Our services

Anthony-Johnson provides a range of Engineering Services, covering the Civil and Structural Sector. The Practice engages in CDM, Structural design, Geotechnical Surveys, Property Surveys and assesments and provides services to Homeowners and Businesses alike. The Practice has extensive experience in Historic buildings conservation & design.

Historic Buildings

A historic area of England, the East coast around the Wash envelops many structures that were built before the inception of Building Act of 1878. As such, any design work should be considered from a sympathetic stand-point so as to avoid deterioration to the fabric of the existing structure.

Anthony-Johnson provides a range of services aimed at the assesment, conservation and restoration of Historic buildings in the most sympathetic manner possible. These include Site investigations, structural design and specifications.


Structural Design

Design of Steel, Timber and Masonry Structures and Structural Members. Design using Concrete.


Development of Layout plans, detailing and production of Drawings for Planning Applications, Building Regulations and Construction Phase
Foundation Analysis.

Foundation design including Pad, Raft and Strip footings. Design of retaining walls and soak-aways.


Condition Surveys

Anthony-Johnson provides condition surveys of entire residential and commercial structures, assesing the fabric of a building, areas of deterioration and conditions that may lead to future defects. Our reports can be used to put in place a system of rememdial measures or works to rectify defects and prevent future deterioration.

Historic Structural Assesments

Materials and techniques used in the construction of buildings before the Building Act of 1878 differ considerably from those used in modern buildings. Historic buildings may lack substantial foundations, have no damp proof course and rely on the use of "floating timber" floors, raised above "dirt" by no more than two feet. Applying modern building techniques and materials to such structures can inadventatly introduce rapid decay to the fabric of the building. Our understanding of such historic building practices allows us to investigate and assess such buildings, avoiding the confusion of modern building regulations.

Latest projects

The practice has an extensive portfolio of projects, ranging from Restoration design work to geotechnical surveys and structural surveys. Our core business remains structural design works, typically engaged by Architects. A Range of the Latest Projects Anthony-Johnson is engaged in:

Change of Use works to a Grade II listed Barn

The Practice has been engaged by a self-builder who has planning permission for change of use of an Existing grade II listed barn in Suffolk. As consulting Engineer to the client, the practice communicates proposals with the local Conservation officer and produces design works to ensure the structure meets Part A of the Building Regulations

Novel House Build Project

Having been Engaged by a Self Builder and working alongside the Architect, Anthony-Johnson carried out Geotechnical Surveys, produced foundation designs, lintel designs and steel frame designs to allow the construction of a house formed entirely from Durisol Blocks. These insulating blocks are formed from Hemp, pre-cast with cement binder and allow for an almost Lego Like construction of new structures. Turn the blocks on their side, add reinforcement and concrete to make lintels.

The Design of structural Elements to an Extension

Building an extension can appear a daunting task. Anthony-Johnson was engaged by a Primary School to conduct a geotechnical survcey and design foundations for an extension to a traditionally built School. The presence of Corbelled Brick footings to the original building meant that a raft foundation had to be used. Architectural details added complexity to the Raft, which had to take into account a retained masonry pier, protruding side wall and infill beam support.
