Laoliu Healthy Mansion | Healthy Villas & Large Flats

What We Deliver

We don't sell materials or equipment. We deliver amansion that breathes

A mansion that breathes, a healthy family. For you and your family, it comes down to these four things.

Care for You

Real care starts with adding no burden. The wall and ceiling systems we deliver use inorganic substrates and no urea-formaldehyde adhesives, and test reports are provided when materials arrive on site.

Nourish You

Temperature, humidity, air, and light are all taken care of, so health becomes the default state of living rather than something you have to maintain deliberately.

Protect You

Whole-home sensing and automatic judgment keep falls, intrusion, gas leaks, and water leaks outside the door, and notify the family the moment anything happens.

Fulfill You

Quiet, focused spaces that restore the mind—helping you become your best, and every member of your family too.

See the Problem First

When you renovate, will yougamble with your family's health?？

Health is usually decided by what you cannot see. In ordinary renovation, these four risks are almost impossible to avoid.

Formaldehyde

Formaldehyde, invisible

It comes mainly from engineered wood panels and adhesives, can keep releasing for 3–15 years, and ventilation only lowers the concentration—it cannot remove the source.

Mold

Mold, hidden in the walls

Condensation, seepage, and an organic base inside the wall create the conditions for mold to grow; by the time you smell it, it has usually spread across the surface.

Stuffy

High CO₂ leaves you stuffy

Close the windows and it gets stuffy. Recirculating purifiers only filter the same indoor air and cannot lower CO₂ levels.

Noise

Noise you cannot escape

Street traffic, equipment, neighbors—open a window and it all comes in; close it and the air goes stale, and you sleep poorly at night.

5×

The larger the area, the more pollution sources accumulateEstimated by painted and panel surface area, a 500㎡ villa uses roughly five times the volume of major pollution-source materials as a 100㎡ home. More material means a greater total release, and dilution by ventilation becomes harder.

Six Constants

Six things “just right,” each with its ownexplicit figure

No guesswork. Every metric is written into the contract and judged by third-party CMA re-testing.

01 · Constant Temperature

22–24℃

Whole-home temperature difference ≤ 2℃

Not dry in winter, not stuffy in summer, and the floor is warm underfoot.

02 · Constant Humidity

Around 50%

Humidity 50±5%, 60–70% in the wine cellar

No damp, no mold, and skin that doesn't feel tight.

03 · Constant Oxygen

Air that stays fresh

CO₂ when occupied ≤ 800ppm

no more than 500ppm above outdoor levels, so even a full house feels fresh

04 · Constant Cleanliness

Filtered clean

Formaldehyde ≤ 0.06 mg/m³, with PM2.5 and odors filtered out

Stricter than the GB/T 18883 limits; delivery is judged by the test report.

05 · Constant Quiet

Quiet for deep sleep

Indoor noise at night ≤ 30 dB(A)

Equipment is nearly silent, so you sleep deeply through the night.

06 · Constant Water Quality

Drinking water from the tap

drinking water TDS ≤ 10

Straight from the tap, with no more bottled water to carry.

Note: the figures above are delivery targets. Actual results are determined by third-party CMA re-testing under GB/T 18883-2022, and the test conditions and judgment methods are set out in the contract annex.

Standard numbers and test methods for the six metrics

Our Approach

This is not a fit-out. It is buildinga living, breathing body

Like a person, it has a body, it breathes, it thinks, and it protects. Six parts, each with its own role.

Skeleton and Skin

Designed to passive house envelope and airtightness standards, with inorganic materials and thermal bridges resolved—first the house is given a body that carries no burden.

Lungs

Full fresh air, no mixing: stale air out, new air in.

Brain and Nerves

A whole-home smart controller plus a sensor network that senses, decides, and coordinates everything together.

Immune System

Filtration, slight positive pressure, haze and odor removal, plus layered security keep risk outside the door.

Metabolism and Nourishment

Constant temperature and humidity, drinking water on tap—the family's day is quietly cared for.

Soul

A space of your own—meditation room, painting studio, study, workshop—calm and restorative.

Only when the body itself adds no burden do breathing, protection, and nourishment mean anything.

Core Technologies

Four systems that make the houseone whole

Not a stack of equipment, but a house that senses and adjusts on its own; all you need to do is live in it.

Section through the Smart Thermal-Storage Wall

01 · Smart Thermal-Storage Wall

Dressing the house in a coat that holds its temperature

Walls are no longer just partitions. They store thermal energy, they sense, and they become the “skin of the house.”

A galvanized steel stud frame, with weld-free clips and no OSB backing.
Built into the wall in one pass: lighting drivers, wireless network, power cabling, and whole-home fiber are all embedded, with not a single exposed wire.
Inorganic decorative facing: wood grain, stone, solid color, or texture, in any finish you choose—and no organic nutrients for mold to grow on.
Real-time feedbackWall temperature and humidity report to the mansion controller, keeping every adjustment accurate.

02 · Full Fresh-Air Five-Constant

Good lungs mean every breath is outdoor-fresh air

Full fresh air with no mixing: outdoor air is filtered, tempered, and humidified or dehumidified before it enters the room, then stale air is exhausted outdoors.

Whole-homeslight positive pressure, so dirty air, moisture, insects, and odors cannot seep in through the gaps.
Stable humidity 50±5%, and thermal bridges are treated so no condensation forms, leaving mold without conditions to grow.

Quiet zones ≥2 air changes/h Active zones ≥1.5 air changes/h Bedroom fresh air 50–100m³/h Unoccupied 0.5 air changes/h

The Essential Difference Between Full Fresh Air and Conventional Fresh Air

03 · Brain and Nerves

The controller is the brain, and it holds the line even offline

The whole-home smart controller senses, decides, and coordinates; the wall panel is simply the window through which you speak to your home. Keeping decisions on the local device is what lets the system keep working when the network goes down.

The whole-home smart controlleris the real brain; the control panel shows status and takes commands, but it does not think.
Whole-home fiber network, with no traditional network cable—every network link in the house runs on fiber.
Core HVAC and security control runs on the local device, with no dependence on the cloud; remote viewing and voice assistant features require a network connection.

What still works when the network goes down

04 · Immune System

Keeping risk outside the door

We gave the house an immune system: layered protection whose core functions do not depend on the cloud.

Fall detection: millimeter-wave radar recognizes suspected fall postures and sends an alert. This is an assistive reminder, not a medical or emergency-response measure.
Intrusion prevention: smart locks plus door and window security send instant alerts on any anomaly.
Gas protection: smoke and gas leak detection triggers exhaust ventilation and sends an alert.
Leak and fault protection: leaks shut the valve immediately, and faults in the power and smart panels raise local warnings.

The layered logic and limits of security

Why Trust Us

Multiple parties drawing separately, versusone mind drawing the whole—the difference

Separate drawings from multiple parties (subcontracted model)

Each party draws its own scope, so interfaces clash easily
Waiting on site for drawings, repeated rework, ceilings too shallow, services colliding
Responsibility is fragmented, and problems bounce between parties
No one is accountable for the indoor environment as a whole

Integrated delivery (us)

Plumbing, electrical, MEP and semi-fitted construction drawings all issued by one party
Coordinated at the drawing stage, so interfaces do not clash
One party accountable end to end, with traceable progress and responsibility
Accountable for the overall result in temperature, humidity, air, and noise

Parameter-based delivery

Target values and pass criteria for temperature, humidity, CO₂, noise, and formaldehyde are all written into the contract.

Delivery against operating metrics

Not just at handover: temperature, humidity, air, and energy data remain verifiable through long-term operation.

Transparent throughout

Every step and every milestone can be seen, checked, and traced.

Backed by contract

If something goes wrong, the contract defines responsibility and the process; nothing rests on verbal promises.

① Delivery standard

Before handover, a CMA-accredited body re-tests under GB/T 18883-2022; where results fall short of the contracted values, the agreed remediation is carried out and the tests are repeated.

② Mold liability

Where the cause falls within our scope of delivery and the system has operated as specified, mold caused by the system is handled under the contract.

③ Warranty commitment

A 3-year system warranty; its scope, response times, and exclusions are set out in the contract annex.

You don't need to “trust us.” You only need to “verify the result.”See exactly what the contract commits to →
