About

Meet Lewis Osborne

Lewis Osborne is the founder and director of Tashi Structures Ltd.

With almost 20 years of structural engineering experience, Lewis has worked on projects ranging from domestic alterations and bespoke private homes through to multi-million-pound commercial developments, schools, healthcare facilities, industrial buildings and major residential schemes.

Having spent his career within leading engineering consultancies, Lewis established Tashi Structures to provide clients with a more personal, responsive and practical service. Clients deal directly with the engineer undertaking the work, ensuring clear communication, efficient decision-making and solutions that are technically robust without unnecessary complexity.

Lewis believes structural engineering should be straightforward, pragmatic and focused on helping clients move their projects forward with confidence.

Our approach

How we work

  1. Initial discussion. We start by understanding your project, concerns and objectives. In many cases, a brief phone call or email exchange is sufficient to establish the most appropriate scope of structural input.
  2. Site inspection & assessment. Where required, we undertake a site inspection to assess the existing structure, identify constraints and gather the information needed to provide informed engineering advice.
  3. Advice & design. We develop practical structural solutions tailored to the specific requirements of the project. This may include structural inspections, defect diagnosis, feasibility advice, structural calculations, specifications or detailed design.
  4. Reporting & delivery. Our findings, recommendations and designs are presented in a clear and practical format suitable for Building Control approval, contractor pricing, project decision-making and construction.
  5. Ongoing support. We remain available to assist throughout the project, answering queries, reviewing contractor proposals and providing additional engineering input where required.

Independent

Why choose an independent consultancy?

Tashi Structures combines the experience and technical capability typically associated with larger engineering consultancies with the responsiveness and personal service of an independent practice.

Clients deal directly with the engineer undertaking the work, ensuring clear communication, efficient decision-making and continuity throughout the project. Without complex management structures or multiple layers of administration, we are able to respond quickly, adapt to changing project requirements and provide practical engineering advice focused on achieving successful outcomes.

Our flexible approach allows us to draw upon a trusted network of experienced structural engineers, civil engineers and technical specialists when required, providing access to additional expertise and resource without compromising the direct, personal service that clients value.

What our clients say

Lewis from Tashi Structures was very friendly and professional and was very thorough with his inspection of our garage. Lewis’s report was very detailed and explained all the issues and how to move forward. I would highly recommend Lewis.

Ashley Hockley

Lewis carried out a structural inspection of a property we are in the process of purchasing. We received a highly detailed and thorough report that was of excellent quality. Lewis was professional and easy to communicate with throughout, including contacting the estate agent directly to organise his site visit which made our lives that bit easier. I wouldn’t hesitate to recommend his services.

Guy Ellis

I needed a structural engineer to perform a survey of my property for issues with cracking. Lewis arrived at the arranged time and did a thorough examination of the property explaining important points as he went around and giving an initial assessment at the end of the visit. This was then followed up by the written report within a week which was detailed and covered what had been discussed verbally. His fee was in line with others that had provided quotes. I would recommend him!

Rob Stock

I contacted Tashi via a local search facility for Structural Engineers. I had ongoing issues with my roof which I needed advice on how to proceed. I found Lewis very helpful he gave me good advice on how to proceed with a full report and practical advice as I needed it.
