Best Architects in Cardiff: Boutique Firms to Know
Finding the right architect can make a significant difference to the success of a building project. Whether you're planning a home extension, renovating an existing property, creating a new-build home or developing a commercial space, the right architectural practice can help turn an initial idea into a well-considered, practical design.
Cardiff is home to a range of established and independent boutique architectural practices, each with its own approach, specialisms and portfolio. In this guide, we've highlighted practices worth considering if you're looking for the best architects in Cardiff.
Rather than ranking them purely from first to last, we've looked at what makes each practice distinctive, the types of projects they work on and the kind of client or project they may be particularly suited to.
Residential house extension by Dennis Hellyar Architects
1. Dennis Hellyar Architects
Dennis Hellyar Architects is an established boutique architectural practice with a portfolio spanning residential and commercial.
For homeowners, the practice is worth considering when looking for an architect to help develop an existing property or create a bespoke new space. Their work demonstrates an emphasis on creating designs that respond to the requirements of the individual project rather than applying a one-size-fits-all approach.
Residential architecture can involve considerably more than simply producing drawings. An architect needs to understand how a property is used, how the proposed changes will interact with the existing building and how the design can work within practical constraints. This makes experience with a variety of residential projects particularly valuable which makes it one of the best architects in Cardiff.
Why consider Dennis Hellyar Architects?
Experience across architectural projects
Suitable for clients looking for a tailored design approach
Experience across residential and commercial work
A useful option for homeowners exploring extensions, alterations or new-build opportunities
Consideration of materials, context and the character of a building
Award-winning architecture firm

2. 3one3
3one3 is a Cardiff-based architectural practice with a contemporary approach to design. The practice works across residential and commercial architecture, making it an option for clients looking for a practice capable of working on projects beyond the traditional home extension.
One of the important considerations when choosing an architect is whether their previous work aligns with the ambitions of your own project. A portfolio that demonstrates experience across different scales and building types can provide useful insight into how a practice approaches design challenges.
Why consider 3one3?
Experience across residential and commercial work
Contemporary design approach
Suitable for projects where design and functionality need to work together
3. Hyde + Hyde Architects
Hyde + Hyde Architects is a design-led architectural practice known for its distinctive approach to architecture. The practice's work places a strong emphasis on design quality and the relationship between buildings, materials and their surroundings.
For clients looking for something more individual than a standard extension or conventional new-build, this type of design-led practice can be particularly appealing. Architecture is often about finding opportunities within the constraints of a site, and a strong design approach can help transform those constraints into part of the character of the finished project.
Hyde + Hyde's portfolio is therefore worth exploring for anyone interested in architecture with a strong visual identity and a considered approach to materials and context.

Strong design-led approach
Distinctive architectural work

4. Rowlands Architecture
Rowlands Architecture is another practice to consider when searching for an architect in Cardiff. Its work encompasses residential architecture and projects involving the alteration and development of existing buildings.
Working with an existing property can present a different set of challenges from designing a building from scratch. The architect needs to understand the character and limitations of the existing structure while identifying opportunities to improve the way the property looks, feels and functions.
For homeowners considering a renovation, extension or residential alteration, Rowlands Architecture is therefore worth adding to the shortlist.
Why consider Rowlands Architecture?
Residential architectural experience
Suitable for alterations and renovations
Designs that respond to the existing property and its surroundings
A considered approach to residential projects
What To Look for When Choosing Between the Best Architects in Cardiff
Once you've identified several practices that appear suitable, the next step is to compare them against your particular project.
Look at their portfolio
A firm's previous work is one of the best ways to understand its design approach. Look for projects that are similar to yours in terms of property type, scale and ambition.
If you're planning a contemporary extension, for example, look for evidence that the architect has successfully integrated modern additions with existing buildings. If you're considering a new-build home, look at their experience designing from scratch.
Consider their experience with your type of project
Not every architect specialises in the same type of work. Some practices may focus heavily on residential projects, while others have substantial commercial or larger-scale experience.
Think about what you actually need before approaching practices. A clear project brief makes it easier for an architect to tell you whether they're the right fit.
Think about design style
You don't necessarily need an architect whose work looks exactly like your ideal home. However, their portfolio should demonstrate that they understand the type of architecture you're interested in.
Look at how they use:
Materials
Natural light
Space
Form
Existing structures
Landscaping and surroundings
Internal and external connections
Compare the services offered
Architectural services can cover different stages of a project. Depending on the practice and your requirements, these may include initial feasibility work, concept design, planning drawings, technical drawings and assistance through construction.
Before appointing a practice, establish exactly what is included in its service and what additional consultants or professionals you may need.
Consider the size and approach of the practice
Another factor worth considering is whether you would prefer to work with a boutique architectural practice or a larger firm. All of the firms listed above are boutique.
Boutique practices are often characterised by smaller teams, a more personal service and a high level of involvement from senior architects throughout the project. For homeowners and clients undertaking bespoke residential work, this can provide a more collaborative experience, with greater continuity from the initial concept through to completion.
Larger practices may offer broader resources and experience across more extensive or complex projects, particularly in commercial or multi-disciplinary sectors. However, for many residential projects, clients value the direct relationship and tailored approach that a smaller practice can provide.
Neither model is inherently better; the right choice depends on the nature of your project and how you prefer to work. If personal communication, design collaboration and close involvement from the lead architect are important to you, a boutique practice may be particularly appealing.
How Much Does an Architect Cost in Cardiff?
There isn't a single standard price for architectural services in Cardiff. Fees can vary significantly depending on the size, complexity and value of the project, as well as the level of service required.
Architects may charge using different fee structures, including:
Fixed fees
Percentage-based fees
Hourly rates
A combination of different approaches
A straightforward residential project requiring planning drawings is likely to involve a very different level of work from a large new-build development requiring extensive technical design and project management.
When comparing quotations, don't look solely at the headline price. Check what each architect's fee actually covers and whether additional services or consultants will be required.
What Does an Architect Do?
An architect can potentially be involved throughout much of the process of developing a building project.
Depending on the scope of the appointment, this may include:
Initial consultation
Discussing your requirements, budget, property and ambitions for the project.
Feasibility and concept design
Exploring what could be achieved and developing the initial design.
Planning
Preparing drawings and documentation required for a planning application where planning permission is needed.
Technical design
Developing the detailed information required to turn the design into a buildable project.
Tendering
Helping you obtain and assess quotations from contractors.
Construction
Depending on the appointment, the architect may remain involved during construction and carry out site inspections or administer aspects of the building contract.
Not every architectural practice provides every stage, so it's important to establish the scope of services before work begins.
How to Find the Best Architect in Cardiff for Your Project
The practices featured in this guide each offer something different, which is why comparing them by project type and design approach can be more useful than simply looking for a single "best" architect.
If you're considering a residential project, start by looking at each firm's portfolio and identifying examples that are comparable to what you want to achieve. Consider the scale of the work, the design style and whether the architect has experience with the type of property you own.
It's also worth speaking to more than one practice. An initial conversation can give you a better sense of how they approach your ideas, whether they understand your objectives and whether their services are appropriate for the project.
Final Thoughts
Choosing between the best architects in Cardiff ultimately comes down to finding the practice that best matches your project, priorities and budget.
Each firm provides different approaches to architectural design, making them worthwhile starting points for anyone researching architectural practices in Cardiff.
Before making a decision, take the time to explore each firm's portfolio, understand its areas of experience and establish exactly what is included in its architectural service. The right practice should not only be capable of producing a strong design but should also understand your requirements and help guide your project from initial concept towards completion.
