Specifying Crestron in the architectural drawing set.

The premise is straightforward: the touchpanel on the wall of a luxury residence is a fixture. It is touched daily, it is read against the architecture, and its placement is a design decision the same as a sconce or a switchplate is. Fixtures belong on the architectural drawings, not on a separate submittal package the AV trade brings to the construction-administration phase.

In our experience — both designing residences and inheriting other people’s — the residences where the technology “belongs” in the architecture are the ones where Crestron was specified into the drawing set from schematic design onward. The residences where the technology feels grafted on were specified after the fact. The cost of doing it right is small. The cost of doing it the other way is paid on every wall of the finished house.

Where the panel actually goes.

A senior engineer reads the architectural plans alongside the design team in schematic design. The output of that read is a panel schedule: which rooms get touchpanels, where the panels sit on the wall, what orientation they are in, and what they replace from the conventional electrical schedule (typically a thermostat, a lighting keypad, and sometimes a security keypad — consolidated to one fixture).

That schedule belongs on the architectural plans. We mark it up the way you would mark up a millwork detail: a tag for the panel, a centerline elevation, an orientation note, and a reference to the panel schedule itself. The schedule is a sheet in the architectural set, not a separate document.

The benefit of having it there is that every other trade reads the architectural drawings. The millwork contractor sees the panel location and prepares a bezel cut. The electrical contractor sees the panel location and pulls the right rough-ins. The framer sees the panel location and leaves a stud bay open. The painter sees the panel location and finishes the wall around it cleanly. None of this happens reliably when the panel only exists on a submittal sheet that gets distributed three weeks before commissioning.

The millwork drawings.

Most luxury residences flush-mount the touchpanel into the wall — either against the drywall finish, or into a millwork panel, or behind a custom bezel. The bezel itself is a fabrication detail and belongs on the millwork drawings.

A Crestron TSW or TS series panel has a specific cut-out dimension and depth requirement. The cut-out is millimetre-precise; the depth requirement depends on the rough-in box and the cabling tail behind it. When we’re composing a residence we hand the millwork contractor a single-page detail per panel location: cut-out dimensions, finish requirements at the edge, a bezel material spec when one is called for, and the rough-in box centerline. That sheet is a millwork detail with our name on it; the millwork contractor stamps it into the millwork set during shop drawings.

The residences where this is skipped tend to have panels that look approximately right at three feet but read off-axis up close — a finish gap, a bezel that’s a different black than the trim, a panel surface that doesn’t sit flush with the millwork around it. Fixable, but only at the cost of cutting the wall back open.

The electrical set.

Crestron is low-voltage but it requires power and Cat6 to every panel. The electrical engineer needs to know each panel location to specify the right rough-in box and to pull a cable schedule. That information belongs on the electrical plans, cross-referenced against the architectural panel schedule.

There are two specific call-outs that consistently get missed when the Crestron specification only lives in the AV submittal. First: dedicated circuits to the equipment rack. The processor rack pulls more current than most low-voltage engineers expect, and on residences with serious AV scope the rack room needs its own panel feed. We specify that on the riser diagram during DD; the electrical engineer signs off on it during CD.

Second: conduit pathways from the rack to each panel location. A Cat6 cable can be pulled through almost anything, but if the conduit isn’t there during framing, the eventual cable run will be improvised — through closets, behind built-ins, along baseboards where it lives forever. The conduit schedule is a low-voltage line on the electrical drawings, not a footnote on a submittal.

The reflected ceiling plans.

A Crestron system rarely lives only on the wall. Ceiling-mounted occupancy sensors, microphones for the voice surface, in-ceiling speakers under Crestron control, and the occasional ceiling-mounted panel in a kitchen or media room all show up on the reflected ceiling plans. The Crestron specification needs to live on the RCP the same way the recessed downlight schedule does.

Occupancy sensors are the most common omission. They’re small, they’re forgettable, and they belong on the RCP because the placement matters — an occupancy sensor over a desk reads differently from one over a bed, and the lighting designer needs to know which is which. The sensor schedule on the RCP is a one-line call-out per device, referenced against the lighting control diagram in the spec book.

Specification vs. drawing.

The drawing set shows where things go. The specification book describes what they are. The distinction matters in luxury residential because the two get conflated more often than they should.

Our typical practice is to specify Crestron by design intent on the drawings (“Wall-mounted Crestron touchpanel, finish per millwork detail”) and to fix specific model numbers in the spec book. That keeps the drawings clean and lets the spec evolve as the project moves — a panel model gets discontinued, Crestron releases a successor, the project shifts orientation and a different panel becomes appropriate. The architectural fixture stays the same; the specific model behind it can change without re-issuing drawings.

The exception is when the panel itself is the design statement — a particular bezel finish, a particular panel size that’s integral to the wall composition. In those cases we lock the model on the architectural drawings and accept the substitution risk. Substitutions in late CD or early CA are rare on this end of the market; usually the panel that gets specified gets installed.

Coordinating with the AV trade.

On most residences we work on, an AV integration firm is delivering the install. Our role is the design and the on-panel surface (see Tahoe and custom Crestron UI); the AV integrator’s role is the rack, the wiring, the field commissioning of the underlying systems. Both roles need to be in the drawing set, and the boundary needs to be drawn cleanly.

The way we draw it: panel locations, mounting details, conduit, and the design intent live in our coordination set (which gets stamped into the architectural drawings during DD/CD). The rack room layout, equipment specification, cable terminations, and field test plan live in the AV integrator’s submittal package. The two sets are issued together at CD and reviewed against each other before construction starts.

When the boundary is drawn cleanly, the AV trade reads the architectural set the same way every other trade does. When it isn’t, the AV trade ends up improvising late in the project — which is when most of the visible disappointment with luxury Crestron systems originates.

Common mistakes.

Panel locations marked too low. The default Crestron mounting height is 48 inches to the centerline. In residences with a coordinated switchplate horizon (typically lower — 42 or 44 inches), the panel needs to drop to match. This is a one-line note on the architectural plan that almost never makes it onto the AV submittal.

Panels at door swings. A touchpanel mounted behind a door swing reads as an oversight on the finished wall. The fix is a thirty-second decision in SD and a ten-thousand-dollar fix in CA. The panel schedule on the architectural plans catches it; the AV submittal usually doesn’t.

Insufficient depth in millwork. A Crestron TS series panel needs about three inches of depth behind the wall surface for the rough-in box, the cabling tail, and the panel’s own depth. Millwork panels narrower than three inches force a surface-mount, which reads completely differently. Catching this at shop-drawing review is the difference between a panel that disappears into the millwork and one that announces itself.

Conduit omissions. Already covered above — the most expensive single mistake in luxury Crestron installations. Either every panel location has conduit from the rack, or the project ends up cabling through closets after framing closes up.

How Intuitiv works it into the set.

For projects we’re engaged on from schematic design, we attend the SD coordination meetings and contribute a panel schedule by the end of SD. From there the schedule rides the same review cadence as the rest of the architectural drawings — updated at DD, finalised at CD, marked up at CA. We’re responsive on the email thread the same way the millwork contractor or the lighting designer is.

For projects engaged later — design development or construction documents — we work backwards. We read the existing drawing set, propose panel locations against the architecture as drawn, and contribute the panel schedule as an addendum that gets bound into the next issue of the architectural set. The drawing-set integrity is preserved.

For projects engaged at construction administration or commissioning — which happens, although it’s harder — we work within the constraints of what was already framed and roughed in. We’ll write a candid recommendation after the first site visit about what can still be done well, what can be done acceptably, and what should be deferred to a future refresh.

Closing.

The right way to specify Crestron in the architectural drawing set is the same as the right way to specify any other fixture: in the drawings, by an engineer who reads architectural drawings, in coordination with the trades that read them. The wrong way — deferring to the AV integrator’s submittal after CD — produces the residences where the technology feels grafted onto a finished house rather than designed into one.

If you’re an architect or design team working through this on a current project, we’re glad to read your drawings and write a short recommendation. Most engagements that start that way settle into something more permanent over the life of the residence; that’s the work this firm exists to do.
