Paddick Engineering is a family-owned architectural, civil, and structural engineering design consultancy based in Leeds, West Yorkshire. Founded in 1981 and with over 45 years of continuous trading, the firm offers a comprehensive design package covering everything from planning drawings and structural calculations through to drainage design, flood risk assessments, and project management, all under one roof.
🧩 What Does an Architect or Structural Engineer Actually Do?
An architect is responsible for the visual and functional design of a building, translating your ideas into detailed drawings that show what a finished structure will look like, how it will be laid out, and how it will meet planning requirements. A structural engineer, on the other hand, focuses on the bones of the building: the beams, columns, foundations, and load-bearing walls that keep everything standing safely. Both disciplines are essential, but they approach a project from different angles.
On a typical home extension or new build, the two roles work closely together. The architect produces planning drawings and building control drawings that describe the design intent, while the structural engineer provides the calculations and technical specifications that prove the structure is safe and compliant. Think of it as the architect designing the dream and the structural engineer making sure it stays up.
Hiring a firm that brings both disciplines together under one roof, as Paddick Engineering does, removes the coordination headaches that arise when you appoint separate consultants. There is no risk of conflicting advice, no time lost chasing two different parties, and no duplication of fees. One experienced team holds the full picture from day one.
🧩 What to Look for When Choosing Leeds Architects or Engineers
The title ‘architect’ is not the only route to high quality building design. There are many experienced Architectural Designers and Architectural Technologists who are fully capable of delivering excellent work across a wide range of project types. Architectural Technologists may hold membership of the Chartered Institute of Architectural Technologists (CIAT), and bring particular strength in the technical and construction detailing aspects of a project. What matters most is relevant experience, a strong portfolio, and a clear understanding of the planning and building control process, not the specific title on the business card.
For structural engineers, membership of the Institution of Civil Engineers (ICE) or the Institution of Structural Engineers (IStructE) is the recognised benchmark.
Beyond credentials, ask how long the practice has been established, what types of projects they regularly deliver, and whether they have direct experience working with the local planning authorities across West Yorkshire. Before commissioning anyone, request examples of comparable completed projects, clarify who your day-to-day contact will be, and establish exactly what is, and is not, included within the fee. A clear, confident answer to each of these questions is a good indicator of a professional operation.
Common warning signs of less scrupulous operators include demands for large upfront cash payments, an inability to provide references or evidence of insurance, poorly defined written agreements, and reluctance to engage with formal planning or building control processes. Verifying credentials, seeking out genuine reviews, and ensuring everything is confirmed in writing remain the most reliable safeguards.
Local knowledge also carries more weight than is often appreciated. Planning policy can differ considerably between Leeds City Council, Bradford Council, and Kirklees, understanding the specific expectations of the relevant authority from the outset saves time and reduces the risk of a refused application.

🧱 The Full Range of Building Design Services You May Need
A comprehensive design project typically begins with planning drawings, the architectural plans, elevations, and supporting documents that you submit to your local planning authority for approval. Once planning consent is granted, the process moves on to building control drawings, which are far more detailed and technical, showing precisely how the building will be constructed to satisfy the Building Regulations. Paddick Engineering produces both, so there is no gap between the two stages.
Structural calculations sit alongside the building control drawings and demonstrate to building control that beams, foundations, and structural elements have been properly engineered. For projects on lower lying land or near watercourses, a flood risk assessment may also be required, something Paddick Engineering handles as part of its civil engineering offering. Drainage design is another area that is often overlooked early on but can have a significant bearing on both cost and programme if left too late.
Beyond design and calculations, Paddick Engineering offers a range of survey services including home buyers surveys, structural surveys, and drone surveys, useful for assessing existing buildings, identifying defects before purchase, or capturing detailed site information. For clients who want support beyond the drawing stage, the firm also provides project management and construction consultancy, helping to keep builds on track and on budget from groundbreaking to completion.
💡 Why Paddick Engineering Is a Trusted Name in Leeds & West Yorkshire
Paddick Engineering has been trading continuously since 1981, that is over 45 years of delivering architectural and engineering design across the region.
In 2015 Paddick Engineering were recognised as LABC Partnership Award Winners, an accolade that reflects the firm’s consistent commitment to quality, compliance, and its productive working relationships with local building control authorities. That kind of recognition is hard earned and speaks directly to the reliability that homeowners and developers need from their design consultant.
The firm’s project experience spans residential, commercial, and civil work at all scales, from straightforward single storey extensions right through to larger development schemes. Clients across Leeds, Bradford, Huddersfield, Wakefield, Harrogate, and well beyond have benefited from that breadth of expertise. Whether your project is modest or ambitious, you will be working with a team that has almost certainly seen something similar before.
💡 House Extensions and New Builds: Getting Your Project Started the Right Way
One of the most valuable things a design consultancy can do is engage early. A land appraisal or initial site review carried out before any design work begins can identify constraints, ground conditions, drainage challenges, flood zones, boundary restrictions, or local planning sensitivities, that would otherwise become expensive surprises mid project. Paddick Engineering offers land appraisal services precisely for this reason: early intelligence saves money.
A comprehensive design package, as Paddick Engineering delivers it, typically moves through concept design, planning drawings, structural and civil engineering design, building control drawings, and construction specification, each stage building on the last and informed by the same team throughout. That continuity is genuinely valuable. Instructions do not get lost in translation between separate consultants, and design decisions made at the planning stage are properly carried through into the construction details.
Common mistakes homeowners make when starting a new build or extension project include appointing a builder before the design is complete, underestimating the time the planning process takes, and failing to budget for building control and structural engineering alongside the main construction costs. Paddick Engineering’s approach is to lay all of this out clearly from the outset, so there are no unwelcome surprises. Clear, honest advice at the start of a project is one of the things that 45 years in business teaches you to provide.
Frequently Asked Questions About Leeds Architects and Structural Engineers
The questions below cover the things homeowners and developers most commonly ask when they are starting to think about a project in Leeds or West Yorkshire. If your question is not here, Paddick Engineering is always happy to talk through the specifics of your situation.
Do I need both an architect and a structural engineer for a house extension?
For most extensions, particularly those involving removal of load bearing walls, new beams, or significant foundation work, you will need both architectural drawings and structural engineering input. Architectural drawings are required for planning permission, while structural calculations are typically required for building control approval. Using a firm like Paddick Engineering that provides both means you only ever deal with one team.
What is the difference between planning drawings and building control drawings?
Planning drawings are submitted to your local planning authority and focus on the appearance, scale, and impact of the proposed development. Building control drawings are far more detailed and technical, demonstrating exactly how the structure will be built to comply with the Building Regulations. Both sets of drawings are usually needed before work can start on site.
What does 'cowboy builders' mean and how do I avoid them?
The term refers to unscrupulous contractors who take on work they are unqualified or uninsured to carry out, often delivering poor quality results or disappearing with deposits. Protect yourself by checking qualifications and insurance, asking for written contracts, seeking genuine references, and ensuring all planning and building control processes are followed properly.
How do I find a reliable architect or structural engineer in Leeds?
Look for firms with verifiable credentials, a proven track record of completed projects, and transparent fee structures. A long established, family owned firm with local experience, such as Paddick Engineering, trading since 1981, offers an additional layer of accountability.
What services does a structural engineer provide on a residential project?
On a typical residential project a structural engineer will produce structural calculations, specify beam and foundation sizes, assess load bearing walls, and provide the technical drawings needed for building control approval. They may also carry out structural surveys on existing buildings, advise on drainage, and contribute to flood risk assessments.
How long does the planning and building control process take in West Yorkshire?
A standard householder planning application typically has a target determination period of eight weeks, though complex cases or those requiring consultation can take longer. Building control approval timelines vary depending on whether you use a full plans application (usually four to eight weeks for initial checks) or a building notice route. Your design consultant can advise on the most appropriate approach for your specific project.
Can one firm handle both architectural design and structural engineering?
Yes, and there are real advantages to using one firm for both. Paddick Engineering provides architectural design, structural engineering, civil engineering, drainage design, and a range of survey and consultancy services, meaning your project benefits from joined-up thinking and a single point of contact throughout.
