O A STUDIO Architectural Technicians
Building Defects Forensics Consultancy has been established by O A STUDIO and is to become a charity under that name to provide independent, experienced, and practical advice on building defects, construction issues, and associated disputes for those who can aford it and those that can not.
With more than 50 years’ experience in the building and construction sector, beginning with the design and supervised conversion of a bungalow into a house at the age of 14, the consultancy brings a depth of technical knowledge developed through long-standing practical involvement in the industry.
Scope of Building Forensics
The scope of building forensics is to identify faults, failures, defects, and poor workmanship in construction and building works. The consultancy provides independent assessment where projects have gone wrong, where workmanship is disputed, or where clients need clear technical advice to resolve problems with builders, contractors, or unfinished works.
Professional Background
The consultancy is led by a qualified senior technician with 50 years of experience in the building and construction sector. This background provides a strong practical and technical foundation for the investigation of defects, failures, workmanship issues, and construction-related concerns. See link below
HOW DO WE START WORKING FOIR YOU
Where appropriate, an opening assessment report can then be prepared from available photographs, documentation, correspondence, drawings, quotations, reports, or other relevant records. This initial review helps identify the likely issues, the evidence required, and the most suitable next steps before any further instruction or inspection is considered.
Following the opening assessment, the proposed way forward and any associated costs can be agreed with the client before further work is undertaken.
Where a matter proceeds towards formal dispute resolution or litigation, expert witness services can also be provided, including independent expert reports, technical opinion, review of supporting evidence, and assistance in presenting building defect issues clearly for solicitors, insurers, mediators, adjudicators, or the court.
The consultancy’s approach is based on careful inspection, practical construction knowledge, balanced judgement, and clear reporting. Each matter is considered on its own facts, with the aim of identifying the relevant issues and presenting findings in a clear and accessible manner.
Mediation and Its Uses
Mediation can provide a practical and cost-effective route for resolving building defect disputes without the need for prolonged formal proceedings. It allows the parties to consider the technical issues, the likely cause of the defects, the scope of remedial works, and the commercial realities of reaching an agreed outcome.
Within this process, independent technical assessment can assist by clarifying the matters in dispute, identifying the evidence required, explaining possible causes, and setting out reasonable options for repair or settlement. This can help parties make informed decisions and support constructive negotiations.
- Clarifying the nature and extent of alleged building defects
- Supporting early resolution before costs increase
- Helping parties understand technical evidence and remedial options
- Assisting solicitors, insurers, contractors, and property owners during negotiations
- Providing independent technical input to support fair and practical settlement discussions

How We Work
The process usually begins with an initial telephone consultation, provided FREE without obligation, to understand the nature of the building defect concern, the background to the matter, and the particular issues faced by the client.
Where appropriate, an opening assessment report can then be prepared from available photographs, documentation, correspondence, drawings, quotations, reports, or other relevant records. This initial review helps identify the likely issues, the evidence required, and the most suitable next steps before any further instruction or inspection is considered.
Following the opening assessment, the proposed way forward and any associated costs can be agreed with the client before further work is undertaken.
Where a matter proceeds towards formal dispute resolution or litigation, expert witness services can also be provided, including independent expert reports, technical opinion, review of supporting evidence, and assistance in presenting building defect issues clearly for solicitors, insurers, mediators, adjudicators, or the court.
Professional Support for Construction Success
Benefits of Mediation
Mediation offers a structured but flexible process that can help parties resolve building defect disputes more efficiently and with greater control over the outcome. It encourages practical discussion, reduces confrontation, and allows technical issues to be considered alongside cost, time, and commercial considerations.
• Can reduce legal and professional costs compared with prolonged dispute proceedings
• May achieve a quicker resolution than court or formal adjudication routes
• Allows the parties to keep greater control over the final agreement
• Provides a confidential setting for open and constructive discussion
• Helps preserve working or commercial relationships where possible
• Encourages practical remedial solutions rather than purely adversarial outcomes
• Supports informed decision-making through independent technical input
• Requires both parties to understand, accept, and engage with compromise, recognising that mediation is not about one party winning but about reaching a workable settlement
Court Costs and Likely Timescales
By comparison, court proceedings can involve substantial legal, expert, and administrative costs. Current civil court fee guidance for England and Wales shows that issuing a money claim above £10,000 and up to £200,000 may require a court issue fee of 5% of the claim value, while claims above £200,000 may attract a £10,000 issue fee. These figures relate to court fees only and do not include solicitors’ fees, barristers’ fees, expert witness fees, preparation time, applications, hearings, or enforcement costs.

Example Case Study: High-Value Building Defects Claim
Concerned the alleged failure of a building conversion to meet applicable building regulation requirements, together with the alleged failure of relevant professionals to identify and check deviations during the works.
The claim value was approximately £1.1 million. Costs to date were approximately £500,000. The building period concluded in 2020, with subsequent matters arising in 2022. Liability was admitted at 100%, and mediation took place in July 2026 in relation to the cost of the remedial works.
The matter is listed for a court hearing in March 2027, demonstrating the potential timescale between completion of works, emergence of dispute issues, mediation, and a final court date. This example illustrates why early independent technical input and mediation can be valuable in narrowing the issues, assessing the cost of works, and supporting settlement before further litigation costs are incurred.
Mediation had a significant impact by moving the dispute from a broad liability-based argument towards a focused assessment of the cost and scope of remedial works. As liability had already been admitted, the mediation process provided an opportunity to narrow the remaining dispute, test the reasonableness of the claimed costs, and explore settlement before the parties incurred further preparation and hearing costs ahead of the March 2027 court date.
Expert witness input in this type of case can be critical in separating liability from quantum, reviewing the technical basis of the remedial works, and providing an independent opinion on whether the proposed scope and costs are reasonable. This can assist both mediation and any later court process by narrowing the matters that remain genuinely in dispute.
It is hoped that, before instructions are issued to counsel and experts for the four-day hearing in March 2027 at an estimated further cost of £220,000, a mediation settlement can be completed before September 2026.rt guidance on planning applications that navigate complex regulations efficiently.
Example Case Study: Small Extension Dispute
A second example concerned a small domestic extension with an agreed value of approximately £38,000. The builder was initially considered suitable, but after three years the works remained incomplete, despite approximately £36,000 having been paid. The builder then sought further payment.
The construction works began in 2021. No court action was taken. Instead, mediation took place in 2024 and helped bring the matter back to a practical route towards completion. The project was then completed mostly with the original builder, although some outstanding works and defect items remained.
The mediation process helped avoid formal litigation, enabled the family to move back into the property in 2025, and prevented further payments being made to the builder. Additional costs were still incurred to complete unfinished and defective works, but the dispute was managed without court proceedings and with a practical focus on achieving occupation and completion.
Summary: This example demonstrates how mediation can provide a practical alternative to court action in a lower-value domestic building dispute. Although the works had been significantly delayed and further completion costs were required, mediation helped bring the parties towards a workable outcome, avoided litigation, prevented further payment to the builder, and enabled the family to return to occupation.
Expert witness involvement in a lower-value domestic dispute can also be valuable where the parties need an independent view on the standard of workmanship, the extent of incomplete or defective works, and the cost of bringing the project to a reasonable conclusion. This can help prevent the matter from escalating unnecessarily while still protecting the client’s position.
