Adding Value to your Home with a Garden Room


Will a garden room add value to my home? An important question to consider when adding a garden room to your property. Well, the short answer to this question is…YES! 

Garden buildings are a unique and cost-effective space-creating solution that can add appeal and value to your home. But, how much value does a garden room add?

“Yes, there is no doubt that a garden room can add significant value to your property.”

4 reasons why a garden room adds value to your home


1. Increased Floor Space:

Home extensions are huge projects that can be disruptive, overwhelming and cost a fortune. A garden building allows you to add floor space to your home in a quick and hassle-free way. If you’re looking to create a home office, gym or studio then removing a bedroom or other conventional room in the home is not the most appealing way to do it.

Increase your floor plan without the hassle of an extension

A garden building is a completely separate and new space that offers privacy as well as full flexibility to be transformed into anything! Whilst a garden room might not add as much value to your property as a traditional home extension or loft conversion, the value for money vs increased value is often much better than traditional extension alternatives.


“CALA understands that it is increasingly important to have dedicated ‘breakaway’ spaces too, such as lounges for entertaining or unwinding, and home offices for designated work space.”

-Glenn Copper, Sales & Marketing Director, Cala Homes



2. Wow Factor:

Our garden rooms are unique spaces that are a modern and beautiful addition to your home and garden. Having a garden room at your home will create more interest in your property should you come to sell. The higher number of viewings tends to mean a quicker sale, and as a result, the asking price is normally met because potential buyers don’t want to miss out.

Add wow factor to your home

“Now, more than ever, there is a need for these garden rooms and there is absolutely no questioning the fact that these are very desirable features of a home.”
– Robert Ellis | Nutbrook Property.



3. Dedicated Work From Home Space

Having a dedicated office space is fast becoming an essential feature for prospective buyers. “Home offices are mentioned in the majority of our conversations with prospective buyers” reports Luke Jackson from Michael Graham. “Having a home office in the garden away from the house can now make or break a property deal.”

“As many of us are spending much more time at home through home or hybrid working, buyers are now considering in much more detail what they really want and need from their property and truly optimising their space accordingly.”

-Glenn Copper, Sales & Marketing Director, Cala Homes



4. Attract fitness fans or hobbyists:

A garden gym is an investment in your home and health. Fitness-conscious buyers will see the benefit of a dedicated space to focus on their fitness goals, without interrupting (or being interrupted by) other members of their household. 

For hobbyists, having a quiet space away from the home to practise their craft and store their equipment often makes the garden room their favourite room at home!



So, how much value does a garden room add?

Garden rooms can add 1.5x their value to a home depending on the quality of the build, therefore covering the cost of the installation. Luke Jackson at Micheal Graham estate agents has found that “Not only does a garden room attract more buyers to your property, but a high-quality garden room can also boost the value of your home by 5% to 15%”

Robert Ellis of Nutbrook Property said: “I would estimate that the value-added would be about 1.5x the cost of the building installation. The convenience value is also significant and must be considered for homeowners.”

Add value to your home with a garden room

Robert Ellis of Nutbrook Property also says: “Whilst a lot of the value is attributable to the extra space it creates, a garden room is modern and stylish and adds to the whole appeal of the property. There is no doubt that the quality of the building adds significant value too.”

CALA Homes see the value in the space garden rooms provide so much that they’ve begun offering them with home sales.

“At our Cala at Beaulieu development, we’re also offering buyers an additional ‘breakaway’ space with stand-alone Garden Rooms from Green Retreat available to purchase as an upgrade.

These Garden Rooms are offering our buyers at Beaulieu a whole host of extra options, whether it’s used as a home office, a gym, an impressive bar for hosting parties or a quiet snug to get away from it all – a Garden Room can be an exciting additional space to use as your lifestyle requires.”

-Glenn Copper, Sales & Marketing Director, Cala Homes

A poor-quality building is more likely to put off potential buyers, so choosing the right supplier is key. That’s where Green Retreats can help.



Does a Garden Office add value to your home?

Garden Offices have topped the list of Rightmove’s recent analysis of the home features that have grown in popularity. The UK’s biggest property website has seen the proportion of property listings that mention ‘garden offices’ up by 1,046% compared to 10 years ago.

“Agents and developers have their finger on the pulse when it comes to the home features that will attract suitable buyers. Where dining rooms and fitted wardrobes may not be as important to some potential buyers compared with ten years ago, other features like an outdoor office space have soared as working patterns have changed, and the findings indicate a move towards greener features too.

With outside space coming at such a premium, it may be that homeowners are ensuring what they build outside can be used in a number of different ways.”

Property expert Robert Ellis says: “I would estimate that the value-added would be about 1.5x the cost of the building installation. The convenience value is also significant and must be considered for homeowners.”


“Not only does a garden room attract more buyers to your property, but a high-quality garden room can also boost the value of your home by 5% to 15%.” – Luke Jackson, Branch Partner – Michael Graham Buckingham Office.


“For homeowners keen to add more floor space to their property, a garden room is a far less invasive and costly undertaking compared to converting the loft or the garage. Using a company like Green Retreats will make sure that you’re compliant with all local planning regulations and in years to come, if you want to change the use of the room from an office to an annexe for guests, you can be sure that the structure is equally suitable for that purpose.” – Luke Jackson, Branch Partner – Michael Graham Buckingham Office.


Garden rooms generally do not require planning permission.

A garden room is classed as an ‘outbuilding’, and outbuildings are allowed without planning permission because they fall within your permitted development rights. Sometimes certain areas in the country do not allow permitted development, so this could mean that planning permission would be required, but if you do need to apply for planning permission we will take care of the application for you – giving you one less hassle to handle. Find out more about planning permission and permitted development.


A quality built garden room from Green Retreats comes with a comprehensive 10-year guarantee. Our guarantees follow a similar structure to a guarantee that you would receive that any new-build home. The buildings themselves have been designed for a 30-year life span and use materials as standard that are completely maintenance-free.


Luke Jackson at Michael Graham Estate Agents said: “we have experienced first-hand the dramatic effect the pandemic has had on house buyers. Now that working from home is so widespread, lists of priorities have changed and home offices are mentioned in the majority of our conversations with prospective buyers. Having a home office in the garden away from the house can now make or break a property deal. People may not be commuting to the office every day but they still like the structure of leaving the house to go to work. A garden room provides that physical and mental distance between home life and work life.” 

garden office is a fantastic way to use the extra space a garden room provides at your home. Being detached from the main house gives you the perfect privacy to work professionally from home whilst still being able to enjoy the perks of being at home. Garden buildings from Green Retreats are fully-insulated for year-round-use, meaning you can work comfortably from your garden office in even the coldest months. Our construction methods and materials are the same as those used in modern home building, making your garden room more like a detached extension of your home than a traditional outbuilding.


At Green Retreats we have a transparent pricing policy, as well as always displaying an inclusive price. We want to make the process as easy and possible for customers, which is why you can find the prices for every building design and size clearly listed on our website and in our brochure.

What’s more, every listed price includes as many of the ‘essentials’ as we possibly can. You also have the option to swap, downgrade or upgrade any of your options too, creating a building that suits your needs and style. 

Simply start by choosing your design and size.

Our garden rooms start at £11,732 for our cost-effective Basebox building design.
