Chalfont Court
Designated higher-risk building (HRB)
Chalfont Court, situated on Baker Street in the heart of Marylebone, London NW1, is a distinguished red-brick mansion block known for its elegant architecture and proximity to Regent’s Park. Whether you’ve been a resident for years or have recently acquired an apartment, planning a refurbishment in Chalfont Court now requires adherence to stricter safety regulations. The introduction of the Building Safety Act 2022 has brought significant changes to how refurbishments are approached in higher-risk buildings like Chalfont Court. Ensuring compliance is essential to protect your investment and enhance the safety and comfort of your home.
Understanding the Building Safety Act 2022
The Building Safety Act 2022 was enacted to enhance safety standards in residential buildings, particularly those over 18 metres tall or with seven or more storeys. This legislation established the Building Safety Regulator (BSR) and introduced the role of the Principal Accountable Person (PAP) to oversee building safety compliance. For residents of Chalfont Court, this means that any refurbishment plans must align with these enhanced safety standards, from initial design to final execution.
What Makes Chalfont Court a Higher-Risk Building?
Chalfont Court qualifies as a higher-risk building under the Building Safety Act 2022 due to its height and number of storeys. This classification necessitates additional oversight to ensure that refurbishments meet stringent safety requirements, safeguarding all residents by maintaining fire safety measures, ensuring structural integrity, and preventing modifications that could compromise the building’s safety.
Why Compliance Matters
Refurbishing in Chalfont Court now requires careful planning to align with the Building Safety Act 2022. All alterations, from kitchen upgrades to structural changes, must comply with these enhanced safety standards. Certain types of work may require approval from the BSR or consultation with the PAP, especially modifications affecting communal areas, fire-resistant materials, or structural elements. Ensuring compliance protects your investment and contributes to the overall safety of the Chalfont Court community.

Embarking on a refurbishment project in Chalfont Court necessitates a thorough understanding of the building’s status and the regulations that apply. Begin by consulting with the building management or the Principal Accountable Person (PAP) to confirm Chalfont Court’s classification as a higher-risk building under the Building Safety Act 2022. This step is crucial to comprehend the specific safety protocols and requirements your refurbishment must meet.
Next, familiarise yourself with the enhanced safety measures mandated by the Act. This involves identifying any restrictions or additional approvals needed for your planned improvements. Understanding these regulations will help you plan your project effectively and ensure all aspects comply with the necessary safety standards.
Once you have a clear grasp of the regulations, engage in a detailed consultation with the PAP. Present your refurbishment plans for their review and approval, ensuring they align with the building’s safety protocols. This collaboration is vital to address any potential safety concerns and to make necessary adjustments to your plans before proceeding.
Securing the appropriate permissions is the next critical step. For higher-risk buildings like Chalfont Court, the Building Safety Regulator (BSR) serves as the building control authority. Additionally, as the apartments are likely leasehold properties, you will need to obtain a licence to alter from the freeholder or managing agent before proceeding with any significant refurbishment. This licence will not be granted unless you confirm that the proposed works will also obtain approval from the BSR.
Finally, working with qualified professionals is essential for ensuring compliance. At Antarris, we have a team of experienced architects, designers, and contractors who specialise in refurbishments for higher-risk buildings like Chalfont Court. By choosing trusted experts, you can ensure you obtain the necessary approvals for your project and that it is executed to the highest standards.

Common Refurbishment Projects and Considerations in Albert Court Mansions
Popular refurbishment projects include modernising kitchens and bathrooms, replacing flooring, and upgrading balconies or windows. Internal alterations, such as removing walls, require consultation with a structural engineer to ensure compliance with safety standards. External modifications must adhere to fire safety regulations, and balcony upgrades or window replacements often require approval from the PAP. Electrical and gas works should be completed by certified professionals, such as NICEIC-registered electricians or Gas Safe engineers, to meet current safety requirements.
Potential Consequences of Non-Compliance
Failing to comply with the Building Safety Act regulations can have serious repercussions. Non-compliance may result in fines, legal notices, or the need to undo completed work. It could also void your home insurance and deter potential buyers, negatively impacting the value of your property. Additionally, as a leaseholder in Chalfont Court, you are required to obtain a licence to alter from the landlord (freeholder) before starting any significant refurbishment. This licence will not be granted unless you confirm that the proposed works will also obtain approval from the BSR. Without both permissions, proceeding with refurbishment could result in legal disputes and project delays.
By adhering to the Building Safety Act, you safeguard your home, protect its value, and contribute to the overall safety of the building. Compliant refurbishments provide peace of mind for you and your neighbours, ensuring that all work meets the highest standards.
