Party wall matters, boundary disputes and the issues around neighbouring properties can be highly complex, and failing to address them can have serious repercussions.

The Silver Difference

Our highly experienced team aims for innovative, practical and cost-effective solutions for anything from boundary issues relating to congested sites, party wall alterations, new wall constructions, basement excavations, loft conversions and building up to the boundary line. They work on behalf of the building owner and the adjoining owner to agree the ‘time and manner’ of works whilst protecting each party’s legal rights.

Party wall matters have been a speciality of Silver since its establishment in 1945. Originally acting under the London Building Act 1939 and, subsequently, the Party Wall etc Act 1996 which extended its provisions to England and Wales, our team has continued to thrive and expand. Today, we provide advice on projects ranging from mega basements to large regeneration developments, new build and refurbishment, including luxury residential, for public and private clients. The team’s understanding of the complexities involved provides clients with a straightforward service, aimed at ensuring that the required awards are completed on time and unnecessary delays and additional costs are avoided.

Dollar Bay, Canary Wharf

Client: Dollar Bay Developments Ltd
Service: Party Wall

Dollar Bay is a residential development overlooking Canary Wharf. Situated on the waterside of South Dock, the scheme incorporates a three-storey building and a 31-storey tower.

With 22 adjoining owners surrounding the site, Silver was appointed as the Building Owners Surveyor to agree the required Party Wall Awards.

Careful planning by the Silver team ensured that the development proceeded without delay and on programme, with the requirements of the Party Wall Act met. This has involved a coordinated and timely approach to the preparation of schedules of condition and agreement for each Award with the adjoining owners’ surveyors. Over and beyond the scope of the Act, the team also successfully agreed access onto neighbouring land in order to facilitate works.

Wavy Gate, Oxford, Student Accommodation

Client: A2Dominion Group
Services: Employer's Agent, Quality Management and Party Wall.

This scheme, so named by local school children after its distinctive "wavy gate" entrance design is situated in the heart of Oxford. Comprises 190 fully furnished, ensuite student rooms, a central landscaped courtyard acting as a communal area for students to socialise.

Given budget constraints, initial cost estimates based on a reinforced concrete frame questioned the development’s viability. It was therefore decided to use a prefabricated timber frame system which could save time and cut costs by around 9%. Silver visited EBS Elk’s main manufacturing plant in Austria with our client’s Development Team to acquire a 360 degree understanding of the component structure, process and ultimate sustainability of the building. Construction of both three and four-storey buildings, which covered 60,000 sq.ft., took only 10 weeks to achieve complete water tightness and which included installation of bathroom pods. Overall the project build took ten months from formation of ground floor slab to occupation.

With over 30 adjoining residential properties, party wall matters had to be addressed at the earliest possible stage to avoid delays. Our experienced party wall surveyors acted proactively, extending our role to act as Building Owners Surveyor, undertaking and issuing the necessary Awards within a tight, three month timeframe.
