Mumbai & Hong Kong · Interior design & automation
Ambient Form Studio is an interior design and automation studio working across Mumbai and Hong Kong. From a blank shell to a finished home — or a retrofit that barely touches a wall — we plan, install and tune lighting, climate, security, cinema and the devices that were never smart to begin with, as one system.
Live demo — Floor plan
Tap a marker and the room responds — lights, AC, blinds, awning, projector, lock. The same plan can live on a wall tablet in the hallway, so the house is legible at a glance, not buried in a list of entities.
A representative 2BHK layout — not a scan of this home. One plan for the client, the site team and the wall tablet. Rooms, devices and scenes stay in the same language.
Ask by voiceLive demo — Voice
Pre-programmed examples, not a live language model. The real assistant runs locally on the hub, so the same request still works when the internet doesn’t.
Local wake word, speech-to-text and text-to-speech — no audio leaves the house. Pick a request to hear a sample.
Local PocketTTS voice · sample. The live hub can clone any voice you have the rights to — no cloud round-trip.
“Close the awning.”
Done. Awning closed. Rain is twenty minutes out, buddy.
Most of the stack runs on Home Assistant. Open source, on a hub inside the home — local automations, local voice and local AI, with the cloud optional.
The brief
The best technology in a room is the technology you don’t see.
No visible boxes. No five-app chaos. No rented brain in a data centre. Just a home that responds — and interiors that stay exactly as designed.
01 — Every stage
Most automation firms only work at first fix. We start where you are: lead the whole interior, join drawings that already exist, or retrofit a finished home with almost no visible change.
Empty shell, new build or a full redo. We can lead the interior — space planning, materials, lighting and joinery — with automation designed into the same drawings.
You already have a plan, a designer or a contractor. We plug into it, coordinate first fix, and keep the technology invisible.
The home is finished and you’d rather not open a wall. IR, RF, relays and battery sensors bring existing devices into one system — reversible and renter-friendly.
One studio from concept to commissioning. The scope changes; the standard doesn’t. Not sure which stage you’re in? Send a floor plan and a photo — we’ll tell you.
The automation ladder
Most “smart homes” stop at remote control: an app that replaces a switch. The useful jump is when the house reacts to presence, light, time and context — without you opening anything.
One app per brand. You still do the thinking. Fine as a start; not a system.
One app, a few routines, sunrise and sunset. Less tapping — but the house still waits for a trigger.
Presence, light, weather and context. You stop touching switches. The room does the work.
An agent on the hub can turn a plain-language request into a new automation — locally, without a ticket.
We allow anything. We’re not loyal to a brand — we make the brands work together.
In practice Desk presence → monitor off · room empty → lights off · window open → AC off · rain due → awning in · sunrise → shades open.
The market
The short version: the three ways a Mumbai 3BHK gets automated, what each one costs, and where our layer fits. The full landscape and sources are at the bottom.
₹15–30 lakhCrestron / Lutron · 3BHK
Best if finish is everything and you want one firm to call.
₹1–2.4 lakhfor a 3BHK
Best if you enjoy tinkering and want to start small.
₹4.5–5.5 lakhfor a 3BHK
Best if you want it to work, stay open and be yours.
Why us, in one line: the same rooms and scenes for about a third of a premium quote — without five apps, a dealer holding the file, or a subscription for every device.
One local hub, one app, any brand that speaks a protocol, and a retrofit that doesn’t open walls by default. Start at ₹2 lakh for lights and presence; a whole home from ₹5 lakh. The device schedule, network map and project file are handed over.
These are capex bands, not five-year costs. The premium column also carries an 8–15% annual contract; the DIY column carries subscriptions and your weekends. The calculator below adds both. At ₹5 lakh we sit at the Control4 floor — with an open system.
A Basalte keypad is ₹35,000–90,000 before it is wired. Our whole-home layer starts at ₹5 lakh. The money goes to devices and design, not a licence.
Lights, AC, shades, door and camera in one place, on a hub in the house. It works offline, and the family can use it without a manual.
No mandatory AMC, no dealer holding the file, no per-device cloud plan. If you sell the flat, the system goes with it.
3 bedrooms · 18 lighting circuits
A circuit is a switched lighting group, not a device. Two to four bedrooms plus living, dining, kitchen, balconies and passages usually lands between 14 and 24.
Indicative capex₹15–27 lakh
Running: ₹2.6 lakh a year
Five-year cost ₹34 lakh
Indicative capex₹1.4–2.6 lakh
Running: ₹30,000 a year
Five-year cost ₹3.5 lakh
Indicative capex₹4.3–5.5 lakh
Running: ₹29,000 a year
Five-year cost ₹6.4 lakh
Indicative only. The model assumes a 3BHK-scale scope, a mix of lighting, climate, shade, entry and media, and ₹1,800–3,000 per circuit for hardware. Premium running cost is 12% of capex a year; DIY is ₹24,000 a year of apps and replacements; ours is an optional 6% support plan. No GST. A walkthrough replaces every number.
Anything with a feed
Metro timetables, traffic, flights, weather, energy prices — and Swiggy / Zomato delivery ETAs, where your account or a partner API makes them available. Most automation stops at the device. We connect the live data to the home.
The metro is already telling you when to leave
A sensor knows you’re home. The published timetable and live disruption feed know when the next train is. Walking time and the platform finish the maths. The result is a light at the entrance that says leave now, wait, or take the next one — not another app to check.
If the train is delayed, the light waits. If the next one is too tight, it tells you. If you’re not home, it doesn’t bother.
If it has an API, a feed, a sensor, or IR/RF, it’s usually a candidate. This is the layer most automation companies never reach.
More than lights
Each one is a live signal, a rule and a useful output. No dashboard required.
Timetable + live disruption + walk time + presence. Entrance light says leave, wait, or next train.
Swiggy / Zomato ETA on a small kitchen display; porch light turns amber under five minutes.
Walk away from the computer: monitor off, desk light off, AC back. Walk back: everything returns.
A window sensor cuts the AC — no remote, no reminder, no wasted afternoon.
Rain feed or local sensor closes the awning and shades before the balcony gets wet.
Shades open at actual sunrise — a different time every day — or hold blackout if you’re still asleep.
Live travel time updates; the house tells you when to leave, not just what the traffic app says.
When the tariff drops, the house runs the dishwasher, water heater or EV charger — automatically.
Feed the cat at 7:00 and 18:00, portion-controlled. Skip if already fed; ping you if the bowl is empty.
The difference
Typical patterns, not a brand-by-brand audit. Ambient Form Studio is vendor-neutral and local-first.

02 — For designers & architects
You shouldn’t have to become an integrator to deliver a smart home. We join early, read your drawings, and carry automation from first sketch to final scene — so it disappears into your design. We think in plans and materials as much as protocols. If a client wants one studio to lead both the interior and the technology, we can do that too.
03 — Capabilities
One studio for the parts of a home that need to talk to each other — specified, integrated and tuned as one system instead of a pile of gadgets.
Layer ambient, task and accent light. One tap for dinner, a film, or “away” — with the right dimming curve, not a harsh on-off click.
ACs, fans and sensors working together — room by room, schedule by schedule, and off when the last person leaves.
Doorbell, cameras, locks and alerts in one view — with local AI captions that say what happened, not just that motion was detected.
Projector, screen, soundbar and shades fall into place from one button — or one sentence — without four remotes on the coffee table.
Morning light without the alarm, blinds down before the afternoon glare, the awning in before monsoon rain.
See what’s drawing power today, spot the AC left on in an empty room, and automate the offenders off.
A wake word and commands processed on the hub inside the house — not by a speaker company’s data centre.
Wi-Fi that reaches the last bedroom, a rack a technician can service, and screens that make sense to the people using them.
ACs, awnings, projectors, curtains and audio brought into the system through IR, RF, relays and bridges. If it has a remote, it can usually join.
Battery health, device health and camera clip retention are handled quietly in the background.
04 — Made to measure
“Can it close the awning when the sun hits my desk?” Yes. “Can the shades open at sunrise, even though it’s a different time each day?” Yes. “Can I add a new rule after handover?” Yes — tell the local agent. These are examples, not a fixed menu.
The awning closes when the sun hits the desk or the balcony heats up, and reopens when it moves. No remote, no getting up, no lost afternoon.
Shades open at sunrise — a different time every day — or at a fixed time you choose. Blackout stays until you’re actually ready to get up.
Describe it to the local AI agent in plain language and it can add the automation. No call-out. For the fiddly or physical bits, we’re still here.
Meet the local agentThese are starting points, not a catalogue. If you can describe it — the sun, a time, a sensor, a person, a phrase — it can usually be built. Fully custom, down to the individual room. The list is effectively endless.
05 — Retrofit
Most homes already have good hardware — it’s just not connected. We use IR, RF, relays, bridges and sensors to bring existing devices into the same system. No rip-and-replace. No second app. No new wall clutter.
“A rooftop awning with no app, no API and no position feedback — now closes before rain and reports its state.”
The kind of problem we likeWe start with what’s there. Replacement is a last resort, not the business model.
Most of the system needs no drilling: plug-in lighting, IR climate control, battery sensors, a camera on a shelf. Move-out is an afternoon, not a renovation.
In-wall switches, motorised tracks, concealed sensors and a wall dashboard — specified before first fix, so nothing gets chased into a finished wall later.
06 — Spaces
Six ordinary moments from a well-run home. The technology is in the layer behind them: light, shade, air, sound and the quiet certainty that the door is locked.
Automation, in motion
This is the plan demo running: lights, AC, projector, awning and lock changing together. The interactive version is further down.
Try the plan yourself

07 — One interface
No five-app handover. Lighting, climate, security, media and energy live in one interface — the same one on your client’s phone, the wall tablet and the family’s devices.
Handover includes labelled devices, a scene list, a one-page guide and a support number your client can actually reach.
Courier, blue jacket. Left a parcel at the door. Local AI description, no cloud.
08 — Local AI
High-end clients ask where their data goes. With Ambient Form Studio, the answer is simple: it stays in the house. Camera descriptions, voice recognition and the language model run on a hub inside the apartment — not on someone else’s server.
No round trip to a data centre
A local vision model turns a blurry snapshot into “a courier in a blue jacket left a parcel” — and keeps the history on your hub.
Wake word, speech-to-text and text-to-speech all run on the hardware in the house. No audio sent to a speaker company.
Lights, AC, locks and scenes keep running if the internet drops. Remote access and alerts need the internet; the house doesn’t.
Open-source Home Assistant at the core. No black box, no mandatory cloud subscription to keep the basics alive.
After handover
We can leave a local AI agent on the hub. Describe the automation in plain language — “when the afternoon sun hits the balcony, close the awning” — and it can add it to the system. No cloud account, no ticket, no waiting.
When something physical needs a visit — a motor, a lock, a sensor, a failed device — we’re still here for on-site troubleshooting, repair and recommissioning. The system is yours; we’re the backup.
Ask about handover“When the afternoon sun hits the balcony, close the awning. Open it again at sunset.”
Streaming services like Spotify and Netflix still use the internet. We’re talking about control, cameras and voice — the parts that should never need a data centre.
09 — The proof
A live installation, not a render. Every automation on this page has been lived with.
It’s the stack running a real home today — 85 automations, 12 dashboards, 3 camera feeds and one app. Built, broken, fixed and lived with.
The numbers are from the live system — awnings, projectors and older audio, all running from one app.
10 — Process
We work alongside your studio and your site team, not around them. The earlier we’re involved, the less visible the technology — and the fewer surprises at handover.
Floor plan, elevations, device list, client lifestyle. We flag what’s possible — and what isn’t worth it.
45 minutesDevice schedule, scene list, network and power notes, retrofit map and a budget you can build from.
3–5 daysWe work with your electrician, carpenter and vendors. Ceiling, joinery and cable routes sorted before they close.
As neededScenes tuned on site, labels, a one-page client guide, and a two-week snag window.
1–3 daysComing in after first fix? We can retrofit — it just means a few more visible decisions.
11 — Indicative pricing
Indicative launch pricing for Mumbai and Hong Kong. Other locations by arrangement — start with a video call, then a walkthrough or site visit once the scope is clear.
Start with the layer you feel every day: light that follows the room and the people in it.
The full layer: light, climate, shade, security, media and voice, running as one system.
For a new home or full redo: the interior and the technology designed together, from first sketch to handover.
Home visits, site supervision and commissioning — our home base.
Design and retrofit projects; local labour and electrical costs reflected in pricing.
Remote-first. A video call to understand the home, then a site visit or local partner if needed.
Book a video callIndicative launch pricing for Mumbai, exclusive of GST. Final scope and quote after a walkthrough; hardware and site work line-itemed before you approve. Studios: see the engagement models for trade terms.
12 — Engagement
Fixed-scope fees, not hourly surprises. Every engagement starts with a 20-minute call, a floor plan and an honest view of what your project needs.
For studios that need the plan, not the install.
For new homes and full renovations where we lead the design.
For practices with a pipeline of projects.
Fees depend on scope, site access and the number of systems. We confirm everything in writing before work starts. Blueprint fees are credited against commissioning if we take the project through to handover.
Questions
If yours isn’t here, send a message — we answer within one working day.
Yes. We can produce drawings, schedules and client documentation under your studio’s name and stay invisible on site — or be introduced as your automation partner. Either way, the client relationship stays yours.
Yes — that’s usually the best setup. We define the automation scope and the interfaces, then coordinate with your contractor on power, network, ceiling and joinery requirements. We’re happy to work to their programme.
A floor plan, a brief on how the client lives, any device list they already have, and a few site photos if available. If drawings aren’t ready, a rough plan and a 20-minute call is enough to start.
That’s our default. ACs, awnings, projectors, curtains, lamps and older audio can often be brought in through IR, RF, relays and bridges. We audit what’s there first and only recommend replacement when the existing device genuinely can’t be integrated.
We’re vendor-neutral. We can supply and commission, or specify for your vendor to supply. Hardware is billed at actuals with your approval, and we don’t design around a single brand’s catalogue.
Concept or design development is ideal — that’s when power, network, ceiling and joinery decisions are still open. We can also retrofit at the end of a project; it just means a few more visible compromises.
A fixed project fee based on scope, not hourly billing. The blueprint is a standalone deliverable; if we take the project through commissioning, that fee is credited. Studio partners get trade rates and priority slots. See engagement models.
Camera, voice and automation data stay on a hub inside the home by default. There is no mandatory cloud subscription and no vendor access to the client’s footage unless they explicitly grant it for support. The full picture is in our privacy note.
Mumbai and Hong Kong are our home markets. Elsewhere, we start with a video call, then decide whether a site visit, a local partner, or both make sense. Travel and site supervision are quoted separately.
Most of it runs on Home Assistant on a hub inside the home — open source, local automations, local voice and local AI. The cloud is optional, not the foundation.
For serious enquiries, yes — subject to the client’s permission. We can also demonstrate the system and the app over a video call, which is usually faster.

Research & sources
The full landscape, the method and every source, read on 6 November 2026. Skip it if the short version was enough.
The finished room: bespoke keypads, lighting scenes, AV, blinds and security from one catalogue, installed and warranted by a dealer. This is the benchmark for how a smart home should feel.
Names you’ll meet: Crestron, Lutron, Basalte, Savant. In Mumbai, Trescent Lifestyles has built a business on this model since 2006; the lowest band on its enquiry form is ₹25–50 lakh.
An open bus with a luxury surface. KNX is a real standard, not a proprietary one, and a good integrator can mix Basalte, ABB and CORE keypads in one project. That is a genuine advantage over Crestron and Control4.
Names you’ll meet: Basalte, ABB, CORE, Gira, Jung, MDT, Theben; KNX-certified integrators in Mumbai and Pune.
Control4 is a dealer-installed system with a curated catalogue. AHA Smart Homes publishes a ₹5 lakh complete-3BHK benchmark from two Mumbai experience centres. If you want one brand, one showroom and one warranty at our price, this is the honest alternative.
Names you’ll meet: Control4, AHA Smart Homes; builder packages that arrive with the flat and end at handover.
Aqara sensors, a couple of smart switches, an IR blaster, a Hue bridge and the app that came with each. Cheap to start, genuinely useful in a rental, and entirely yours — until something stops working.
Names you’ll meet: Aqara, Xiaomi, Philips Hue, Wiz, SwitchBot, Apple Home, Google Home, Alexa — and a different app for each.
One layer over whatever hardware is already there. Not a catalogue and not a single app: a local hub that speaks the protocols, one interface, and a studio that designs the interior and the automation together. At ₹5 lakh we are 37–75% below the published KNX band and 67–83% below Crestron, without giving up the functions that matter.
What we don’t sell: a brand, a licence, a five-year lock-in, or a showroom you pay for.
Figures are indicative, not a quote. A firm is named only where it has published a price.
