Yes, you can raise a party wall, and it's a relatively common practice.
Raising a party wall often occurs when a homeowner wants to extend their property, such as building an addition or converting a loft. Since party walls provide structural support and separation between adjoining properties, any work affecting them is governed by specific regulations. The Party Wall Act provides a framework for handling such situations.
Here's a breakdown of key considerations when raising a party wall:
-
Party Wall Act: Any work on a party wall, including raising its height, falls under the Party Wall Act. This act requires you to notify your neighbor(s) before starting any work.
-
Notice: You must serve a formal "Party Wall Notice" to your adjoining neighbor. This notice outlines the proposed work, including details about raising the wall's height.
-
Neighbor's Consent: Your neighbor has the right to either consent to the work or dissent. If they dissent, the Party Wall Act provides a mechanism for resolving disputes, usually involving a surveyor.
-
Surveyor(s): If a dispute arises, the Act allows for the appointment of a surveyor (or surveyors). The surveyor(s) will assess the proposed work, ensure it's carried out correctly and safely, and agree on a "Party Wall Award."
-
Party Wall Award: This legally binding document details the scope of the work, how it will be carried out, and any necessary safeguards to protect your neighbor's property. It also clarifies who is responsible for costs.
-
Cost Responsibility: Generally, the person undertaking the work (i.e., raising the party wall) is responsible for the costs associated with the Party Wall Award and any associated damage to the adjoining property that results directly from the work. However, if the raising of the party wall benefits both properties, costs may be shared.
-
Planning Permission: Raising a party wall may require planning permission from your local authority, in addition to complying with the Party Wall Act. Always check with your local planning department before commencing any work.
-
Structural Considerations: Ensure that the existing wall is structurally sound enough to support the additional height. A structural engineer should assess the wall and provide necessary calculations and specifications.
-
Example Scenario: Imagine you are extending your kitchen and need to raise the shared wall with your neighbor to accommodate the new structure. You must serve a Party Wall Notice. If your neighbor consents, you can proceed with the work as planned. If they dissent, a surveyor will be involved to agree on an award to protect both your and your neighbor's interests.
In summary, raising a party wall is possible but requires careful planning, adherence to the Party Wall Act, and consideration of structural and planning requirements. Early communication with your neighbor is crucial for a smooth process.
