Comprehensive structural engineering services for residential, commercial, and public sector projects. We deliver cost-effective, buildable, and compliant designs that bring your vision to life.
AJF Engineering Consultants is a leading Civil and Structural Engineering firm based in the North West, providing director-led consultancy services across the UK. Our team of Chartered engineers brings a wealth of experience to every project, offering bespoke structural design solutions that balance technical precision with commercial reality. Whether you are planning a small domestic extension or a complex multi-storey steel frame development, we ensure your project is delivered efficiently, safely, and to the highest professional standards.
Structural engineering is the backbone of any construction project. It requires a deep understanding of materials, loads, and forces to ensure buildings are safe, stable, and durable. At AJF Engineering, we go beyond basic compliance. We work closely with architects, developers, and contractors to create structural schemes that are not only robust but also optimised for constructability and cost. By engaging with the design team early, we can identify opportunities to simplify the structure, reduce material usage, and streamline the construction process without compromising on performance or safety.
Our approach is collaborative and transparent. We understand that every project has unique challenges and constraints. By maintaining all design work in-house and utilising the latest industry software, we provide fully coordinated structural solutions that integrate seamlessly with architectural layouts and building services. This attention to detail minimises on-site issues and ensures a smoother path from concept to completion.

Comprehensive Structural Design Services
We offer a wide range of structural engineering services tailored to meet the diverse needs of our clients. From initial feasibility studies to detailed design and construction support, our expertise covers all major construction materials and building types.


Residential Structural Design
We have extensive experience in the residential sector, providing structural designs for everything from individual bespoke homes to large-scale, volume housing developments and apartment blocks. Our team understands the importance of efficient design in the competitive housing market. We deliver practical solutions for foundations, load-bearing walls, floors, and roof structures that maximise space and minimise costs. Whether it is a new build, a conversion, or an extension, we ensure the structure supports the architectural intent while meeting all Building Regulations. For more insight on residential developments, explore our structural engineering projects.
Steel and Concrete Frame Design
For larger commercial, industrial, and mixed-use developments, we specialise in the design of complex steel and reinforced concrete frames. Our engineers use advanced 3D modelling and analysis software to design efficient frames that optimise material use and reduce carbon footprint.
- Steel Frames: Ideally suited for warehouses, industrial units, and multi-storey buildings requiring long spans and flexibility. We design portal frames, braced frames, and complex steel structures with a focus on ease of fabrication and erection.
- Reinforced Concrete: We design in-situ and precast concrete structures, including flat slabs, beams, and columns, often used for residential apartments and office buildings where durability, fire resistance, and acoustic performance are critical.
To see how we have delivered successful outcomes for complex structures, visit our Baltic Triangle, Liverpool project and Winnington Lane, Northwich project.
Foundations and Substructures
The stability of any structure depends on its foundation. We provide expert design for all types of foundations and substructures, tailored to the specific ground conditions of your site.
- Shallow Foundations: Strip footings, pad foundations, and rafts for sites depending on ground conditions and other contributing factors.
- Piled Foundations: For sites with poor ground conditions or heavy loads, we design piled solutions including pile caps and ground beams.
- Basement Design: We offer specialist design for residential and commercial basements, including retaining walls and waterproofing strategies, ensuring robust and watertight below-ground structures.
- Retaining Structures: We design various retaining walls, from gravity and cantilever walls to to inputting to the design of reinforced earth and sheet piling, to efficiently manage level changes across sloping sites.
Refurbishment, Alterations, and Extensions
Breathing new life into existing buildings often presents complex structural challenges. We have a proven track record in the refurbishment and alteration of existing structures. Whether it is removing load-bearing walls to create open-plan living spaces, adding new storeys to an existing building, or stabilising a historic property, our team provides sensitive and practical engineering solutions. We conduct thorough structural surveys to understand the existing fabric and design interventions that respect the building’s history while enabling modern use.
Design for Masonry and Timber
Traditional materials remain a core part of UK construction. We provide expert design for:
- Loadbearing Masonry: Designing efficient masonry structures for low to medium-rise residential and commercial buildings.
- Timber Structures: From traditional timber roofs and floors to modern engineered timber solutions like glulam and cross-laminated timber (CLT), promoting sustainable and rapid construction methods.

Technical Support and Construction Design
Our involvement does not stop at the design stage. We provide ongoing technical support during the construction phase to ensure the design is implemented correctly. This includes reviewing contractor proposals, responding to site queries, and conducting site inspections. We act as a proactive partner, helping to resolve any unforeseen issues quickly to keep your project on track.

Our Approach: Engineering Value and Efficiency
At AJF Engineering, we believe that good engineering is about more than just making a building stand up. It is about adding value to the project through intelligent design and proactive management.
Director-Led Involvement
Every project benefits from the direct oversight of a company director. This ensures that you have access to senior-level expertise throughout the lifecycle of your project. It fosters quick decision-making, clear accountability, and a high level of service that larger consultancies often struggle to match.
Focus on Buildability
A design on paper is only successful if it can be built efficiently on site. We place a strong emphasis on buildability, considering construction sequences, temporary works, and safety from the outset. By designing out complexity where possible, we help reduce construction risks and costs.
Collaborative Coordination
Structural elements do not exist in isolation. They must work in harmony with architecture and building services. We work closely with the wider design team, using 3D modelling to coordinate our structures with mechanical and electrical services, avoiding clashes and ensuring a smooth fit-out. This collaborative ethos extends to our work with developers and contractors, where we aim to be a solution-oriented partner rather than a hurdle.
Cost-Effective Solutions
We understand commercial pressures. Our engineers are trained to seek out the most economical structural solution without compromising quality. By optimising structural layouts and material specifications, we help our clients achieve their budgetary goals.
