Planning Permission Requirements for Double Storey Side Extensions

Planning Permission Requirements for Double Storey Side Extensions

When planning a double storey side extension, understanding the planning permission requirements is essential. These requirements vary depending on location, size, and design. Generally, planning permission is necessary due to the impact on street appearance, though new permitted development rights may allow for extensions up to two storeys in certain cases, subject to specific criteria.

One key factor is the distance from the original house. Extensions must not exceed 3 meters from the original house and must be at least 7 meters from the rear boundary. Furthermore, the extension should not cover more than 50% of the land area around the original building. These restrictions help preserve the aesthetic appeal of the property and its surroundings.

Permitted development rights also significantly influence the planning permission requirements for double storey side extensions. Such rights may permit extensions up to two storeys in specific areas, provided they meet necessary criteria. If an extension exceeds these limits or does not comply with the conditions, planning permission may be required.

Despite the streamlined process offered by permitted development rights, common reasons for planning permission denial persist. These can include issues related to the extension's design, its impact on the street appearance, or non-compliance with local regulations. Homeowners must carefully consider these factors to ensure their double storey side extension aligns with required standards.

In summary, the planning permission requirements for double storey side extensions are complex and vary based on specific circumstances. It is crucial for homeowners to consider the distance from the original house, permitted development rights, and local regulations to ensure compliance and meet necessary requirements.

Building Regulations Compliance: A Crucial Aspect of Double Storey Side Extension

Building Regulations Compliance: A Crucial Aspect of Double Storey Side Extension

Awareness of the building regulations that govern the planning of a double storey side extension is essential.

The main goal of building regulations is to protect the public and prevent hazards such as collapse, fire, and vibration.

When planning a double storey side extension, it is essential to be aware of the building regulations that govern the process. These regulations ensure that extensions are safe, structurally sound, and do not compromise the integrity of the existing building or neighboring properties. Their primary objective is to protect the public and prevent hazards such as collapse, fire, and vibration.

In terms of safety standards, building regulations stipulate that extensions must be designed and constructed to ensure the stability and security of the existing building, as well as the surrounding structures and foundations. This is particularly crucial for semi-detached or detached houses, which are susceptible to seismic activity and other external forces. To ensure compliance, extensions must meet minimum requirements for structural integrity, providing adequate shoring, anchorage, and strengthening to resist external loads such as wind and earthquakes.

In addition to safety standards, building regulations also cover important aspects such as drainage, ventilation, and basic services. For example, regulations require extensions to connect to the existing domestic water supply and drainage system unless otherwise agreed upon with the local water authority. Furthermore, regulations stipulate that extensions must be designed to minimize the risk of moisture damage by incorporating features such as slope pressurization and ventilation systems.

Documentation required for compliance with building regulations varies depending on the jurisdiction. Typically, it includes submission of detailed plans and cost estimates, along with certification from a qualified structural engineer. Regulations may also require specialized materials or techniques, such as fire-resistant board or specialized drainage systems. To avoid administrative penalties, it is crucial to carefully review and comply with all applicable regulations.

By familiarizing yourself with building regulations and ensuring that your double storey side extension meets the required standards, you can minimize the risk of costly delays, penalties, or disputes. Moreover, compliance will help you create a safe, functional, and attractive extension that benefits both you and your neighbors.
