Established in the 18th century, No.20 Portman Square was originally designed for the notorious Countess of Home, who commissioned a sophisticated palace purely for enjoyment and entertainment. Fusing 18th century splendour with 21st century style across three exquisite Georgian townhouses, today Home House is London’s iconic private members’ club. Offering an exceptional range of facilities in the heart of Marylebone, including restaurants, bars and lounges, a boutique gym, 23 characterful bedrooms, private dining and party rooms, a beautiful courtyard garden and an unrivalled members events calendar – the club is really a true ‘home from home’. Membership applications are considered monthly by the membership committee, with no interviews, no board of selectors you must appear before or esoteric initiation rites.


With a heritage of over 250 years, protecting and preserving the environment in which Home House operates has always been at the core of their operations. Home House is committed to minimising its impact on the environment and making sure their members feel confident that their time spent at the club is ethical. From sustainable supplier sourcing to ensuring energy efficiency and supporting local community programmes to improve the environment in which they operate, the club will continue to make improvements to help foster a sustainable future.

Case study


One of the main focuses and highlights of Home House’s environmental sustainability journey started with them collecting their energy consumption and conducting their first carbon assessment across Scope 1, 2 and scope 3 emissions from their own operations. In addition, the Members Club identified its company dependencies and impact on biodiversity. These results and commitments have also been submitted to the Science Based Targets initiative (SBTi) for official validation. These actions places Home House among the top few thousand companies in the world in terms of climate leadership. Home House switched to 100% renewable electricity in 2022 and has set up further ambitious climate targets such as reducing gas usage by 10%, and reducing electricity usage by 10% year on year to achieve net zero and in order to help tackle global warming.

Case study


As a one of London’s most influential members’ clubs, Home House introduced a new Supplier Code of Conduct to meet the growing expectations of all stakeholders such as their own members, shareholders, and non-governmental organisations. As such, they are increasingly incorporating sustainable sourcing into their supply chain management processes to identify and mitigate risks, while establishing solid, lengthy partnerships with suppliers. Their food suppliers are certified to meet consumer demands regarding animal health and welfare as well as public health. All paper and cardboard usage for their offices is FSC certified, within the club itself it has ceased the use of plastic straws replacing them with paper alternatives.

Case study


Home House is an active member of the Baker Street Quarter Partnership, a Business Improvement District (BID) which is a defined geographical area which the local businesses have voted to invest in collectively to improve its environment. The BID aims to transform the area around Baker Street and create a first class environment for everyone by creating small public gardens such as the Wild West Garden and by planting trees on Baker Street. In addition, to ensure a sustainable future, the Baker Street Quarter Partnership is working on many different projects such as improving the air quality of the area and to put in place smarter recycling to reduce traffic and emissions.

Case study


Home House endorses seven of the United Nations SDGs and is actively working to encourage a social responsibility approach amongst their members, guests, partners, employees, and wider community. It has already initiated and has future plans to implement more initiatives to achieve their social responsibility commitments. For example, the first of their internal goals is creating a comfortable work place, this is achieved by implementing policies that promote fairness, respect, and inclusivity, as well as providing resources and support for employees to perform their jobs effectively. Another relates to putting in place ethical environmental initiatives such as the new creation of a recycling community that seeks to engage their stakeholders and overall minimise their impact on the planet through social action. Home House has also put in place policies such as ensuring the hotel is clean and well-maintained, providing excellent customer service, personalizing the guest experience, and soliciting feedback from guests to better improve guest satisfaction. By combining policies that create a comfortable workplace with a focus on increasing guest satisfaction, Home House would be creating a virtuous cycle which can lead to a more successful and sustainable business.


Home House are committed to continuous progress with their sustainability efforts. To build upon the Butterfly Mark certification, they are actively exploring new initiatives to further reduce their environmental impact and promote social responsibility. Their focus is on implementing innovative energy-saving technologies, increasing waste reduction and recycling measures, sourcing sustainable materials, and supporting local community projects. Additionally, Home House aim to collaborate with like-minded organisations and industry leaders to drive positive change within the hospitality sector. By staying dedicated to their sustainability goals, they strive to inspire and lead the way towards a greener and more conscious future for their members, community and the planet.
