How Much is a Log Cabin?

1-sanHow long is a piece of string…?

Without stating the blimming obvious, it stands to reason that the bigger the log cabin and the thicker the log walls, the more expensive it will be.

To help narrow down the multitude of log cabins to choose from, first things first:

  • What are you going to use it for?
  • Do you want to use it throughout the year?

This will give you a good starting point for your budget:

  • Size
  • Cladding (log) thickness – the thicker the log the more heat efficient it will be for year round use

Once you have decided on your cabin, there are plenty of additional extras to consider that will increase the size of your budget as much or as little as you want:

  • Insulation
  • Glazing
  • Roofing
  • Heating
  • Electricity
  • Installation
  • Treatment

Size and Cladding Options

Rule of thumb is if you’re going to use your log cabin throughout the year, you’ll want thicker cladding to help with heat retention. If you’re only going to use it in the summer, thinner cladding would be suitable.

Additional Extras:


Floor and roof insulation kits are available and are very often an optional extra when buying a cabin – Lasita Maja log cabins come with this option.

Prices start from about £500 depending on the cabin.


Single- or double-glazing? The more you use the cabin, and especially if you are going to use it in the winter, will be the deciding factor in what glazing you choose.

A lot of cabins are supplied with double glazing as standard and this is included in the overall price.

However, the Mercia range of cabins, for example, give you the choice of single and double glazing with a difference in price, on average, of between about £100 and £200 depending on the cabin.


Making the right choice is paramount and there’s no point in investing time and money in the perfect log cabin if it isn’t properly protected by the roof covering.

A majority of cabins come with roofing felt as standard with the option to upgrade. It is worth considering spending that little bit more on a cost-effective covering that won’t need replacing regularly.

Most common roofing options:

  • Roofing felt – cheapest option – life expectancy 5 years
  • Bitumen felt shingles – life expectancy 15-20 years
  • EPDM rubber roofing – most expensive option but most cost effective – life expectancy 30-50 years

For some added warmth and cosiness it’s worth thinking about

  • Adding underlay and carpeting
  • Curtains to keep any draughts at bay

Essential if you are wanting heating and lighting.

This will involve running a power cable from your house to the cabin. Plan what you want to power in your cabin and consult an approved electrician for a quote.


If you’re a whizz with DIY and fancy the challenge of erecting the cabin yourself this will save you some pennies.

However, the easier – and, most likely, less stressful – option may be to get a professional in to do it for you. Prices will vary depending on the size and compexity of the cabin.

Very often the cabin suppliers offer an installation service.

Mercia are one supplier that offer this with their cabins. To give you an idea of what an installation might cost:

Mercia Corner Lodge Grande Log Cabin 5m x 3m 28mm (listed above) – Installation  £979

Bear in mind the cabin needs to be constructed on a level and firm base, ie. concrete or garden slabs, so factor in the cost of laying a suitable base if need be.


This is a must. It’s really important to do what you can to give the log cabin the best, and longest, life possible by treating it, firstly with wood preservative, and then 2-3 coats of good quality paint or stain.

So this is another financial consideration to take into account shortly after the cabin’s installation. And regularly, every couple of years thereafter, to strengthen it against the weather.

Have a look at my blog How to Treat a Log Cabin for advice on this.

So, in a nutshell, you can choose from cost-effective log cabins that provide a great space to relax in during the summer months or, if you want a premium cabin built from thicker logs with insulation for use all year, this will cost you more.
