Building Surveying
The Practice provides advice on a wide variety of property and construction methods. This includes the refurbishment, repair and alterations of existing buildings, as well as new construction.

Building Surveying is a very broad field and the properties range from residential to commercial and industrial buildings of all ages. Commonly, the services include the design and specification of building works, and the administration of building contracts.

Schedules of Condition are also prepared to create a record of a building, often in connection with a lease agreement or building works.

Party Wall and Neighbourly Matters
The Party Wall etc. Act 1996 provides a framework for the resolution of differences between neighbours regarding certain buildings works, and requires Building Owners (the owners of the property who are having work done), to notify Adjoining Owners in advance.  In many cases, the parties will reach agreement between themselves.  However, if they are not able to do so, the Act requires the appointment of a Surveyor for each party, or an Agreed Surveyor to resolve the differences.

The type of work covered by the Act includes work to party structures, work to buildings on a boundary, the erection of new walls on a boundary, and excavations close to an existing building or structure to a depth lower than the bottom of the nearby foundations.  The Act gives Building Owners certain rights, including the right to do works to parts of buildings which they do not actually own.

Having worked for some years in London, where the party wall legislation existed before the introduction of the national Act, John Naish has experience of resolving party wall disputes for more than 20 years. Since 2002, he has taken an active role in running the Thames Valley Branch of the P&T Club, a national organisation for professionals dealing with party wall matters. Construction projects often require access on to or over neighbouring land, and the provisions of the Party Wall etc. Act and the Access to Neighbouring Land Act, are not always available. Assistance is provided in drawing up access agreements and crane and scaffolding licences.

Project Management, Project Monitoring and Employers Agent
Clients commissioning construction projects have differing needs depending on the extent and complexity of the project, and their own resources and experience. The Practice is able to tailor support services to suit the client’s requirements and budget.

We recently completed a £2.5 million Design and Build contract for a new Business Aviation Terminal at Oxford Airport as Client’s Agent.
Expert Evidence for Building & Boundary Disputes
Since 1989, John has prepared Expert Witness Reports for construction and boundary disputes, including acting as Single Joint Expert. Evidence has been given in both Court and arbitration hearings.

Building Surveys
Building surveys and inspections of commercial and industrial property are undertaken for a number of purposes, including the following:
  • Pre-acquisition assessment
  • Stock condition
  • Planned maintenance
  • Building pathology
  • Reinstatement cost assessments for insurance purposes
  • Fire or flood damage assessment
  • Fire risk assessments
  • Schedules of Dilapidations
  • Vendor’s survey
  • Development appraisal
  • Pre-alteration assessment
  • Measured survey
The survey and the report are tailored to suit the client’s requirements and their intended use of the building. Advice is given on the need to engage specialist investigations into building services, deleterious materials etc.

Fault Diagnosis and Remedial Advice
Investigations into the cause of faults in buildings are an increasing part of our work, and the advance in construction technology brings new challenges.  Investigations are undertaken on buildings of any age.

Guidance is given to both Landlords and Tenants in respect of the obligations contained in the repairing covenants of commercial leases. This commonly includes the preparation of a Dilapidations Claim on behalf of the Landlord, or the defence of a claim on behalf of a Tenant, but advice is also given to assess the extent of liabilities to assist financial planning. As well as assessing the condition of the building, care is required when interpreting the extent of liabilities by careful examination of the lease clauses.
