Garden Lodges

Garden Lodges from The Green Room are a smart way to create a living space in your garden.

We design every Garden Lodge with comfort and practicality in mind, creating a fully self-contained home that meets high construction standards. In addition, our one, two and three-bedroom lodges provide an ideal solution for elderly parents, young adults or guests who need their own independent living space.

We design our Garden Lodges to meet the statutory definition of a caravan, including the relevant Caravan Act size and mobility requirements. Where the proposed siting and use comply with the requirements within the curtilage of the main house, you may not need full planning permission. However, we recommend obtaining a Certificate of Lawfulness from the local planning authority before installation, and we can manage the application on your behalf.

We manage every lodge as a complete, turnkey project, with the agreed costs clearly set out in your fixed-price quotation. From foundations and utility connections to the kitchen, bathroom, heating, electrics, flooring and internal fit-out, we take care of the entire installation. We finish the walls and ceilings with smooth plaster, ready for decoration once the new plaster has fully dried.

Need More Space or a Custom Layout?

If you’re looking for additional layout options or a fully bespoke design, a Granny Annexe may be a better fit. Our annexes are designed to offer more flexibility and can be tailored around your exact needs, with full planning support included.

Smart, Self-Contained Living

Garden Lodges are designed to provide both comfort and privacy. In addition, we offer one, two, and three-bedroom layouts, each complete with a shower room, kitchen, and living area.

Garden Lodges and the Caravan Act

We design our Garden Lodges to meet the relevant Caravan Act size, construction and mobility requirements. Where the proposed siting and use are also lawful and remain ancillary to the main house, full planning permission may not be required. In these circumstances, we recommend obtaining a Lawful Development Certificate, which we can manage on your behalf.

Garden Lodge Features and Options

Every Garden Lodge is designed to feel like home, with practical features and quality finishes included as standard. You can also choose from a range of optional extras to suit how you plan to use the space.

Compact Kitchen

Each lodge includes a smart, space-saving kitchen complete with a sink, dual hob, extractor fan, and fridge with freezer compartment. As a result, the layout makes efficient use of space without compromising on practicality or everyday functionality.

 

Hideaway Kitchen Option

For a cleaner, more open feel, you can choose a hideaway kitchen that folds neatly away when not in use. As a result, you can keep the living area flexible, spacious, and uncluttered.

Stylish Standard Kitchens

We offer a range of compact kitchen styles, all featuring high-quality finishes, integrated appliances, and efficient storage solutions. As a result, each kitchen combines practicality with a clean, modern look.

En-Suite Shower Room

All lodges include a fully fitted shower room complete with a walk-in shower, toilet, and sink. In addition, we design each space to be safe, practical, and easy to use every day.

Built-in Wardrobes

We Offer Many Designs and Options

Each bedroom includes a sliding-door wardrobe complete with shelving and drawers. As a result, you can make the most of the available space while keeping the room organised and clutter-free.

Compact Vanity Units

To make better use of the available space, we combine the toilet and sink into one compact unit within the shower room. In addition, you can choose from a range of finishes to suit your preferred style.

Modern Electric Showers

Safety First

Our en-suites feature chrome electric showers with thermostatic controls and a built-in safety stop, providing safe, reliable and comfortable showering for everyday use.

Designed with accessibility in mind, the showers are also suitable for people with limited sight, hearing or dexterity and have received the RNIB Approved Gold Award, providing additional peace of mind.

Efficient Heating

All lodges include Ecostrad iQ Ceramic radiators with Wi-Fi and motion sensing. As a result, you can manage the heating easily while helping to keep running costs low.

Durable Flooring

We offer a range of hard-wearing laminate flooring options that are water-resistant, easy to clean, and designed for everyday living.

Home-Style Interior Finish

Our garden lodges are finished with smooth plastered walls and ceilings, giving the interior the look and feel of a traditional home rather than a caravan-style finish. The result is a warm, comfortable living space that feels familiar, solid and built for everyday living.

Lighting and Safety

We install LED downlights throughout the lodge to create a bright, energy-efficient living space. In addition, we include external lights with PIR sensors near the entrance for added security and visibility.

 

Optional Canopies

Some lodge designs include flyover roofs to provide shelter at the entrance or along one side of the lodge. As a result, they offer added protection and practicality for comfortable all-weather use.

 

Sliding Doors

All wardrobes include sliding doors, which we can also use internally if needed. As a result, they help save space and provide easy access in more compact layouts.

Pitched Roof Option

Choose our dual pitched roof with TapcoSlate tiles to create a vaulted ceiling and add extra space inside. As a result, the lodge feels brighter, more open, and full of character.

 

Comfortable Ceiling Height

We provide a 2.3m ceiling height as standard to create a taller, brighter, and more comfortable living space.

What’s the Difference Between a Garden Lodge and a Granny Annexe?

Garden Lodges and Granny Annexes are very similar. Both provide self-contained living space in the garden, complete with a kitchen, bathroom, bedroom and living area. However, the main difference is their design flexibility and the planning route they may follow.

A Granny Annexe is designed around the customer’s individual requirements. Depending on its dimensions, construction, siting and intended use, it may follow the Caravan Act and Lawful Development route or require full planning permission.

By comparison, our Garden Lodges follow established layouts and are manufactured in two sections to meet the relevant Caravan Act size, construction and mobility requirements. Where the proposed siting and use are also lawful and ancillary to the main house, full planning permission may not be required. However, we recommend obtaining a Lawful Development Certificate before installation, and we can manage the application on your behalf.

Therefore, if you need more space or a fully bespoke layout, a Granny Annexe may be the better option.

Garden Lodge Construction

SIPs Panel Construction

We manufacture every Garden Lodge using structural insulated panels (SIPs) for the main structure. As a result, each lodge benefits from excellent strength, reliability, and a faster, more efficient build process.

In addition, we manufacture the lodges in two sections before transporting them to your property and assembling them on site.

Insulated and Energy Efficient

SIPs provide excellent thermal performance, helping to maintain a comfortable indoor temperature throughout the year. As a result, they reduce heating demands and can help lower your energy bills.

Durable External Finishes

We use a combination of fibre cement and PVC wood-effect cladding to create a smart, low-maintenance finish. In addition, we manufacture the roof trims, fascias, and soffits from durable PVC, aluminium, or steel to provide long-lasting protection in all weather conditions.

Quality Windows and Doors

Every lodge includes secure PVCu windows and doors fitted with 28mm argon-filled sealed units. As a result, they meet high energy-efficiency standards while helping to keep your lodge warm, quiet, and secure throughout the year.

Low-Maintenance Roof System

Flat or Pitched Roof Options

We finish our flat-roof models with a seamless EPDM membrane to provide long-term weather protection. In addition, we use Tapco slate tiles as standard on all pitched-roof models for a durable and attractive finish.

Lodge Siting

We support all of our garden lodges above the ground using screw piles. As a result, air can flow beneath the structure while also allowing space for lifting cradles or straps if the lodge ever needs to be moved in the future. In addition, the screw piles can be removed with minimal ground disruption if required.

Garden Lodge FAQs

What is a garden lodge?

A garden lodge is a self-contained living space installed within the grounds of a main home. It can include a bedroom, living area, fully fitted kitchen and bathroom, providing comfortable accommodation for a family member or guest.

Our garden lodges are designed to meet the relevant Caravan Act requirements and can provide a practical solution for long-term, year-round living while remaining connected with the main home.

What’s the difference between a garden lodge and a granny annexe?

Both provide self-contained living accommodation, but the main difference is the design and planning route.

Our garden lodges are designed to meet the relevant Caravan Act size and mobility requirements. Where the proposed siting and use are also lawful, full planning permission may not be required. In these circumstances, we recommend obtaining a Lawful Development Certificate (LDC) before installation.

Our granny annexes offer greater design flexibility. They can also meet the relevant Caravan Act requirements where appropriate, or proceed through full planning where the design, dimensions or individual circumstances require it.

We’ll assess your property and requirements and advise on the most appropriate option and planning route for your project.

How much does a garden lodge cost?

Our one-bedroom garden lodges start from £85,000, including foundations, agreed utility connections, installation, a fully fitted kitchen and bathroom, heating, electrics and flooring.

Larger garden lodges and bespoke designs will cost more depending on the size, layout, specification and site requirements. Following your free site survey, we’ll provide a clear, fixed-price quotation based on your chosen design.

Are your garden lodges classed as mobile homes?

Yes. Our garden lodges are designed to meet the legal definition of a mobile home under the Caravan Act, including the relevant size and mobility requirements.

This does not mean the lodge has wheels or is designed to be moved regularly. Instead, it must be capable of being moved as required by the legislation. In practice, our garden lodges are installed as long-term living accommodation within the grounds of the main home.

Is planning permission required for a garden lodge?

Our garden lodges are designed to meet the relevant Caravan Act size and mobility requirements. Where the proposed siting and use are also lawful, full planning permission may not be required.

We recommend obtaining a Lawful Development Certificate (LDC) before installation to formally confirm the lawful use of the lodge. We can prepare and manage the application with the local authority on your behalf.

What is a Lawful Development Certificate?

A Lawful Development Certificate (LDC) is a legal document issued by your local planning authority confirming that a proposed development or use is lawful.

It is not the same as planning permission. Instead, it provides formal confirmation that the proposed use or development is lawful without requiring a full planning application.

Where an LDC is the appropriate route for your granny annexe, we can prepare and manage the application on your behalf and deal with the local authority throughout the process.

For further information, visit the Planning Portal guidance on Lawful Development Certificates.

 

Do garden lodges come with kitchens and bathrooms?

Yes. Our garden lodges include a fully fitted kitchen and bathroom as standard, along with heating, electrics, flooring and the other essential features needed for comfortable, day-to-day living.

You can also choose from a range of kitchen, bathroom and internal finishes to tailor your lodge to your requirements.

Are garden lodges insulated for all-year use?

Yes. Our garden lodges are built using Structural Insulated Panels (SIPs), which provide high levels of insulation and energy efficiency.

The highly insulated construction helps retain heat during colder weather and reduces heat transfer during warmer weather, creating a comfortable living space for year-round use.

Do you install garden lodges in Northamptonshire?

Yes. We’re based in Corby, Northamptonshire, and design and install bespoke garden lodges throughout Northamptonshire and the surrounding areas.

We provide a complete service, from your free site survey and bespoke design through to planning, groundworks, utility connections, installation and final handover.

What does the price of a garden lodge include?

Our garden lodge price includes the essential elements of your project, including the agreed planning or certification work, foundations, SIPs construction, utility connections, electrics, heating, flooring, a fully fitted kitchen and bathroom, internal plastering and installation.

Following your site survey, we’ll provide a clear, fixed-price quotation based on your chosen design and specification, so you know exactly what is included before your project begins.

Optional features and upgrades, such as built-in wardrobes, will be clearly included in your quotation if selected.

Are garden lodges suitable for long-term living?

Yes. Our garden lodges are designed for comfortable, year-round living, with high levels of insulation, heating, a fully fitted kitchen and bathroom, and everything needed for everyday use.

They can provide long-term accommodation for elderly relatives, adult children or other family members while allowing them to live close to the main house.
