A Sunroom Extension Designed Around the Way You Live

A sunroom extension is an excellent option for homeowners who want to increase their living space without compromising the character of their property. Unlike a traditional conservatory, a sunroom is built as a permanent extension with spray foam insulation for walls and roofing, creating a comfortable room that can be enjoyed throughout the seasons.

Whether you’re looking for more room to entertain, a brighter family living area or a peaceful place to work from home, every project begins with understanding how you want to use the space. Our team works closely with you to design a sunroom that blends naturally with your existing home while meeting your practical needs.

As part of our design-and-build approach, we also provide planning permission guidance where required, helping make the process straightforward from the outset.

More Than Extra Space

A well-designed sunroom extension offers more than additional square metres. It creates a space that improves how you enjoy your home every day.

Bright, Comfortable Living

Large glazed areas allow natural light to flow through your home while insulated construction helps create a comfortable environment throughout the year.

Flexible Space for Changing Needs

Your new extension can become a family room, dining area, home office, reading room or another living space that adapts as your lifestyle changes.

A Seamless Extension of Your Home

Every sunroom is designed to complement your property’s existing architecture, creating an extension that feels like it has always been part of the house rather than an afterthought.

Long-Term Investment

Adding practical, well-designed living space can improve your home’s functionality today while enhancing its appeal for the future.

What’s Included in Our Sunroom Extension Services

Every project is tailored to your property and requirements, but your sunroom extension can include:

• Initial consultation and site survey
• Bespoke extension design
• Planning permission guidance where required
• Complete project management
• Structural construction
• Insulated walls and roof construction
• Windows and glazing installation
• Electrical, lighting and heating installation where required
• Internal finishes
• Final project completion

The final scope of work depends on your property’s existing layout, the size of the extension and your chosen finishes. During your consultation, we’ll explain exactly what’s included in your quotation so you know what to expect before work begins.

Why Choose OS Holding

Choosing the right contractor is about more than the finished extension. It’s about knowing your project will be managed professionally from the first conversation to the final handover.

At OS Holding, we focus on making the process as straightforward as possible by providing one experienced team to coordinate every stage of your sunroom extension.

Turnkey Design-and-Build Service

From the initial site survey through design, planning guidance and construction, we manage the entire project under one roof, reducing the need to coordinate multiple contractors.

Dedicated Project Management

Every renovation is assigned a dedicated project manager who keeps you informed throughout the build and acts as your main point of contact.

Guidance Through Planning

Where planning permission is required, we’ll help you understand the process and provide guidance to support your application.

Fully Insured and Industry Recognised

As a fully insured building contractor and member of the Construction Industry Register Ireland, Construction Industry Federation and National Guild of Master Craftsmen, we are committed to professional standards across every project.

Our Process

Building a sunroom extension should feel organised and transparent from the beginning. Our process is designed to help you understand each stage before work begins.

1. Initial Consultation

We arrange a free, no-obligation site survey to discuss your ideas, assess your property and understand how you’d like to use your new space.

2. Design and Planning

Once we understand your requirements, we prepare a tailored design and provide planning permission guidance where needed.

3. Construction

Our experienced building team carries out the construction while your dedicated project manager oversees coordination and keeps you updated throughout the project.

4. Finishing and Completion

After construction is complete, we carry out the finishing works and final checks before handing over your completed sunroom extension.
