Discovery
We start with a conversation about the house, its stage and your priorities, then define where EHT can help.
What you get
- A clear starting scope for the home
- An honest answer on fit and next steps
One home. Systems working together.
We design and deliver integrated home systems, from electrical infrastructure, climate and energy to lighting, security and smart home automation.
From focused smart home upgrades to complete whole-home integration.
Power, climate, energy, lighting and smart home technology. Planned together. Built to work as one.

The home follows your day.
Morning
Shades rise with the light, and the house is already warm.
Evening
Light turns warm and low, shades settle partway. One touch at the door.
Movie
Lights fade, shades close, the screen and sound are ready. Nothing to find in an app.
Away
One tap as you leave: lights off, shades closed, climate eased back, the house in view from anywhere.
Illustrative. What each moment does is designed with you, for your home and your systems.
The whole home, made to measure.every system tailored, never from a template.

Discuss your projectProven technology. Selected for your home.
We select established platforms and equipment to match your home, priorities and project requirements. Trademarks belong to their owners; listing a platform does not imply a partnership.
However you ask, the house answers as one.
Control your home through wall keypads, touchscreens, your phone or voice. Everyday routines run automatically, with manual control always within reach.
- Wall controlsFamiliar and always within reach.
- Phone & touchscreensYour home at a glance.
- Voice controlA simple way to ask.

AvailabilityAvailable controls and integrations depend on the selected systems. You choose what connected assistants can access.
Before the walls close, and long after you move in.
The best time to plan a home’s technology is while it is still on paper. We stay with it through construction, handover and the years that follow.
Design
Technology Planning
We plan the systems before the walls close: equipment, wiring, network and controls, with interfaces defined for each trade.
What you get
- An integration concept and system list
- Locations and requirements for each trade
- A written scope and acceptance criteria
Construction
Integration
Licensed trades install the equipment. We coordinate system interfaces, connect the agreed technology and configure controls, scenes and automations.
What you get
- Connected systems with one control logic
- Controls, scenes and automations set to your routines
Construction
Commissioning
We test each agreed function in the finished home, including what happens when a device or network connection fails.
What you get
- Checks against the agreed scope
- Documented behavior when a system is unavailable
Move-in
Handover
We hand over system documentation and owner access, then walk you through the controls and everyday routines in the home.
What you get
- System documentation and owner access
- A hands-on walkthrough of everyday controls
Living
Ongoing Support
After move-in, we diagnose issues remotely, make agreed updates and adapt the system as your needs change. Support terms are set up front.
What you get
- Remote diagnostics and agreed updates
- Changes and additions as your needs evolve
- Coordination with trades when a visit is needed
Licensed electricians, HVAC, plumbing and low-voltage specialists install the equipment. EHT plans and coordinates the agreed technology scope, then integrates, configures, commissions and documents it.
Designed early. Built right. Supported after.
Drawn in, not bolted on.
We work alongside your architect, designer and builder to plan the home’s infrastructure and technology together, before construction decisions become costly changes.
Swipe to see the whole house.
Fewer surprises during construction. A home that works together at handover.
Bring us in earlyOur integration documents complement, and never replace, licensed engineering and electrical drawings.
Built to be lived with.
Thoughtful technology should make your home easier to live in, every day.
-
Simple everyday control
Familiar switches and clear controls for everyone in the home. Your phone is an option, not a requirement.
-
Resilience by design
Essential functions retain independent controls, with fallback behavior planned for network or integration failures.
-
Tested as a whole
We test individual systems and how they work together against the agreed requirements before handover.
-
Ready for the years ahead
Documented systems, owner access and a clear maintenance plan make future service and upgrades easier.
A real home. A working laboratory.
We use our own home to test equipment, refine automation and understand how systems perform together in everyday life. Our experience developing control software helps us evaluate integrations and build reliable solutions using established platforms.
- Compatibility
- Everyday comfort
- Reliability
Grounded in how houses get built.
Led by Pavel Dertyshnikov, EHT brings together residential construction experience, systems integration and software expertise. We plan and deliver each project with specialist trade partners, coordinating the work from design through installation and handover.
