Last updated: January 31, 2026

If you’re looking for a practical and stylish way to expand your living space outdoors, you’ve probably come across two popular options: log cabins and insulated garden rooms. While they share some similarities, they offer different benefits depending on your budget, usage, and comfort requirements.

Can a Log Cabin Be a Garden Room?

Technically, yes, a log cabin can be a type of garden room. Many people use log cabins as studios, workshops, or even garden offices.

However, most log cabins rely on timber thickness alone for insulation. This can provide some thermal protection, especially in thicker models (like 44mm log cabins). Yet, it’s not quite enough for year-round comfort unless you make upgrades, such as heating, through the winter.

Our models are available in several thickness options. Have a look and see what suits you:

How Well-Insulated Are Log Cabins?

Log cabins can vary greatly in their thermal performance. Here’s what to consider:

  • Timber thickness: Thicker logs (e.g. 44mm or more) offer better natural insulation and help retain heat.
  • Double glazing upgrades: Especially if you opt for uPVC double-glazed windows and doors, you’ll get a significant boost in heat loss.
  • DIY insulation: You can retrofit a log cabin with floor, wall, and roof insulation. However, modifying the structure could void the manufacturer’s warranty—something to be aware of before making alterations.

Log cabins are best for hobbies, workshops, and daytime use. Learn more:

What Makes Insulated Garden Rooms Different?

Insulated garden rooms are designed from the ground up to be fully thermally efficient. They typically use materials like structurally insulated panels (SIPs), which offer excellent insulation built into the walls, floor, and roof.

They often include:

  • Insulation (like EPS foam) inside the roof, floor and walls
  • Double-glazed windows by default
  • Total wall thickness over 60mm

With no need for modifications or upgrades, they’re ideal for creating a true extension of your home in your garden.

Insulated rooms are best for a full-time garden office, year-round use, and evening activities.

Cost vs Comfort: What’s Worth It for You?

If you’re weighing up the options, the key consideration is how often and when you’ll be using the space.

Choose a log cabin if you want a more affordable building for hobbies, storage, or daytime use. Comfort can always be improved later, but going insulated from the start saves time and extra work down the line.

An insulated garden room suits year-round use from day one, with a faster install and no extra work to get it comfortable. It also opens up more design options, rather than limiting you to a traditional log cabin style.

A good example of this is our BillyOh Dojo E Insulated Building.
