How to Choose an Architect and a Builder for Your Home Project

6 August 2026 12:04

You’re looking to build the dream team for your next home project but don’t know where to start? You’ve come to the right place.

Choosing the right architect and builder for your home can feel overwhelming, especially if it’s your first time. According to the HomeOwners Alliance, 42% of UK homeowners said finding a reliable builder was the main obstacle to home improvements, rising to 53% in London.

For architects, RIBA found only 15% of homeowners rate cost as the most important factor in their choice, with most prioritising professional credentials and references instead – yet knowing what to look for isn’t always straightforward.

Therefore, being well-informed about the hiring process before you start makes all the difference to getting your dream home built without any problems or delays.

In this blog, we walk you through what questions to ask, red flags to avoid, and how to match the right architect and builder to your upcoming project. Whether you’re new to the world of home design or a seasoned professional, you’ll find useful tips and information to help you decide with confidence.

Start With How You Want to Procure the Project, Not Who You Want to Hire

Before making your decision on an architect and builder, you need to think about the size and complexity of your home project. Whether it’s a self-build, extension or house renovation, there are three main routes you can take:

Traditional

Start with the architect who goes through design and planning and produces the full technical drawings for the project. Once complete, you approach builders for quotes. As the homeowner, you coordinate the two separate parties who may or may not have worked together before. Only when the design is finished does the construction start – there is no overlap.

Design and Build

One single contract responsible for both design and build. Sometimes the builder may employ or subcontract the architect themselves, which still means there’s only one point of contact. The most popular route in the UK, as it gives earlier cost certainty and fixed-price agreements. It also speeds things up as the two phases can overlap; however, changes can be harder and more expensive to make.

Architect-led Contract Administration

This route is more of an extension of the traditional route to home projects. Instead of the architect stepping back once the design is complete, the architect takes on the role of administrator during the construction phase. This includes inspecting work, answering site queries, and tracking costs, taking away the accountability from the homeowners and remaining impartial to get the project completed.

Understanding these routes beforehand is important because it will determine who you approach first and how accountability works between you, the architect and the builder.

The traditional route suits projects where design control matters most, for example self-builds, listed buildings or anything architecturally ambitious. The design and build route, however, is more suited to homeowners who don’t mind trading design control for speed and a single point of contact.

Finally, the architect-led contract administrator is for projects that need someone independent to manage quality and payments, which is why it’s important to ask the right questions before you commit.

Getting to know the architect and builder on a deeper level, beyond their portfolio, gives insight into how they will approach your project.

Key Questions To Ask an Architect and Builder Before You Choose

Asking about the architect or builder’s experience isn’t enough when it comes to choosing the right one for your project. You need to dive deeper and ask key questions that reveal how they’ll behave under pressure.

We’ve listed below some key questions for you to ask to help guide you when making your decision. These types of questions aim to establish their working style to see how they work and their approach to different situations that may pop up during the project.

What to Ask an Architect Before You Commit

How do you handle scope or budget changes mid-design?
How involved are you once construction starts?
How have you worked with builders in the past (do you have builders you regularly collaborate with, or is this a first pairing)?

What to Ask a Builder Before You Commit

How do you handle programme slippage?
What does your contingency process look like?
How do you expect to communicate with the architect during the build (site visits, sign-off on changes, who resolves disagreements)?

In your first meeting, it’s great to have these questions on hand to ensure you cover every aspect of the project in as much detail as possible. How they respond will then help you with your decision.

If they are hesitant to answer these types of questions or struggle to answer them, it could be a potential red flag.

Red Flags to Watch Out For in Either Professional

When choosing your architect and builder, it is important to watch out for any red flags. This may be difficult if you’ve never been in this position before, but knowing these ahead of time could potentially save you a lot of time, money, and stress.

See the red flag checklist below for both professionals to help make your decision easier.

Red flags for an architect include not registered with the ARM, slow and vague responses, resistant to put agreements in writing, no portfolio, vague about fees. Red flags for builders include no public liability insurance, reluctant to give a written quote, no portfolio, quote lower than others, no point of contact.

If either professional is slow to respond, avoids communicating about something important, or won’t put anything in writing, you know not to go ahead.

Matching Your Architect and Builder to Your Project Type

Going back to the first point, understanding what you’re building is key to matching your architect and builder to your project.

A straightforward extension may need less architect involvement and a builder confident enough to work from simple drawings. Whereas a listed building or a complete self-build needs both professionals experienced in planning constraints and collaboration.

The important thing to remember is their willingness to work together, transparency in communication, and a commitment to keeping you informed of changes before, during, and after the project.

The best results come from an architect and builder who understand exactly what each other needs. Learn more about the difference between an architect and builder and the key qualities they should possess here.
