Constructing a home extension is a great way to add value to your property, while also creating some extra needed space without going through the hassle of moving. Remember that if you’re planning a home extension, you’ll need to hire an architect. But how much does an architect cost for an extension?

Although there is no simple answer to how much an architect might cost for an extension, the fees will vary depending on the size and complexity of your project. As a guide, you can expect to pay a percentage of the total project cost for architectural services. This percentage will also depend on key factors surrounding the project, but you can expect it to be anywhere from 5-15% percent.

Of course, the actual cost will depend heavily on your unique project details. To get an accurate estimate of what you can expect to pay, it’s best to sit down with a few different architects and get a few written quotes. This way, you can compare price structures and find the perfect architect for your project.

What Can Impact TheThe Cost Of Hiring An Architect For Your Extension?

As mentioned there are a handful of factors that can affect the cost of hiring an architect for an extension. Below are listed some of the most common factors that can impact the cost of your project.


  1. The Size & Scope Of Your Project

As mentioned previously when determining how much an architect will cost for an extension, will largely depend on the size and scope of your project. One reason for this is the size of your extension will dictate the number of people working on it. A single architect may be able to complete a smaller project, while a team of architects may be required to complete a large-scale project. Larger extensions will also require extra materials and can even require additional planning permissions.

Due to the various factors that can impact the cost of an architect for an extension, it’s best to consider the size of your project and fees in terms of percentages. For a simpler, small extension, you can expect to pay anywhere around 5-10% of the total building cost, whereas, for a larger, more complex project, you might pay closer to 10-15%.

In general, the size and scope of your project will be the biggest determining factor in how much an architect will cost for an extension. However, there are a number of ways to keep costs down, such as partnering with a smaller architect or limiting the size of your project. With this in mind, before you begin any planning, be sure to establish a budget and what you hope to achieve. You can start searching for an architect who can help make your vision a reality. Ask for a few quotes and be sure that you’re getting the best value for your money.


  1. The Location Of Your Property & Extension

The location of your extension will also be a big factor in the cost of your architect. When building in a more urban area, you are more likely to have to deal with more red tape than if you’re building in an open rural space. This might mean more planning permissions and legal requirements before construction. Because of these conditions, an architect’s fee might be higher in a major metropolitan area rather than in a smaller town. Because urban areas often have more competition among architects, costs associated with running a practice are typically higher in cities, also impacting the cost of your architect and extension project.

Hiring a skilled architect will give you the opportunity to save a considerable amount of time and money when it comes to designing and planning your extension, ensuring that your extension meets all the necessary building regulations and doesn’t come with any surprises. With this in mind, it’s essential to be realistic about your budget and hire an architect from the very start, so that you can ensure your project doesn’t end up costing more than you can afford.

  1. The Complexity Of Your Design


The cost of an architect for an extension will depend on the complexity of your design. If you are considering a more simple design, then the cost will be less than if you have a more complicated design.

A simple rectangular extension will be less expensive to design than a complex addition with multiple angles or curved walls. A small project can also be completed with a few basic drawing tools, while a complex project may require specialised software and equipment. Because of this, if you have a unique vision for your extension and want it to stand out from the norm, always expect to pay more for the architects’ services.

The average cost for planning drawings and fees for an extension will always vary. Luckily the architects at Happinest can provide you with in-depth planning details, allowing you to get accurate quotations for your home extension.
