Choose Netzero Builders

Netzero Builders at Graven Hill.

Located in Bicester, Oxfordshire, Graven Hill is the largest self-build scheme in the UK offering many self-build opportunities and a fast-track planning application process.

It’s the perfect match: combine the advantages of building on a ready-made site with a built-in infrastructure with a stylish, energy-efficient timber-frame house.

You can also benefit from competitive and transparent pricing, a fast turn-key construction process, energy-saving technology, and experience that comes from building over 11,000 houses in Europe.

The specifications will far exceed what a builder is going to give you, because you get what you want, on a budget.

Our inclusive service and fixed price guarantee

Netzero Builder can build your house on a turn-key basis. This means we construct the complete outer structure for you, including the roof, roof drainage, external doors and windows.

We also do all the painting and decorating work, the floors are laid according to your choice of tile or carpet, and the bathrooms are equipped with sanitaryware and fittings.

This option also includes complete electrical and plumbing installations, a gas boiler and 120-litre hot water cylinder with plate radiators, mechanical ventilation with a heat recovery system.

For a reasonable surcharge, you are able to upgrade your home with Air or Ground Source Heat Pump and Underfloor heating system.

Netzero Builder’s houses are almost 100% airtight. We achieve this by using modern construction technology to ensure that heat is kept inside the house.

Every Netzero Builder house also features mechanical ventilation with a heat recovery system. This is extremely important in energy-efficient houses, as the continuous exchange of air provides a comfortable and pleasant atmosphere in the house at all times, and helps to reduce heating bills.

Netzero Builder houses have a B Energy Efficiency Rating which is a measure of its overall efficiency. The higher the rating, the more energy efficient the house is, and the lower the fuel bills are likely to be. In buying an environmentally-friendly Netzero Builder house, you can then benefit from much lower heating costs.

Here are some other benefits:

Save money

Your energy bills will drop, and you can also receive bonus payments for any surplus electricity that is fed back to the grid.

Low maintenance

Solar panels only need cleaned a couple of times a year and, with no moving parts, there is little wear and tear.

Clean Energy

The initial cost of installing solar panels easily pays for itselfin a few years, and it will increase the value of your house.

Renewable energy systems


If you’re building a Netzero house at Graven Hill you can benefit from a Solar Thermal System at a very special price.

Solar thermal panels can provide up to 60% of the energy required to heat water and support the heating system, so it’s easy to see what a fantastic investment they can be.

A solar thermal system comes as two or three high-performance flat collectors on the roof, which convert the sun’s rays into hot water.

As part of its pro-environmental policies, Netzero builders also uses the most up-to-date renewable energy systems such as heat pumps and photovoltaic panels.

5 ways to reduce the carbon footprint of a large building

5 ways to reduce the carbon footprint of a large building

What is a building’s carbon footprint? A building’s carbon footprint is the total amount of greenhouse gas emissions produced as a result of its construction, maintenance, and use, including emissions from energy use, waste, and embodied energy in building materials. It can also include emissions from transportation of people to and from the building. Measuring and reducing a building’s carbon footprint can help mitigate the impacts of climate change.|5 ways to reduce the carbon footprint of a large building.5 ways to reduce the carbon footprint of a large building.

5 ways to reduce the carbon footprint of a large building

  • Energy Efficiency: Upgrade lighting, HVAC and insulation to reduce energy consumption and reduce emissions from energy production.
  • Renewable Energy: Implement renewable energy systems such as solar panels, wind turbines, or geothermal systems to reduce reliance on fossil fuels.
  • Water Conservation: Install low-flow toilets, showerheads, and faucets, as well as utilize rainwater harvesting and greywater systems.
  • Green Transportation: Encourage alternative transportation methods such as cycling, public transportation, or car-sharing programs.
  • Sustainable Procurement: Purchase products made from sustainable materials and promote waste reduction and recycling programs.

How to reduce the environmental impact of a large building

  • Energy efficiency: Implement energy-saving measures such as insulation, efficient HVAC systems, and energy-efficient lighting and appliances.
  • Renewable energy: Install on-site renewable energy systems such as solar panels or wind turbines to generate clean energy and reduce the building’s reliance on fossil fuels.
  • Water conservation: Install low-flow fixtures and implement water-saving practices to reduce water usage.
  • Sustainable materials: Use sustainable and environmentally friendly building materials, such as bamboo, recycled materials, and low-VOC (volatile organic compounds) products.
  • Green roof and walls: Incorporate green roofs and walls to reduce the building’s heat island effect and improve air quality.
  • Transportation: Encourage the use of public transportation, carpooling, and biking by providing amenities such as bike storage and shower facilities.
  • Waste management: Implement a comprehensive waste management plan that includes recycling, composting, and reducing waste.
  • Building management: Implement a building management system to monitor and optimize the building’s energy and resource use.
2030 Climate Challenge

2030 Climate Challenge

The 2030 Climate Challenge is a global effort to reduce greenhouse gas emissions and limit global warming to 1.5 degrees Celsius above pre-industrial levels. It requires international cooperation and ambitious action from governments, businesses, and individuals to transition to low-carbon, climate-resilient societies and economies. Key solutions include:

  • Increasing the use of renewable energy sources
  • Improving energy efficiency
  • Decarbonizing transportation and industry
  • Protecting and restoring forests and other carbon sinks
  • Investing in climate adaptation and resilience measures.

Pre Fab homes

Pre Fab homes

Prefabricated homes, also known as prefab homes or simply prefabs, are homes that are built off-site in a factory and then assembled on-site.

They are constructed using a variety of materials and methods, including prefabricated wood, steel, and concrete. Prefab homes can be built quickly and efficiently, and they can also be customized to meet specific design and functionality needs.

They are often less expensive than traditionally built homes, and they are also more environmentally friendly as they use less materials and they are built in a controlled factory environment. Some of the advantages of prefab homes are faster construction times, lower costs, and increased energy efficiency.

However, it’s important to note that prefab homes are not yet widely available in some countries and still in the early stage of development.

The big switch to hydrogen

The big switch to hydrogen

Hydrogen boilers are boilers that use hydrogen as a fuel source instead of traditional fossil fuels such as natural gas or oil.

They work by combining hydrogen and oxygen in a process called combustion to produce heat, which is then used to generate hot water or steam for heating buildings or generating electricity.

Hydrogen boilers are considered a clean energy source because they produce only water vapor as a byproduct, unlike fossil fuel boilers which produce carbon dioxide and other pollutants.

They are still in the early stage of development and not yet widely available for commercial use.
