Choosing an architect is not just about getting drawings.
For most homeowners, an extension, loft conversion, remodel, or new layout is one of the biggest investments they will ever make in their home. The total cost of the project can quickly run into the tens, or even hundreds, of thousands of pounds.
So it is completely understandable that when people start comparing architectural quotes, they look at the price first. But this is where many homeowners make their first mistake.
The cheapest architect is not always the cheapest option in the long run. Choosing the wrong architect can create problems later during planning, building regulations, structural design, builder pricing, and the build itself. What looks like a saving at the start can become extra costs, delays, compromises, or stress further down the line.
A good architect should help you reduce risk, make informed decisions, and create a design that works not just on paper, but in real life.
1. Have you worked with my local council before?
This is one of the most important questions you can ask.
Planning rules are not the same everywhere. Even if two houses are only a short distance apart, they may fall under different local authorities, different planning policies, or different supplementary planning guidance. That means what is acceptable for one property may not be acceptable for another.
A good architect will understand that planning is not “just a drawing”. They will consider the local council’s policies, previous decisions, neighbouring properties, design context, overlooking, light, scale, character, and the likelihood of approval.
Ask your architect:
Have you worked with this council before, and do you understand their local planning guidance?
An architect with local planning experience is better placed to design something that gives you the best chance of approval while still advocating for what you actually want.
2. What am I really paying for?
Many homeowners look at an architectural quote and think: “Why is this so expensive? Is it not just some drawings?”
That is a fair question. But the value of a good architect is not just in producing drawings. You are paying for judgement, experience, technical knowledge, planning strategy, design thinking, and risk reduction.
A good architect should understand how to balance what you want with what the council is likely to accept. They should know how to design within planning constraints, how to avoid obvious objections, and how to present the proposal clearly.
You are not paying for “some plans”. You are paying for the experience needed to get those plans right.
3. Can you guarantee planning approval?
No honest architect should guarantee planning approval.
The final decision is made by the local planning authority, not the architect. Any architect who promises approval without qualification should make you cautious.
However, a good architect should be able to explain how they will improve the probability of approval. They should be able to talk you through:
- the likely planning risks
- the relevant local policies
- the scale and appearance of the proposal
- neighbouring impact
- previous decisions in the area
- what the council may object to
- how the design can be adjusted to improve its chances
The goal is not blind optimism. The goal is informed confidence.
4. What risks do you see with my project?
This is a powerful question because it tells you how honest and experienced the architect is.
A good architect should not simply tell you what you want to hear. They should be able to identify risks early, such as:
- an extension that may be too deep
- a design that could affect a neighbour’s light
- a property in a sensitive planning area
- strict local design guidance
- building regulations that may affect the layout
- structural requirements that could increase costs
- drainage or access issues that need further consideration
- a budget that may not match the brief
You want an architect who can spot problems before they become expensive. The wrong time to discover an issue is halfway through the build.
5. What happens after planning?
Many homeowners focus heavily on planning permission, but planning is only one stage of the journey.
After planning, you may still need:
- building regulations drawings
- structural calculations
- drainage details
- party wall matters
- builder quotes
- specification decisions
- construction details
- building control approval
This is where “cheap drawings” can become expensive. Ask whether the drawings are suitable for the next stage, or whether they are only for planning.
6. How do you help control hidden costs?
Every homeowner worries about cost. That is normal.
But the architectural fee is only one part of the wider project. The bigger financial risk is often the cost of mistakes, missing details, poor coordination, unclear builder pricing, planning problems, and late changes.
A good architect should explain:
- what their fee includes
- what is excluded
- what other consultants may be needed
- when structural calculations may be required
- when building regulations apply
- whether planning fees are separate
- whether surveys are included
- what could increase the cost later
A better question than “Who is cheapest?” is: “Which option gives me the clearest path from idea to build?”
7. How long will the process realistically take?
Timelines matter, especially if you are planning around family life, finances, builders, or a future move.
For a typical residential project, the process may include an initial consultation, measured survey, concept design, design revisions, planning preparation, planning submission, the council decision period, building regulations drawings, structural calculations, builder pricing, and construction preparation.
Some of these stages are within the architect’s control. Others are not. Ask for a realistic timeline from the first conversation to being ready to build.
8. How will you design for the long-term value of my home?
A good project should not only solve today’s problem. It should also improve the long-term value, usability, and enjoyment of the property.
For many families, the reason for extending is not just “more space”. It is about creating a home that works better, whether that means a larger kitchen, better family space, extra bedrooms, a more practical layout, improved natural light, better connection to the garden, or space for children as they grow.
Ask how the design will improve the way you live in the home and how it could support the property’s value long term.
9. How do you manage the project and communicate with us?
A common source of stress is poor communication. Homeowners often feel unsure about what is happening, what they need to do next, or who is responsible for what.
Before hiring an architect, ask:
- who your main point of contact will be
- how often you will receive updates
- how design revisions are handled
- what happens if the council asks for changes
- how documents are shared
- what information you need to provide
- what decisions you need to make
A good architect should make the process feel clearer, not more confusing.
10. Why should I choose you over a cheaper option?
This may feel like a blunt question, but it is a useful one.
A good architecture firm should be able to explain its value clearly. The answer should not simply be “we are better designers”. It should explain how the firm reduces risk, supports planning success, thinks ahead to building regulations, understands local councils, communicates clearly, and protects the homeowner from costly mistakes.
You should not choose an architect purely because they are the cheapest. You should choose the architect who gives you the most confidence that your project will be handled properly.
Final thoughts
Before hiring an architect, do not just ask: “How much are your drawings?”
Ask about planning risk. Ask about local council experience. Ask what happens after planning. Ask what is included. Ask what could go wrong. Ask how they will protect you from hidden costs.
A home extension or renovation is a major investment. The goal is not to find the cheapest drawings. The goal is to create the right design, avoid unnecessary problems, and make sure the project has the best chance of success.
