The Approach

Technology that
disappears.

A home this considered should never feel "programmed." Control should be where the hand expects it, behaviour should follow the people in the room, and every floor should stand on its own.

Tactile-first Presence-aware Floor-resilient Daylight-aware
01

Tactile at the threshold

Crestron Horizon keypads at every entrance — engraved, back-lit, muscle-memory. The screen is the second move, never the first.

02

The house knows who & where

Named occupant profiles carry personal presets; BLE beacons resolve which room a person — or a request — is in.

03

Distributed by floor

A DB in every room on Cresnet, a processor per floor. One device fails, the rest of the house carries on.

04

Aware of light & air

A terrace photosensor reads the real sky; climate, dehumidification and shades respond to conditions, not clocks.

03 — Scope
System Architecture

A DB in every room. A processor on every floor.

A fully distributed topology. Each room is self-contained; each floor is independent; the house is tied together over one IP backbone — so a fault stays local and never takes the home dark.

Tier 1 · Inside the Room DB

A board of
Crestron DIN modules.

Each room's distribution board carries a compact stack of DIN-rail Crestron modules — dimming, switching, climate and power — all on one Cresnet pair to the floor. Keypads home to this DB on Cresnet; touch screens run to the floor network switch on the fibre backbone. This is the ideal design — the final DB is fixed against each room’s equipment schedule.

Tier 1 · A Typical Room — Wiring & Controls

One room, wired two ways

A typical bedroom, top-down. The Room DB feeds keypads over Cresnet, lighting over TRIAC, curtains & dehumidifier over RS-485, and the TSAT drives the VAV. Switch the control layout and click any keypad to see its engraving.

Tier 2 · A Floor in Depth — Third Level

The master floor, zoned & wired

A representative layout. Each room carries its own DB (●); all home onto the central floor DB & processor (●) over Cresnet. The same pattern repeats on every level.

Habitable Floors · Device Plan

Place the screens, count it live

An interactive layout for every habitable floor — pick a floor, drag any Crestron touch screen or keypad to another wall, add or remove devices, and the live quantity schedule (this floor + whole house) updates the moment you do.

The Subsystems

Six services, one fabric

Every controllable system in the house, normalised into one language — so a scene, a schedule, or a single keypad press can touch any of them together.

01

Lighting & Scenes

Circuit-level dimming and tunable scenes across every habitable room, façade & landscape.

Curtains & Shades

Motorised drapes & sheer pelmets on every elevation, scene-linked to light and time of day.

Climate — HVAC

Crestron TSAT thermostats driving the VAV air-conditioning per zone, with set-back schedules.

How You Touch It

Three surfaces, one behaviour

The hand reaches the keypad first; the screen is there when you want more; the phone follows you out of the house. All three speak to the same processors.

Personalisation

The house knows who you are

No generic "guest" mode. Each resident — and each staying guest — gets a named profile carrying their favourite channels, apps, scenes & comfort settings, ready the moment they enter a room.

Proximity & Service · BLE Beacons

Aware of who’s where

Under evaluation: low-energy Bluetooth beacons in each room. They let the house follow a person between rooms — and let a butler request resolve to the exact room it came from.

Proximity sensing

A beacon in every room DB. A phone or wearable resolves which room a resident is in — so lights, climate & favourites follow them, and scenes arm only where someone actually is.

Butler calling

From any keypad, screen or phone, order tea, coffee, a meal or snacks. The beacon stamps the request with its origin room and routes it to the on-duty staff station.

Terrace Photosensor · Daylight Harvesting

Lit by the real sky

One photosensor on the terrace reads true outdoor light. Interior electric lighting and shades trim continuously to hold a target ambience — saving energy and keeping rooms naturally lit.

High Low 6 AM Noon 8 PM

Outdoor daylight

Measured live by the terrace photosensor.

Electric light output

Dims as daylight rises — inverse to the sky.

Shade position

Modulates glare while preserving the view.

Constant ambience

Rooms hold a steady, natural light level all day.

A clear path to handover

Five phases, sequenced against the build. Wiring goes in with first-fix; programming and personalisation happen once rooms are weather-tight.

Phase 01

Design freeze & BOM

  • Confirm scope & subsystems
  • Lock control schedule
  • Crestron bill of materials
  • Head-end & rack design

First-fix wiring

  • Room DBs + Cresnet
  • Keypad & screen back-boxes
  • Floor processor positions
  • Photosensor & beacon cabling
Phase 03

Programming

  • Loads, scenes & schedules
  • HVAC, pool & dehumidifier
  • Touch-screen UI build
  • Keypad engraving sign-off
Phase 04

Commissioning

  • Profiles & presets
  • Daylight calibration
  • Butler & beacon trial
  • Scene tuning on site
Phase 05
