unit handles big parts, element 8 can come out and the suite still has a sink — which was not true of the garage. What the existing restroom really buys is not the basin, it is the short tie-in: supply and waste are already at that wall, so adding a utility sink later is a few feet of pipe rather than a new run.
Worth asking the landlord what the restroom waste line will accept before anything is plumbed into it, and worth confirming that a parts-wash fixture is allowed at all.
John asked whether the machines need an enclosure if this goes into a warehouse. Here is the trade-off, and then the room drawn to scale. Nothing here decides it — both options are live, and one of them costs money the other does not.
The number that drives most of this is Mimaki’s, not mine. The 3DUJ-553 will operate from 59–95°F, but colour and dimensional accuracy are only guaranteed between 68–77°F (20–25°C), with humidity at 35–65 % RH, non-condensing. Those are the same figures the garage page was built on, from the Site Requirements Guide. A warehouse shell is not normally held inside that narrow band; a small room can be.
| Enclosed print room | Open warehouse placement | |
|---|---|---|
| Dust and debris | A sealed room with a door is the only thing here that actually excludes concrete dust. Matters most at the print head and in open material. | Bare warehouse slabs shed fines, and forklift and door traffic keep them airborne. Nothing in the layout stops that. |
| Climate — holding 68–77°F | Conditions 331 sq ft, about 4,632 cu ft at the published 14 ft height. | Conditions 932 sq ft / 13,053 cu ft to achieve the same thing — roughly 2.8× the volume, every hour it runs. |
| Noise | Contained, and it is a partition between the machines and the reception rather than the whole suite. | Carries across an open shell; the reception is the room that notices. |
| Fire and code separation | Verify with the city. Building a room inside a leased shell is tenant improvement work and can touch occupancy, egress, sprinkler coverage and alarm layout. This page does not rule on any of it. | Verify with the city. Fewer constructed elements is not the same as fewer obligations, and the equipment and its materials are identical either way. |
| Service access | The partition lands exactly on Mimaki’s service envelopes, so a technician keeps the clearance — but see the tolerance note below. | Unrestricted on every side. This is the option a service engineer would pick. |
| Security | A lockable door around the machines, separate from whoever else holds keys to the suite. | Whatever the suite’s own locks give, and nothing more. |
| Cost | Build cost, plus a permit question. | None. |
The dashed amber rectangle on the plan above is the print room: 9.40 × 35.20 ft = 331 sq ft, wrapping all four service envelopes, with a 3.0 ft door in its south wall hinged on the east jamb and swinging out into the warehouse. It was sized by the constraints, not by eye:
There is no construction tolerance in the east wall. It lands at x = 9.40 ft, exactly on the service envelopes. Push it even six inches east and the walkway past the shelving drops to about 3.4 ft, below the 3.93 ft this page publishes. If the builder needs those six inches, the shelving (element 10) is what moves — it is the only thing creating that pinch, and it is fit-out. The south wall at y = 35.20 ft is flush to machine 4 the same way.
On ventilation this changes nothing and decides nothing. No extraction is drawn here either. It is honest to say a room makes any future extraction simpler — a contained volume is easier to duct and to balance than an open shell — but that is an argument available later, not a decision taken now, and the equipment positions do not depend on it.
Each opening was measured as a gap in a wall run. Which jamb a door hangs on, and which way it swings, came from fitting a circle to the drawn arc and taking its centre as the hinge — not from reading the picture by eye.
| Entry door | Warehouse / reception | Restroom door | |
|---|---|---|---|
| In which wall | reception south, y = 40.59 ft | reception north, y = 26.31 ft | restroom west, x = 19.04 ft |
| Opening (gap in the wall) | 19.96 – 22.87 ft → 2.91 ft | 15.63 – 18.53 ft → 2.91 ft | 23.10 – 25.95 ft → 2.86 ft |
| Leaf, from the arc | 3.06 ft | 2.96 ft | 3.01 ft |
| Hinged on | west jamb | east jamb | south jamb |
| Swings | south, out of the suite | north, into the vestibule | east, into the restroom |
| Kept clear here | 5.0 ft approach, reception side | whole swing, vestibule side | 4.0 ft approach, vestibule side |
The same two doors crowd each other here as at Suite E, and again it is the building, not the layout. The restroom jamb and the reception door hinge are 0.62 ft apart. The reception door standing fully open lies across the approach to the restroom door. Both work; both at once is awkward, and no arrangement of equipment fixes it. That is why the whole vestibule is held clear and nothing is drawn in it.
The clear zones drawn are the generous reading: 5.0 ft on the pull side of the entry door, 4.0 ft on the push side of the restroom door, and the reception door’s whole swing. What actually applies to a suite this size is the building department’s call, not mine.
There is one continuous walkway from the ground-level door to both exits. It never narrows below 3.93 ft:
| Where | Between | Clear width |
|---|---|---|
| Beside the machine column | x 9.40 → 14.53 ft | 5.13 ft |
| Past the shelving — the narrowest point | x 9.40 → 13.33 ft | 3.93 ft |
| Across the vestibule to the reception door | x 14.53 → 19.04 ft | 4.51 ft |
| Ground-level door landing | x 1.80 → 14.53 ft | 12.73 ft |
| North bay, across the top | x 9.40 → 19.04 ft | 9.64 ft |
The 3.93 ft pinch is caused by the shelving, which is fit-out. Move the shelving and it goes back to 5.13 ft. Nothing structural creates it.
Every element above, tested against every door clear zone: 0 blockages. Also tested: no element overlaps another (0 found), and no element is drawn outside the warehouse — in the restroom, the reception, or past an outside wall (0 found). The test is rectangle intersection on the same coordinates the drawing is made from, so the drawing cannot disagree with this result.
| Zone held clear | Extent | Area | Result |
|---|---|---|---|
| Ground-level door landing, 5.0 ft deep | x 3.49–11.14, y 39.56–44.56 | 38.2 sq ft | clear |
| Entry door approach, reception side, 5.0 ft | x 19.96–22.87, y 35.59–40.59 | 14.5 sq ft | clear |
| Warehouse / reception door swing | x 15.58–18.53, y 23.35–26.31 | 8.7 sq ft | clear |
| Restroom door approach, vestibule side, 4.0 ft | x 15.04–19.04, y 23.10–25.95 | 11.4 sq ft | clear |
| Vestibule — kept wholly clear, it serves two doors | x 14.53–19.04, y 18.25–26.31 | 36.4 sq ft | clear |
| Print-room door swing, warehouse side | x 5.00–8.00, y 35.20–38.20 | 9.0 sq ft | clear |
A clean result here means nothing is drawn where a door needs to move. It does not mean the clear zones are the right ones — those are the generous reading described above, not a code citation.
| # | Element | Footprint, ft | Area | Why it sits there |
|---|---|---|---|---|
| 1 | Mimaki 3DUJ-553 — machine 1 | 9.40 × 8.80 | 82.7 sq ft | North-west corner. Body is 7.42 × 4.92 ft; the rectangle drawn is Mimaki’s service envelope. |
| 2 | Mimaki 3DUJ-553 — machine 2 | 9.40 × 8.80 | 82.7 sq ft | Second in the west column. The column runs down the longest wall in the suite. |
| 3 | Mimaki 3DUJ-553 — machine 3 | 9.40 × 8.80 | 82.7 sq ft | Crosses the line where the north bay becomes the west leg — no wall there, so nothing to clear. |
| 4 | Mimaki 3DUJ-553 — machine 4 | 9.40 × 8.80 | 82.7 sq ft | Last one in, and the furthest south. Stops well clear of the ground-level door. |
| 5 | Metal printer bay, RESERVED | 9.00 × 8.00 | 72.0 sq ft | Held empty against the north and east walls. No model named, so this is floor set aside, not a design. |
| 6 | Wastewater drums, 2-drum spill pallet | 4.25 × 2.17 | 9.2 sq ft | North of the wash line and reachable without crossing it. SW-100 cannot go to sewer — these are collected and hauled. |
| 7 | Three-tank ultrasonic | 5.50 × 3.00 | 16.5 sq ft | Against the restroom’s wet wall. Takes the 20×20×12 in part John quoted. |
| 8 | Utility sink + drainboard | 3.00 × 2.50 | 7.5 sq ft | Also on the wet wall, a few feet from the restroom’s existing supply and waste. Optional — see the sink section. |
| 9 | Workbench | 1.80 × 8.00 | 14.4 sq ft | West wall, south of the machine column. Kept shallow so it stays out of the door landing. |
| 10 | Shelving / material storage | 1.20 × 10.00 | 12.0 sq ft | Against the reception wall. This is the one thing that narrows the main walkway, and it is why the walkway measures 3.93 ft. |
| 11 | Electrical sub-panel | 0.60 × 2.30 | — | Position proposed. The existing service location is not shown on the brochure. |
| Everything above | — | 463.9 sq ft | Of 932.4 sq ft of warehouse. Leaves 468.5 sq ft to move in. |
The brochure lists 100 Amps, 120–208V, 3 Phase under the property highlights, and adds its own (verify). At 100 A and 208 V three-phase that is about 36,027 VA. Nothing about the larger suite changes this table — it is the same four machines.
| Load | Qty | Watts each | Watts | Of service |
|---|---|---|---|---|
| Mimaki 3DUJ-553 | 4 | 1,630 | 6,520 | 18.1% |
| Ultrasonic support removal, heated | 1 | ~1,500 | 1,500 | — |
| Bench, lighting, small tools | — | ~1,000 | 1,000 | — |
| Printing and finishing | 9,020 | 25.0% | ||
| Extraction — only if the filter option is taken | 2 | ~370 | 740 | — |
| With extraction | 9,760 | 27.1% |
Headroom is not the constraint here. The figures for anything other than the printers are estimates and should be replaced with the nameplate of whatever is actually bought — and the service itself still needs the verification the brochure asks for. A reserved metal printer is not in this table at all, because no model has been named.
No decision is made here and no extraction is drawn. The garage page shows one option; whether this suite gets filtration units beside the machines, a ducted extract, or something that uses the 14 ft height, is still open. It changes the power line above by about 740 W and nothing else on this layout — the equipment positions do not depend on it.
From John’s own list, and unchanged by the bigger suite except in where it sits:
A crated 3DUJ-553 is 5.9 ft across its narrow face.
Measure the ground-level door before ordering anything. 7.65 ft against a 5.9 ft crate is comfortable — but that figure is scaled off a leasing brochure that carries no door dimension at all. A door symbol on a brochure is drawn to look right, not to be measured. Clear width and clear height, on site, with a tape.
Only a handful of numbers here come from the landlord. Everything else is measured off the drawing, and is labelled as such.
| Published by the brochure | Scaled off the drawing by me |
|---|---|
| ±1,200 SF (6 McLaren, Suite L) | every wall, room and door position |
| 14 ft minimum clear height | 28.14 × 44.56 ft overall |
| ground-level doors | ground-level door 7.65 ft wide |
| 100 A, 120–208 V, 3 phase (verify) | all three interior openings, swings and leaf lengths |
The one check worth reporting. The scale was set so the suite outline closes on the published area, so that it closes proves nothing. What does mean something: the three door leaves were not used to set the scale, and they fall out at 3.06, 2.96 and 3.01 ft — three ordinary 3 ft doors. A wrong scale would have to be wrong by the same factor in a quantity it never saw. Drawn from the measured walls the suite comes out at 1200.0 sq ft: warehouse 932.4, restroom 73.3, reception 194.3.
The three property figures above are listed for the whole of Irvine Business Center — several suites across several buildings — not for Suite L specifically. The brochure also states plainly that nothing in it is an offer or a warranty.
| 8 McLaren Suite E | 6 McLaren Suite L | |
|---|---|---|
| Published area | ±972 SF | ±1,200 SF |
| Machines | 4, two across two deep | 4, one column on the long wall |
| Reserved metal bay | 38.8 sq ft | 72.0 sq ft |
| Free floor after fit-out | 351.6 sq ft | 468.5 sq ft |
| Ground-level door, scaled | 6.4 ft | 7.65 ft |
| Crate order | east column first, aisle is narrower than the crate | north first; no crate passes a placed machine |
| Existing sink in the suite | restroom, a few feet away | restroom lavatory, drawn |
| Reception / office | 140.0 sq ft | 194.3 sq ft |
| Cost | rent, ongoing | rent, ongoing — and more of it |
The extra 228 sq ft is real but it is not the reason to prefer this one. The reasons are the single wall long enough to take all four machines in a row, the wider ground-level door, and a restroom that is already plumbed next to where the wash line goes.
