Garden Outhouses

Modern Garden Outhouses Designed as Proper Usable Rooms

The term garden outhouse is used in different ways.

​

Historically, an outhouse could mean a simple detached external building, and in some contexts the word was also associated with an outside toilet.

​

Today, many homeowners use the term much more broadly to describe a detached building within the garden.

​

That could mean:

  • garden office

  • studio

  • gym

  • hobby room

  • garden bar

  • storage building

  • workshop

  • guest room

  • entertainment room

  • general purpose garden room

​

In practical terms, a modern garden outhouse can be designed and built in exactly the same way as a contemporary garden room.

​

​

What Is a Garden Outhouse?

 

A garden outhouse is simply a detached building positioned within the garden or curtilage of a property.

​

The term is especially common among homeowners who may also use phrases such as:

  • garden building

  • garden house

  • garden shed

  • garden room

  • garden studio

  • outside room

​

The actual design and specification matter much more than the label.

​

A simple uninsulated shed and a fully finished garden office can both technically be described as outbuildings, but they are very different buildings.

​

​

Garden Outhouse Versus Garden Room

 

The terms often overlap.

​

A modern garden room is usually designed for people to spend significant time inside it.

​

That normally means consideration of:

  • insulation

  • glazing

  • heating

  • electrics

  • ventilation

  • internal finishes

  • comfort

​

A traditional outhouse may have been much more basic.

​

Today, however, many people searching for garden outhouse are clearly looking for a proper usable garden building rather than a basic shed.

​

​

Insulated Garden Outhouse

 

An insulated garden outhouse can be used throughout much more of the year.

​

Typical uses include:

  • home office

  • studio

  • gym

  • music room

  • games room

  • hobby room

  • garden bar

  • leisure room

​

A properly insulated building should consider the floor, walls and roof together.

​

Glazing, airtightness and ventilation also play an important part.

​

​

Small Garden Outhouse

 

A small garden outhouse can provide useful additional space without taking over the garden.

​

Compact designs can work well as:

  • single person office

  • study

  • reading room

  • hobby room

  • small studio

  • storage room

​

The key is to make the layout work efficiently.

​

In smaller buildings, door positions, glazing and furniture need to be carefully considered.

​

​

Large Garden Outhouse

 

A larger garden outhouse gives much more flexibility.

​

It can potentially combine several functions, such as:

  • office and gym

  • studio and storage

  • lounge and bar

  • hobby room and workshop

  • garden room and shed

  • entertainment room and outdoor kitchen

​

This is where proper plans become especially valuable.

​

​

Wooden Garden Outhouse

 

Timber construction is particularly popular for garden buildings.

​

A timber framed outhouse can offer:

  • fast construction

  • good insulation

  • design flexibility

  • lightweight structure

  • wide choice of cladding

​

The exterior can be finished in:

  • cedar

  • larch

  • thermowood

  • composite

  • painted timber

  • vertical cladding

  • horizontal cladding

​

The appearance can therefore range from traditional to highly contemporary.

​

​

Outhouse Sheds

 

Some searches for outhouses are really looking for sheds.

​

A shed is normally designed primarily for storage.

​

A garden room or insulated outhouse is generally intended for people to occupy for longer periods.

​

The difference may include:

  • insulation

  • heating

  • internal lining

  • better glazing

  • electrics

  • finished flooring

  • ventilation

​

For some homeowners, the best solution is to combine both.

​

​

Garden Outhouse With Storage

 

A modern garden outhouse can include a separate storage section.

​

For example:

Office + shed

​

or

Studio + storage

​

or

Gym + bike store

​

The storage section can be simpler internally while the main room is fully insulated and finished.

​

This can be a very efficient way to replace both a shed and a garden room with one coordinated building.

Garden Outhouse as a Home Office


A detached garden office is one of the most popular uses.
 

It creates a clear separation between home and work while keeping the commute to a few steps across the garden.
 

A good office design should consider:

  • desk position

  • natural light

  • electrical sockets

  • internet

  • heating

  • storage

  • privacy

  • ventilation

     

Garden Outhouse as a Studio


Studios can be designed for:

  • art

  • photography

  • craft

  • music

  • design

  • content creation
     

The layout should reflect the activity.
 

An art studio may need more wall space and natural light.
 

A music room may need acoustic treatment.
 

A photography studio may need a larger uninterrupted area.

 

Garden Outhouse as a Gym


A garden gym can provide a dedicated exercise space without taking over a bedroom or garage.
 

It can include:

  • cardio equipment

  • free weights

  • mirrors

  • storage

  • ventilation

  • air conditioning

  • shower room
     

Floor structure and headroom should be considered carefully.

 

Garden Outhouse as an Entertainment Room


A larger outhouse can also become a leisure or entertainment space.
 

Possible uses include:

  • cinema room

  • garden bar

  • games room

  • family room

  • lounge

  • music room
     

Large glazing can help connect the room to the garden.

 

Planning Permission for a Garden Outhouse


A garden outhouse may potentially fall within Permitted Development rights if the relevant conditions are met.
 

These can include:

  • position

  • height

  • distance from boundaries

  • overall garden coverage

  • property type

  • intended use
     

The name of the building does not affect the planning rules.
 

Calling something an outhouse rather than a garden room does not change how it is assessed.

 

Building Regulations


Building Regulations are separate from planning permission.
 

Whether approval is required can depend on:

  • floor area

  • distance from boundaries

  • use

  • sleeping accommodation

  • construction

  • services
     

A small detached building may be exempt in some circumstances, while a larger or more complex garden room may need approval.

 

Garden Outhouse Cost


The cost will depend on:

  • size

  • foundations

  • insulation

  • cladding

  • glazing

  • roof

  • electrics

  • heating

  • internal finish

  • plumbing

  • access
     

A basic storage building can be relatively inexpensive.
 

A fully insulated, highly glazed garden room can cost significantly more.
 

The specification matters far more than the label.

 

Building an Outhouse in the Garden


Before construction begins, decide:

  • what the building will be used for

  • how large it needs to be

  • where it should sit

  • whether planning permission is required

  • whether Building Regulations apply

  • what foundation system is suitable

  • how electricity and drainage will reach it
     

The earlier these decisions are made, the easier the build becomes.

 

Garden Outhouse Plans


Proper plans can help coordinate:

  • footprint

  • floor layout

  • doors

  • windows

  • roof

  • foundations

  • wall construction

  • insulation

  • electrics

  • storage

  • services
     

They also give builders something definite to price.
 

This can make comparing quotations much easier.

 

Adapt an APN Garden Room Design


If you are searching for a garden outhouse, you do not need to start with a blank sheet.
 

Many APN Garden Room designs can be adapted to suit your needs.
 

Possible changes include:

  • altering the size

  • changing the glazing

  • adding storage

  • adding a WC or shower

  • creating an office

  • creating a studio

  • changing cladding

  • adding a canopy

  • creating an L shaped design
     

You start with a professional design and then adapt it around your garden and intended use.

 

Potential Savings of 40 to 50%


Depending on the design, location, specification and how the project is managed, it may be possible to reduce the overall cost by around 40 to 50% compared with some equivalent turnkey garden room packages.
 

The aim is not to build a cheaper room.
 

It is to spend more of your budget on the room itself and less on the layers surrounding it.
 

That could mean:

  • better glazing

  • better insulation

  • better cladding

  • better internal finishes

  • a larger room

  • more money left for landscaping or furniture

     

Start With the Design


The first step is choosing the right garden room.
 

From there, you can:

  • use the design as shown

  • adapt it to suit your garden

  • obtain planning advice if required

  • add Building Regulations information where needed

  • request builder quotations

  • source products and materials

  • control the final build cost
     

Choose the design. Control the build. Keep more of the budget.
