About Us

We’re on a mission to provide our clients with the best possible value we can across their entire project. Not just with our fees.Passivhaus Structural Engineers Sheffield

We don’t just design the structural members shown on your Architect’s drawings and leave you to it.

We start by exploring a range of potential structural solutions to consider:

  • how well they deliver on your dream,
  • how practical, safe and quick they are to build,
  • what impact our designs have on the planet
  • what temporary works will be required for each,
  • and what the relative cost of each will be to you.

Only once we’ve agreed on a solution you’re happy with from a cost, practicality and design point of view will we put pen to paper and finalise your design.

We’ll then work with you, your builder and your architect to anticipate any potential problems on site to help the build go as quickly and smoothly as it can.

We also realise that things change as building projects develop so our fee is based on providing a service which is comprehensive but which allows you some flexibility.

Our Team

Chris & Max are involved in all  our ongoing design projects. They bring a wealth of experience and attention to detail to every job.

Chris Jarvis

Chris is an experienced Structural Engineer who enjoys the challenge of designing complex structures of all sizes. He has designed 27 storey reinforced concrete frames, Leisure Buildings, Industrial structures, New Build Houses and Extensions and also small structures where you never thought an Engineer would be required! Chris enjoys getting involved early in a project to help advise Clients and Architects of possible structural options. He also has experience offering Construction Stage support to helping Contractors with on-site queries.

He graduated from the University of Sheffield in 2014 and stayed in Yorkshire following his graduation with his young family and dog. In his free time he enjoys dog walks in the Peak District and Sherwood Forest as well as going to watch the Sheffield Steelers Ice Hockey team. During the Summer he plays cricket for a local Sheffield team when he hasn’t managed to injure himself playing it!

Max Kenworthy

Max is a talented Structural Engineer who’s developed a good range of experience since graduating from the University of Sheffield in 2021.

Max is a keen caver. He stayed in Sheffield after graduation to make the most of the Peak District’s cave networks and enjoys heading off on adventures whenever he can.

Steve Smith

Steve is our Office Manager and is responsible for ensuring everything runs seamlessly at JAM.

He’s always had a keen interest in creative projects and a fascination with how each stage of the process unfolds.

Outside of office life, you will usually find Steve running, cycling or walking his dogs through the peaks & around the reservoirs that surround Sheffield. He’s also a passionate supporter of Everton FC, but doesn’t like to admit it sometimes.
