If you are planning a project which involves works to the ‘Party Wall’ (Party Wall is a wall shared by two owners of two properties) This mainly applies to terrace or semi-detached properties) or if you are building an extension with new deeper foundations within 3 mts. or 6mts of the adjoining owners wall; you may need to serve ‘Party Wall Notices’ under the Party Wall etc. Act. 1996. This may affect your project works and time-scale. Normally a Party Structure Notice has a time frame of two months and a Section 6 notice has a time frame of one month.
Arc 3 strives to provide a service that assists both the Building Owners and the Adjoining Building Owners. Once you appoint the ‘Principal’ to act as your Party Wall Surveyor, he will ensure you are protected by the Act and assist in avoiding extra costs or project delays, by receiving all the necessary information one needs for the notifiable works before the project commences on site to the relevant areas.
For Building Owners and Neighbours (Adjoining Building Owners) alike, our Party Wall Services will include the following: Based in London and covering Wandsworth, Clapham, West Wickham, and Kent

Subject to the proposals under sections 1, 2 and/or 6 of the Party Wall etc. Act 1996, the works may place a duty on the Building Owner to provide a written notification to the neighbours (Adjoining Owners), at least one month (two months for section 2) prior to the start on site. Building Owner undertaking the work is normally liable to pay the adjoining owners surveyors costs which could range from £500 to £3750 or more per surveyor subject to the complexity of matters. Further advice will be provided if requested, once the notices are served and drawings and proper documentation provided.
