Architect Fees in Northern Ireland

How Much Does an Architect Cost?

One of the most common questions homeowners ask when planning a new house or extension is: how much does an architect cost in Northern Ireland?

Architectural fees can vary depending on the size and complexity of the project, the level of service required, and how involved the architect is throughout the design and construction process.

Our aim is to provide clear and transparent fees, while delivering thoughtful design that creates a home that is beautiful, practical, and energy efficient.

What Services Does an Architect Provide?

Architectural services can range from early concept design to full involvement during construction. We tailor our service to suit each client and project.

Full Architectural Service

A full architectural service usually includes:

  • Initial consultation and briefing

  • Concept and design development

  • Planning application drawings and submission

  • Building Regulations drawings and technical design

  • Detailed construction drawings and schedules

  • Assistance with contractor tendering

  • Site visits during construction

This service supports your project from the first idea through to completion on site.

Typical Architect Fees in Northern Ireland

Architects usually calculate their fees using one of three methods.

Percentage of Construction Cost

The most common approach is a percentage fee based on the construction cost. This reflects the level of work involved in designing the building and supporting the project during construction.

For residential projects, architectural fees across the UK and Ireland often fall within a range of approximately 7 percent to 15 percent, depending on the scope of services provided.

Fixed or Lump Sum Fees

For clearly defined stages of work, such as concept design or planning drawings, a fixed fee may be agreed. Many clients prefer this because it provides certainty about the cost of the work.

Hourly Rate

Some services, such as consultations, feasibility studies, or additional design work, may occasionally be charged on an hourly basis.

Our Approach to Architectural Fees

For most residential projects we use a two stage fee structure.

Early stages of the project are usually agreed as fixed fees, which helps provide cost certainty while the design is being explored and developed.

Once the design is established and construction costs become clearer, the fee may transition to a percentage of the build cost.

This approach balances cost certainty in the early design stages with fairness once the final scope of the project is known.

Each project is priced individually based on:

  • The size and complexity of the project

  • The site and planning context

  • The level of architectural service required

  • The anticipated construction budget

We typically work on residential projects with construction budgets ranging from £150,000 to £2 million.

Energy Efficient and Passivhaus Design

Energy efficiency is an important part of modern home design. We can provide Passivhaus design support and thermal modelling, including PHPP energy calculations.

This allows us to analyse how a house will perform before it is built, helping to:

  • Reduce heating demand

  • Optimise insulation levels

  • Improve internal comfort

  • Reduce the risk of overheating

For existing homes we can also advise on energy retrofit strategies, helping homeowners improve comfort and reduce running costs.

Extensions & Renovations

We also work on home extensions, renovations, and upgrades to existing houses.

Older buildings often require a careful approach to ensure that improvements to insulation and energy performance do not damage the structure or character of the building.

Final Few Thoughts

The Architectural Design Process

Every project begins with an initial consultation, either in person or online. This meeting allows us to understand your brief, priorities, and ideas for your home.

As the design develops we produce drawings, sketches, and 3D models so that you can clearly visualise the proposals. The process is collaborative, with regular meetings to review ideas and refine the design.

Once the design is sufficiently developed, a Quantity Surveyor may provide cost advice so that the project remains aligned with your budget before construction begins.

Transparent Fees and Clear Proposals

We structure our fees in stage payments, linked to the progress of the project. This spreads the cost and ensures you only pay for services as they are delivered.

Before starting any work we provide a clear written fee proposal outlining:

  • The services included

  • The architectural fee structure

  • Any additional costs you may need to allow for, such as planning fees or specialist consultants

This helps give clients confidence and clarity from the outset.
