Garden Room with Side Shed Comparison Guide

Last updated: June 13, 2025

So, you’re looking for a garden room but you want one that’s combined with a shed for convenient storage, so you don’t have to worry about sacrificing shed space when you get your fabulous new garden retreat. Here we are going to compare the different options of log cabin rooms that have integrated storage, as well as models that come with an optional side-store add-on.

Why Choose a Garden Room Shed Combo?

Rather than have to choose between a shed and a log cabin, you can now have both in one. This is a great option for gardens with limited space to spare.

Of course, buying a 2-in-1 building also saves money. Buying a shed separately from a garden room could be a difference of hundreds of pounds.

Another great benefit is how this expands the functionality of the garden room itself. Imagine these scenarios:

  • Use your garden office during the week and then swap furniture from the side store to make it a family relaxation spot at the weekend.
  • Exercise in your garden gym and then put the equipment away in the side shed to make the room free for other activities.
  • Ready for a barbecue party? Put all your seating in the cosy shelter of your log cabin and put everything away in the conveniently located side storage.
  • Busy gardening? Take your tea break right next to the shed where all the tools are kept.
  • Let the kids run wild around the garden while you watch them from the comfort of your log cabin, then put all the toys away… you get the picture.

Types of Garden Room Shed Combos

Let’s start comparing your options:

Log cabins that can fit a lean-to side store

Some of our log cabins have an “Add More Storage” option that means they will come with this lean-to wooden storage unit that fits easily on the side wall.

A side storage shed attached to a garden log cabin

Available in either 19mm or 28mm log walls for greater insulation and weight-bearing capacity, this side shed has a sloped roof that lets rainwater flow away from the main cabin. It measures 1.5×2 metres for compact, private storage, so you would need to make sure you have an extra 1.5m space next to where you plan your log cabin to go. Simply fit a lock and your items are safe.

As with all lean-to buildings, it is designed only for use against a wall, and has fittings specifically for attaching to a wooden log cabin wall. Naturally this means it only comes with 3 walls (as a fourth wall would be redundant and also potentially lead to trapped moisture).

The lean-to log cabin side store is available on our log cabins of these models:

BillyOh Fraya Max Pent Log Cabin

BillyOh Aston Wooden Garage

BillyOh Alpine Log Cabin Workshop

BillyOh Winchester Log Cabin

BillyOh Devon Log Cabin

Garden Room with Integrated Side Shed

You might prefer a garden room that is a little more two-in-one, where the storage is under the same roof rather than looking like a box on the side.

For this, we have the Tianna Log Cabin with Side Store. You can see how there are 3 doors on the front: a pair of fully glazed double doors for the main room section, and a boarded door on the end for access to the shed.

This option leaves you with a larger shed section than the lean-to add-on, as it is as tall as the rest of the building and spans the full depth. Additionally, the partition wall between the sitting room and the side shed can be placed to your liking, to widen the storage area if you need to.

And while this is not considered an insulated garden room, there is also a summerhouse option: our Penton Corner Summerhouse with Side Store is designed to fit in the corner of your garden with diagonal-facing doors for a panoramic view. It has a corner cutoff design for extra space saving. However, a summerhouse of this nature does not stay as warm as a log cabin, so it’s designed more for seasonal use.

Conclusion: Maximise Your Garden Space with a Smart Combo

A garden room shed combo is the ultimate space-saving solution, giving you the best of both worlds. With one of these buildings, you have a relaxing or productive garden retreat and secure, accessible storage right where you need it. Whether you opt for a fully integrated design like the Tianna, or a more flexible layout with a lean-to side store, the result is the same: less compromise, more function.

FAQ

It’s a garden building that combines a usable room (like an office, gym or summerhouse) with a dedicated storage area, either built into the same structure or added via a side store. It saves space, looks stylish, and keeps your garden tidy.

It depends on your space and flexibility needs. A lean-to side store is great for modular layout and adding later. An integrated shed like in the Tianna model offers a unified design and larger enclosed space under one roof.

Our cabins are all within the legal height limits to count as permitted developments, but you still have to make sure you build it within the rest of the rules. For example, it must not take up more than half of your outdoor space. Our guide to log cabin planning permission goes into the full details.

Our standard side stores measure 1.5m wide by 2m deep, so ensure you’ve got at least 1.5m clearance alongside the cabin you plan to attach it to.

Yes! Our side stores are made with durable tongue-and-groove log walls (19mm or 28mm) and are suitable for storing bikes, garden tools, BBQs, or seasonal gear. You can also add a lock for extra security.

Absolutely. The lean-to sheds feature sloped roofs to direct rain away and are designed to be weather-tight when installed against a log cabin. You are required to apply weatherproof treatment and install the building on a suitable base.
