HUP Extension Cardiff

A Stunning Conservatory Transformation

At Heath Windows and Doors, we’ve helped many Cardiff homeowners turn cold, unused conservatories into beautiful extensions that feel like a natural part of the home. This recent HUP extension in Cardiff is a perfect example of what’s possible when you combine modern materials with thoughtful design.

From Conservatory to Comfortable Living Space

The solution was an Ultraframe HUP extension, designed to deliver the strength, warmth, and longevity of a traditional build while retaining the light, open feel of a conservatory.

The homeowners loved the idea of a garden room but had stopped using their old conservatory because it was simply too cold in winter and too hot in summer. They wanted a bright, relaxing space that would feel like part of their home — not an afterthought — and could be enjoyed every day of the year.

Our solution was an Ultraframe HUP extension, designed to deliver all the comfort and energy efficiency of a traditional build while retaining the light and openness of a conservatory.

We built on the existing base, replacing the old glass structure with a solid, highly insulated HUP system finished with smooth rendered walls that perfectly complement the existing house. The new tiled roof provides exceptional thermal performance, while the carefully placed large glazed panels ensure that light still floods through the space and into the adjoining room.

To make the most of the garden views, we included multiple windows across the side and rear elevations, creating a sense of connection with the outdoors. The rear elevation features a three-leaf aluminium bifold door, which opens fully to extend the living area straight onto the patio — perfect for summer evenings or entertaining friends.

The result is a bright, contemporary extension that feels fully integrated with the home and garden — warm, comfortable, and welcoming in every season.

We removed the old structure and built on the existing base using the HUP system. The new room features a solid tiled roof for insulation and all-season comfort, along with large glazed panels that allow plenty of natural light to flow through. The result is a bright, relaxing space that can be enjoyed throughout the year and still keeps the adjoining room light and airy.

Why Choose a HUP Extension?

The Ultraframe HUP system represents a new era in home extensions. It’s quick to build, highly energy efficient, and offers outstanding design flexibility – making it a smart investment for modern living.

Warm and Energy Efficient

The HUP system is built with advanced insulation in both walls and roof. This keeps the room warm in winter, cool in summer, and reduces heating bills – matching the performance of a full extension.

Design options allow you to choose exactly how much light you let in.

Faster Installation, Less Disruption

Because the HUP structure is pre-engineered, it can be installed far quicker than a traditional build. Most projects take just a few days, minimising disruption and allowing homeowners to enjoy their new space sooner.

Strong, Lightweight Construction

The precision-engineered framework is robust yet lightweight, designed to last for decades while sitting comfortably on most existing conservatory bases.

Flexible Design Options

Choose from tiled or glazed roofs, solid or partially glazed walls, and modern finishes to complement your home’s architecture. Every HUP extension is designed around how you want to live.

Building Regulation Approved

Unlike some conservatory refurbishments, a HUP extension meets full Building Regulations, giving homeowners total peace of mind and adding genuine value to the property.
