Enjoy all the benefits of Passivhaus with the speed and quality of modular construction

Learn more about the benefits of Passivhaus and our certified build system. With all these advantages, it’s astonishing that anyone builds any other way. The energy efficiency alone is remarkable, but that’s really just the start.

Full design flexibility and futureproofing

The Beattie Passive system has no restrictions on design. Our architectural design team will transform any shape or style of architectural drawing into a 3D model, using the latest BIM software, to deliver a custom-made package that incorporates all the benefits of our build system.

The Beattie Passive build system also has no limitations in terms of external finishes, so each Beattie Passive home can be as unique as its owner.

Passivhaus has many benefits. One of the most compelling is its flexibility. There are many myths regarding Passivhaus living that simply aren’t true, such as not being able to open windows or not being able to have a wood burning stove. Of course, you can open windows and you can have a wood burning stove if you want one. However, you’ll probably find the air quality and ambient temperature so comfortable, that you won’t feel the need.

Passivhaus means no more chilly draughts in winter or overheating in summer. The system responds positively to a changing climate (overheating and cooling) due to the innovative design and the lightweight structure.

Our homes can be modified and altered over their lifetime because they have minimal internal structural walls. This cuts down on house adaptation costs and providing design flexibility. All Beattie Passive houses have a continuous service void around all floors, walls, ceilings and roofs, allowing for ease of maintenance and alteration – and easy access to all services.

With Beattie Passive, you receive a high quality building that exceeds Passivhaus standards every time. Robust inspection of key build elements and testing ensures every building is built as designed.

Environmental, financial, health and wellbeing benefits

The cheapest and most renewable energy will always be the energy you don’t use. By adding MVHR and triple-glazed windows to a Beattie Passive structure, you can significantly reduce heating demand.

We always adopt a ‘fabric first’ approach. A traditional heating system is not require, due to the high performance of the structural thermal envelope and the heat recovery in the ventilation system. From here, it’s a relatively straightforward task to add a source of renewable energy and achieve net zero.

Beattie Passive is raising the benchmark for quality and standards, exceeding current building regulations.

Existing Building Regulations | Beattie Passive
Fire Safety: 1 hour | 4 hour fire protection between dwellings
Sound-proofing: 45db | 54db sound between dwellings
Thermal Efficiency: U-values: 0.18 | 0.11 and below
Airtightness: 8 | 0.06 and below

  • Fire safety – Beattie Passive provides you with 4 hours fire protection to party wall as standard.
  • Sound – Beattie Passive delivers 54db, which is considerably better than building regulations. This results in a dramatic reduction in sound between dwellings and external noise, such as busy roads or flight paths.
  • Thermal Efficiency – Beattie Passive can achieve thermal efficiency of 0.11 and below. This means that the building loses significantly less heat than a traditional construction.
  • Airtightness – Our build system achieves results below 0.06 and this means that there is minimal heat loss through convection. Essentially, you’re retaining heat within the building, lowering the heating demand.

Flood protection is incorporated into all Beattie Passive houses as standard. You can rest assured that our homes are tanked to protect you from flood water.

You can’t see radon gas and you can’t smell it or taste it. But it may be a problem in your home. Radon is a naturally occurring radioactive gas that is present to some extent in all rocks beneath foundations. Each year, there are approximately 1,100 deaths in the UK as a result of lung cancer linked to radon exposure in the home.

At Beattie Passive, we fit radon protection as standard, regardless of the readings in your area.

The UK has a legally-binding commitment to reach net zero by 2050. The housing sector emits an enormous amount of carbon and UK homes are notoriously inefficient.

The Passivhaus standard is a proven route to net zero for new builds while EnerPHit provides a rigorous framework for retrofitting existing buildings. The energy efficiency and environmental benefits are undeniable.

Use the Beattie Passive structure, MVHR and photovoltaic cells together to reduce CO2 emissions by up to 100%.

Beattie Passive believes that a building should offer its occupants more than just a ‘roof over their heads’ – it should also protect them from external factors which may adversely affect their wellbeing and actively promote good health.

A Passivhaus encourages more fresh air to circulate than traditional construction techniques. With a Mechanical Ventilation and Heat Recovery (MVHR) system supplying a continuous flow of pre-warmed fresh air, your house will be healthy and free of humidity (and any associated problems, such as mould) as well as airborne pollutants.

A continuous supply of fresh, filtered air reduces health issues:

  • Reduction in respiratory illnesses (e.g. asthma)
  • Protection from pollutants: mould, CO2, smoke, radon, humidity and pollen
  • Faster recovery from illness

We make Passivhaus more accessible, so everyone can take advantage of the energy efficiency, comfort and carbon-saving benefits. As the first UK company to have a complete, certified build system, Beattie Passive can reduce the build cost and simplify the process.

Construction benefits

Modular housing offers a host of benefits compared to traditional methods of construction.

  • Speed: Modular construction can be completed up to 50% faster than traditional construction methods. This is because the modules are prefabricated in a factory setting, which reduces the time spent on site.
  • Cost efficiency: Modular construction can save up to 20% on construction costs, as it reduces the need for on-site labour and reduces material waste.
  • Quality control: Modular construction takes place in a controlled factory setting, which allows for better quality control and a higher level of precision in the construction process.
  • Sustainability: Modular construction can be more environmentally friendly due to reduced material waste and the ability to reuse modules in future projects.
  • Safety: Modular construction has a lower risk of on-site accidents, as it takes place in a controlled factory setting.
  • Flexibility: Modular construction allows for flexibility in design and the ability to easily add or remove modules as needed.
  • Adaptability: Modular construction allows for buildings to be easily adapted for different uses or to accommodate changes in occupancy.

Many buildings are ‘closed’ when structural inspections take place. We ensure our houses are inspected at the right time. This gives you complete peace of mind that your building has been built correctly.

  • Upon completion of the structural build, all joints and fixings are open for inspection by Building Control, Warranty Provider, and an independent Structural Engineer.
  • Building Control, Warranty Provider and independent Structural Engineers can study 3D BIM models before arrival on site – speeding up the process and making everything more efficient.

Bespoke 3D modelling means all materials can be measured to within a single millimetre. This reduces wastage and any over-ordering of materials.

We use Just in Time (JIT) production methods to reduce inventory costs and improve our quality processes. JIT also reduces lead times, allowing us to quickly respond to customer demand and refine our production processes.

In tandem with 3D modelling, JIT manufacturing minimises the production of excess or unnecessary inventory, reducing waste and lowering costs. All these benefits improve turnaround times, leading to higher levels of customer satisfaction.

We’re passionate about developing skills in the construction industry. Our approach creates community and education-led project opportunities that give local young or unemployed people the chance to retrain and benefit, both financially and socially, from a return to the workplace.

Our build system is an easy to assemble frame-link build system. It can be built by semi-skilled labour.

We source materials from fully certified supply chains (A+ rated in the BRE Green Guide).
