Designline can typically be assembled in just 3–4 days, from £9,550 with free delivery included.

A luxurious veranda with an opening roof

The Designline from Roma Verandas solves the problem every glass roof eventually creates. Its optional sliding roof function opens to release trapped heat and draw a breeze through the space, so the area under the veranda stays comfortable on the days you most want to be outside. Support comes from above, keeping the underside clean.

The construction is exceptionally strong, rated for high wind and snow loads, and the variable 5 to 12 degree pitch allows a precise match to your home.

6m max span on 2 posts

Sloping roof, variable roof pitch 5-12°, with sliding roof function

Luxury With A Purpose
The Designline is a functional design object, not just a good-looking one. The sliding roof prevents heat build-up on hot days while the overhead support structure leaves the space below uncluttered and visually calm.

Strength You Do Not See
Behind the elegant lines is a structure engineered for the highest wind and snow loads, so a south-facing sun trap or an exposed coastal garden is no obstacle. The design and fixing options can be tailored to the space.

Frequently Asked Questions

That is the problem it was designed to solve. The optional sliding roof function opens to let trapped heat escape and draw a breeze through the space, rather than sealing it in under glass. It is the single most useful feature for a south or west-facing garden.

It is an option rather than standard, so you can specify the Designline with or without it. Most customers who are choosing this model over the <a href="https://romaverandas.com/products/topline">Topline</a> or <a href="https://romaverandas.com/products/ultraline-classic">Ultraline</a> are doing so for the sliding roof, so it is worth pricing in from the outset.

The structure carries the roof from over the top rather than from beams beneath it. The practical result is a much cleaner underside when you look up from your seating area, with no supporting framework interrupting the view of the sky.

The Designline has an extremely strong construction rated for the highest wind and snow loads in the range, so exposed and coastal sites are well within its capability. We still calculate loading for your specific address before confirming the span.

The pitch is variable between 5 and 12 degrees, so it can be aligned to your roofline, eaves or door heights rather than forced to a fixed angle. Getting this right is part of the survey, and it makes a significant difference to how settled the finished veranda looks.
