Find Your Perfect Sunroom Extension with Ultraframe

Our conservatories, orangeries and house extensions are sunrooms. Designed to let in light, retain warmth, and create a sense of space, our roof systems will meet the needs of your project.

Sunroom Extensions: Your Choices

Our diverse range of products can be customised to suit your precise requirements. If you’re looking for design inspiration, look no further than Ultraframe.


When designing your sunroom extension, you’ll need to consider three separate spaces: your home, the room you’re creating, and your garden. These different areas will need to flow together logically and feel connected – else your plans may not work.

Choose our Designer Conservatory if you want to create a room with a view. This is a sunroom extension that’s compatible with bi-fold doors, which can be opened to almost threshold length to create extensive panoramas of your garden.

The impact of using bi-fold doors to open up the space is clear in the image below, which reveals how light enters from all angles to create a roomy environment.

Your modern conservatory will feature a Classic roof that’s extensively glazed, which means even more light will be able to enter your room. Choose aluminium instead of uPVC to improve external views and a sense of space further.

How to Refine Your Design

Use super-insulated columns to create a contemporary external effect. Large columns will sit at the corners of your installation, and you can continue the sequence user smaller inline versions.

Fluted or flat columns can be deployed to achieve contemporary or traditional effects. Your columns will reward you with thermal retention levels five times greater than a brick pier of the same size.

So that people can navigate easily between your three spaces, use French doors to connect your home to your sunroom extension. These can be closed for privacy when you need some quiet time.

Your Designer Conservatory will include an insulated pelmet that skirts the perimeter of your room and which can include spotlights and speakers, depending on your requirements.

Turn your sunroom extension into a living room by using soft furnishings and carpeting. Choose from our range of RAL colours to create a design scheme that ties in with your arrangement.

This interior shot of our Designer Conservatory shows how the internal pelmet is used to let in lots of light to create a bright room when its darker.


If you want to create an open-plan space that can be used to serve a range of functions, you’ll want to explore our Livinroof House Extension.

Livinroof is both a solid conservatory roof and glass conservatory roof. You can place glazing of any shape anywhere within its structure.

Internally, an insulated pelmet retains warmth and can include spotlights to keep your room cosy at night. Speakers can be added to it, too.

The above features – when combined – are instrumental in creating a light-filled space that’s perfect for entertaining or relaxing in year-round.

As you can see below, the Livinroof uses light to great effect to create an open-plan kitchen that contrasts bright and earthy colours to create warmth.

Create your dream kitchen diner extension by:

  • Excluding internal doors from your design, so that your new room is accessible from your kitchen area (our Livinroof House Extension is designed to comply with Building Regulations, which your Ultra installer will be able to help you with).
  • Depending on the space you have available, you could create a dining room that also includes a seating area with couches where guests could relax afterwards. Carpeting could be used to separate the space into two distinct sections.
  • To allow easy passage from your kitchen through to your garden, use bi-fold or sliding patio doors to introduce your sunroom extension to the outside. If space is limited, opt for French doors that open fully outward for better access.

When viewed from the outside, the Livinroof is equally as stunning. As you can see, brick piers can be substituted for super-insulated columns if a more tradtional look is preferred.


Our Contemporary Orangery uses the Ultrasky roof to enable builds of different scale. Create a sunroom extension up to 6.5m in width when you include our structural goal post in your design plans. Building a wide-spanning structure is achievable with this roof lantern system.

Internally, an insulated pelmet will keep your room space warm. Because it can include lighting and speakers, you’ll be able to listen to music when entertaining or relaxing. Add a central lighting panel if you want to create a focal point in your extension and include additional lighting.

Externally, you’ll be able to hide your guttering using our decorative cornice. Three flat designs are available that are installed at 90 angles and work with constructions of all sizes. A curved cornice can be used for any size, shape or style of orangery – so you won’t need to compromise.

A flat cornice is used to hide the guttering in the image below and super-insulated columns sit at the corners to frame the bi-fold doors.

Turning the narrow section into a dining room that’s separated from the squarer section by French doors, so that it still feels like a separate area but works as a continuation of your design.

Connect your orangery to your home via French doors, so that your space can be screened off when privacy is needed but opened up when your house is busy.

Use the larger part of your sunroom extension as a lounge that your family or visitors can relax in when you’ve finished eating.

Externally, use masonry to create a traditional effect or flat super-insulated columns to communicate a modern look.

Open your T-shaped orangery to the garden with bi-fold doors, so that guests can come and go freely during busier times.

Here, the Ultrasky Roof is used to create two distinct spaces - a large lounge area that leads into an alcoved dining room.

Sunroom Extensions: FAQS

How big can a sunroom extension be?

Your sunroom extension, conservatory or orangery can’t take up any more than 50% of the land around your home as it stood when it was first built. Take care to account for sheds, greenhouses and any other outbuildings, which will need to be included in your calculations.

Can I choose different colours for my sunroom extension?

You can customise your sunroom extension using a range of RAL colours. The completed installation will blend in with the rest of your home and look the way you expected.
