Refurbish or fully convert?
A roof-only upgrade retains more of the conservatory. A full hup! conversion replaces wall sections and roof to create a different type of space.
Windows, doors & extensions across Essex · Brightlingsea showroom
Turn an underused conservatory into a more comfortable space. We assess what can stay, then design a hup! transformation around the way you want to live.
Family-run. Locally built. Designed around you.

MAKE SPACE FOR WHAT MATTERS
Start with the way you want to use your room. We will help you bring the right materials, light and layout together.
WHY BUILD WITH hup!
Insulated wall panels help create a comfortable room. Ultraframe quotes a wall U-value of 0.17 W/m²K for its specified hup! wall build-up.
Precision-made panels arrive ready for assembly, reducing on-site cutting and waste. Your full programme includes foundations, roof and finishing work.
Choose your wall finish, roof, windows and doors to suit your home. Create a contemporary addition or a more traditional look.
Build a new extension or transform an existing conservatory. Suitable existing bases may be reused after a survey and structural assessment.
Performance depends on the complete specification. Ultraframe hup! wall specifications ↗

LET'S MAKE IT SIMPLE
Tell us what you would love to change. Our local team will discuss the design, assess your property and prepare a quotation around the work your project needs.
Visit our Brightlingsea High Street showroom to talk through materials, glazing and roof options in person.
Explore our showroom ↗Sometimes. We assess the base, foundations and proposed loads before confirming whether reuse is suitable. A conversion may require strengthening or new foundations.
hup! walls can be paired with Ultraframe glass, tiled, hybrid solid/glass and flat roof systems. The right choice depends on the layout, daylight and character you want.
The panel system can make the structural build faster than conventional methods, but the full programme depends on groundwork, access, roof specification and internal finishing. We discuss a project-specific schedule with your quotation.
Requirements depend on your home, location and the proposed work. We discuss the approvals and structural checks your project needs before work starts.
Ask Spectrum about finance options for your project. Eligibility, deposit, rates and terms will be confirmed with your quotation. View finance information ↗
