GallerySteel windows UK: Why premium developers choose them for landmark projects
- 2 February 2026

When embarking on a landmark project, premium developers will be keen to ensure their undertaking is aesthetically stunning, robustly practical, sustainable, and designed to withstand the test of time. Choosing Crittall for landmark projects is a decision usually driven by the need to balance historic integrity with high-performance modern engineering, including advanced locking mechanisms and effective heat transfer management: Crittall having become the gold standard for buildings that require a timeless aesthetic.
In this blog we’ll take a look at why architects and developers select Crittall steel windows UK time and time again for high-profile landmark developments. Whether embarking on a high profile new build or a historically-sensitive renovation, Crittall has steel windows to perfectly fit your landmark project.
Proven Longevity – architecture for generations to come
Landmark projects are designed to last centuries, not decades. Crittall is one of the few manufacturers that can point to “living case studies”—windows installed in the 1920s and 30s that are still in operation today. This is demonstrated by our recent return to Adelaide House in London to replace windows Crittall originally manufactured for the building over 100 years ago. While remaining true to the original aesthetic of the building, the replacement Crittall windows for this building deliver outstanding energy efficiency. Modern Crittall units are hot-dip galvanised and finished with “Duralife” powder coating, effectively eliminating the rust issues that affected pre-war steel windows. Adelaide House’s new windows will hopefully remain in place for another century as testament to the longevity of our products.
Like-for-like replacement
If a venture involves the renovation of a Grade I and II listed building, planning authorities will often mandate “like-for-like” replacements for architectural features such as windows and internal doors. Crittall can replicate the exact slender sightlines, glazing details, and clean lines of original 19th and 20th-century designs to perfection, enhancing their overall aesthetic appeal. As steel is three times stronger than aluminium, Crittall can create the incredibly thin frames synonymous with landmark architecture of Modernist and Art Deco periods, whilst bringing the building bang up to date in terms of energy efficiency. At this beautiful building in historic Bath for example, we were able to replace the existing steel windows with modern windows to hit thermal targets at this World Heritage Site.
Unbeatable structural strength and security
Engineered for the demands of modern architecture, steel offers the ultimate in design versatility with minimal maintenance needs. Its immense strength allows for slimmer profiles and larger open spaces, making it a cornerstone of innovative new building projects. For older buildings, while heritage looks are maintained, modern Crittall systems (like the T60) feature advanced thermal breaks and high-performance double or triple glazing, allowing old landmarks to meet modern performance ‘Net Zero’ building standards while minimising unwanted heat gain and reducing energy bills. The design flexibility of these systems ensures that they can seamlessly integrate into various architectural styles. Additionally, bifold doors can complement these systems by enhancing natural light and accessibility – vital for public and commercial projects.
Sustainability & Circularity
At the heart of Crittall’s sustainability mission is the material itself: steel. Unlike many alternatives, steel is 100% recyclable, capable of being repurposed indefinitely without any loss in structural integrity. By closing the loop on production, we significantly reduce our reliance on virgin resources. Combined with their robust construction, slim profiles, and extraordinary lifespan, which offers low maintenance requirements resistant to corrosion and warping, along with exceptional thermal performance, Crittall products aren’t just built for today—they are engineered to endure for generations, making frequent replacements a thing of the past. One major benefit of our approach is that with today’s landmark projects being heavily scrutinised for their environmental impact, it makes sense to future proof development and refurbishment alike, especially when considering the integration of outdoor spaces.
