About Johnstruct Ltd.

We undertake planning, design, supply, erection and the complete steel frame package as a turnkey offering or elements thereof and as required. 

JOHNSTRUCT was formed over 45 years ago by Roy Johnson. JOHNSTRUCT originally provided agricultural, structural and mechanical services, predominantly to the farming community.  Roy's expertise was mainly in grain handling and  agricultural machinery, Roy could turn his hand to most things.  JOHNSTRUCT had a small workshop and excellent team of in-house fabricators and agricultural engineers - which between them, were called to make & mend all manner of weird and wonderful contraptions..

In the late 1980's Richard Allen joined JOHNSTRUCT bringing a wealth of Steel Framed building experience to the fold. The company moved from Fyfield, Ongar to Nether Hall in Moreton (Essex) in 1997 removing the workshop element.  In 2009 Roy sadly passed away leaving Richard to take JOHNSTRUCT to a new chapter.  JOHNSTRUCT predominately focused on all variations of steel framed buildings venturing in to historic barn refurbishment and general building services provision.

A recent key milestone in JOHNSTRUCTs history was in early 2019 when Richard sadly & suddenly passed away. As with Roy, Richard at 71 years old had a wealth of experience and knowledge - Between Roy and Richard, JOHNSTRUCT has established a core network of trusted suppliers and contractors and of course an excellent reputation with providing a no-nonsense "one stop shop" service for all things steel frame buildings plus all the supporting elements.

After a period of uncertainty Richards son, Mark, gathered up the reigns of running JOHNSTRUCT Ltd.  This third chapter in the JOHNSTRUCT history book has gained more and more momentum in 2020 - with a strong order book and a loyal customer and supplier base, Mark & the JOHNSTRUCT Ltd.  team continue to evolve and fine tune a tailored offering.   

Mark is extremely keen to honour the work that his father started - and not change the traditional values and services originally offered by JOHNSTRUCT.   

Mark brings a wealth of Engineering experience from large scale infrastructure and the asset management side of engineering.  A Civil Engineer, Mark has predominantly worked in Civil and Mechanical Engineering. Mark left school at 16 and started drafting (parallel motion drawing board) before he then went on to use CAD and study Civil Engineering and Engineering Management at Degree level.  Mark Joined the Railtrack Graduate training scheme in 1997 and has undertaken many engineering roles, more recently at a Principle Engineer level in the Technical Authority for Network Rail.  Mark has held senior engineering positions and worked for a number of infrastructure and manufacturing companies. Mark has worked in the USA, Canada and Europe.

Mark prides himself as being a practical engineer, he is equally happy installing a bathroom or building a log cabin as he is designing and setting out the levels on a complex permanent way rail re-alignment scheme or designing the foundations for a complex steel frame building.  His knowledge in concrete and structural steel design and his Project Management experience now playing a significant factor in the future of JOHNSTRUCT Ltd.  Mark is affiliated MIET, MAPM, BSc (Hons), we are RIDBA members and are consulted on some of the local planning policy and plan with Local Planning Authorities.

With the support of JOHNSTRUCT's core team and our fantastic suppliers, Johnstruct continues to provide a high quality, cost effective and hassle free service to all customers.

Take your idea and make it a reality with JOHNSTRUCT  Ltd.

From an initial enquiry through planning, right through to site preparation and build -  JOHNSTRUCT can offer the whole package. If you would prefer to undertake some elements or have a contractor preference - we are equally happy to oversee the work to ensure continuity at any handover or overlap points.

We like to work collaboratively and transparently with our customer.  Whilst we're able to make suggestions and an unbiased view at the design stages we're more than happy to make the difficult every day decisions often required when making your building a reality.


We listen, we're open minded and most importantly we are small and flexible enough to accommodate any bespoke needs / design requirements. Every customer is unique to us.

All of our work is undertaken in a manner that we would expect of our own building.  Customer engagement levels vary from customer to customer but we're happy to be left alone or equally have a regular "coffee" discussion or meeting to talk over the job.

EXTRA's - The site preparation and the building tend to take up 1/3 each of the overall work involved.  The last 1/3 can be the most challenging.  JOHNSTRUCT have provided everything from mezzanines, rain water harvesting, specialist climate control systems, toilet facilities and office accommodation.

Our UNIQUE SELLING POINT is that we're independent and very flexible / accommodating.  With one phone call, we take action and do all the legwork on your behalf - We're a very principled and ethical company, we work taking these values with us in everything that we do.
