Architecture Roles – Who Does What on a Building Project

If you’ve ever wondered why a project team has so many different titles, you’re not alone. From the first sketch to the final handover, each role has a clear purpose. Knowing who does what helps you ask the right questions, avoid costly mix‑ups, and keep the project on track.

Core Architectural Services

The first name you’ll hear is architect. Their job starts with understanding your brief, then turning ideas into drawings that meet planning rules and budget limits. They don’t just produce pretty pictures – they coordinate with engineers, check that the structure will be safe, and make sure the design complies with UK building regulations.

Next up is the designer or interior architect. While the architect focuses on the building’s shape and how it sits on the site, the designer fine‑tunes the interior layout, material choices, and finishes. They bridge the gap between big‑picture design and everyday comfort, making sure rooms flow well and look good.

When the project moves to the planning stage, a planning consultant often steps in. Their expertise lies in navigating the local council’s planning permission process. They know which details need a drawing, what documents the council expects, and how to address objections quickly.

Supporting Roles in the Build Process

A structural engineer follows the architect’s concept and checks that walls, roofs, and foundations can handle real loads. They produce calculations and reinforcement details that the contractor uses on site. Without a solid structural plan, even the best design can collapse.

The project manager or construction manager keeps the timeline moving. They schedule trades, order materials, and watch the budget. Their daily check‑ins catch delays early, so you don’t end up with a half‑finished house.

Don’t forget the quantity surveyor. This person estimates costs, tracks expenses, and advises where you can save without hurting quality. They’re the reason you get a realistic quote before the first brick is laid.

On larger schemes you might also meet a building services engineer. They design heating, ventilation, electrical, and plumbing systems. Their work ensures the building stays comfortable, efficient, and meets regulations for energy use.

Finally, the contractor (sometimes called the builder) turns the plans into reality. They hire subcontractors, manage site safety, and deliver the finished structure. A good contractor respects the architect’s vision while solving practical on‑site challenges.

Understanding each of these roles makes you a better client. You’ll know who to call when a design change comes up, who can advise on cost cuts, and who holds the keys to planning approval. It also helps you spot red flags – like an architect who doesn’t communicate with the engineer or a contractor who skips site meetings.

In short, a building project is a team sport. When every player knows their job, the project stays on budget, meets deadlines, and ends up looking great. Keep this guide handy the next time you start a home extension, garden room, or new build, and you’ll feel more confident navigating the process.
