In the world of construction and property development, a nuanced understanding of legal frameworks is essential for fostering smooth progress and maintaining positive relationships with neighbours. The Party Wall etc. Act 1996 serves as a crucial guide, especially when constructing new walls along the line of junction. In this blog post, we will delve into the nuances of Section 1(2) and Section 1(5) notices, exploring the rights of entry that accompany these processes. Additionally, we’ll shed light on the implications for an adjoining owner who does not consent to a Section 1(2) notice and the potential ramifications for future construction plans.

Understanding the Party Wall etc. Act 1996

Enacted in the United Kingdom, the Party Wall etc. Act 1996 establishes a framework for preventing and resolving disputes between property owners concerning party walls, boundary walls, and excavations near neighbouring buildings. When constructing new walls along the line of junction, compliance with legal procedures is crucial to ensure adherence to the Act.

Section 1(2) Notices

Section 1(2) of the Party Wall etc. Act 1996 mandates serving notice to adjoining owner(s) where one owner intends to build a wall on the boundary line. That is, partly on their own land, and partly on their neighbour’s land.

This notice must include essential details such as the name and address of the building owner, the nature and particulars of the proposed work, the start date of the work, and its expected duration. Providing comprehensive information in the Section 1(2) notice is crucial to ensuring that adjoining owners are well-informed about the upcoming construction and can raise any concerns they may have.

Section 1(5) Notices

In addition to Section 1(2) notices, Section 1(5) notices may be required under specific circumstances. Section 1(5) pertains to cases where building owners intend to carry out work solely on their side of the party wall or within their land.

If an owner intends to build a wall up to the boundary line, but entirely on their own land, then they need to serve a notice on their neighbour.

Rights of Entry

The Party Wall etc. Act 1996 grants certain rights of entry to building owners to facilitate the construction of new walls along the line of junction. These rights include access to the adjoining owner’s land for the purpose of carrying out the necessary work. However, these rights are not absolute and must be exercised with due consideration for the rights and interests of the adjoining owner. Furthermore, if a notice is not served, then there is no right to enter on to the adjoining owner’s land to construct the wall.

Implications for an Adjoining Owner Who Does Not Consent to a Section 1(2) Notice

If an adjoining owner does not consent to a Section 1(2) notice, there are important implications to consider. In such cases, the wall must be built entirely on the building owner’s land. However, if the wall is built wholly on one owner’s land, then it is not a party wall, and the adjoining owner forfeits the ability to enclose upon or use that wall for their own construction in the future.

This decision can have significant consequences, particularly if the adjoining owner envisions erecting their own extension down the line. If the wall is built entirely on one owner’s land, it may create challenges in the future concerning waterproofing the gap between the two extensions, as well as potential maintenance issues. In contrast, consenting to a wall being built partly on the adjoining owner’s land may offer more flexibility and collaboration for future construction projects.


Building new walls along the line of junction under the Party Wall etc. Act 1996 involves a meticulous and considerate process. Section 1(2) and Section 1(5) notices play pivotal roles in informing adjoining owners about the proposed work, while the rights of entry provided by the Act ensure that building owners can carry out their construction activities efficiently.
