FAQ

Everything You Need
to Know—Upfront

Planning a home upgrade can feel overwhelming, but we’re here to make it easy.

We’re here to help! If you need more information about our conservatories, windows, doors, or renovations, get in touch with our team. We’ll be happy to answer your questions and provide expert advice.

Do I need council consent for my conservatory, windows, or renovations?

Some projects, like conservatories and structural renovations, require council consent, while window and door replacements often don’t. We handle all necessary permits, including engineering reports and compliance approvals.

What are the benefits of upgrading to double glazing?

Double glazing improves insulation, reduces noise, and enhances energy efficiency. Our exclusive 40 Series Frame provides superior thermal performance and a sleek, modern look.

Can I customise my conservatory, windows, or doors?

Absolutely! We offer a range of styles, colours, and finishes to match your home’s look and your functional needs. Our team works with you to design the perfect solution.

Do you provide full installation and project management?

Yes! Our in-house team of qualified builders and aluminium specialists handle everything from design and council approvals to installation and final inspections.

What areas do you service?

We primarily serve Canterbury, including Christchurch, Rangiora, Ashburton, and surrounding rural areas. For larger projects like conservatories, we can service the wider South Island.

Testimonials

Customer testimonials

“Fabulous in every way! We got quite a few quotes for new windows/doors and the products & quotes varied greatly. In the end we went with Ultimate Design because they offered a top quality product, they were very professional and presented us with a very appealing quote saving us thousands of $$$$.”
Shelley H.
“Thank you Fordy for your service and communication over the past 2 years. We had all our windows and sliding doors replaced with double glaze. I even got my dream black mirrored front door and smart lock. Hubby is still recovering from the cost of that door! Anyway, I will continue recommending your company!”
Deidre L.
“We were very impressed with the design advice for our new conservatory and found it easy to envisage how it would look. Construction was very quick, surprising our friends who commented "it's in already?" The completed project complements the existing layout and looks as if it was installed as part of the house rather than as an addition.”
Garry H.
"Love my new door. Replaced my rotting wooden door with a dodgy lock with a sleek, super low maintenance aluminium set. It was an easy process from quote to installation. Hannah nailed the colours and the builders were a pleasure to have on site. Highly recommend these guys for similar renovation work."
Lesley Isaac
"Ultimate Design & Renovation Ltd did an amazing job! Hannah was fantastic to deal with—professional, friendly, and always helpful. We absolutely love our new doors; the quality and craftsmanship are outstanding. Highly recommend their services!"
