Bespoke steel doors UK: Luxury home installations and case studies

For more than 100 years, discerning and style-conscious homeowners have understood the unique combination of beauty and strength that epitomises the black steel door. For Crittall – the pioneering firm behind this iconic design – this attitude represents a continuation of a legacy built on longevity, technical rigour and a reputation earned through generations of British manufacturing. 

Within luxury homes, the appeal of custom steel doors lies in how they shape space. Slim sightlines and generous glass doors allow natural light to move freely through an interior while maintaining structure and privacy. Crittall’s Innervision internal range captures this balance with clarity. Each steel door is made to measure, giving designers confidence when specifying single leaves, double doors or fixed screens across complex layouts. 

Design flexibility through bespoke engineering

Design flexibility sits at the heart of the system. Privacy glass options such as reeded, satin or patterned finishes soften views for bathrooms, studies and meeting areas while preserving brightness. For safety led projects, Innervision fire doors deliver certified FD30 fire protection without heavy profiles. The result is a refined solution supported by robust construction, hot dip galvanised steel and a Duralife® powder coat that delivers lasting durability. 

Sliding bespoke steel doors extend this versatility further. Pocket, rebate and face mounted configurations allow large glass doors to disappear into the fabric of a building or stand as a deliberate architectural feature. These arrangements suit luxury apartments and compact townhouses where floorspace must be used with care. 

Case study: South West London renovation

A London home shortlisted for the Crittall House of the Year Awards 2025 demonstrates the impact of this approach. Working with Bespoke Glazing Design, ADE Architecture and Sarah Brink Design, a refined renovation in South West London centred on a set of bespoke Crittall pocket doors, a rare feature in residential settings. When closed, they define each room with clean lines. When open, they retreat fully into the walls, creating uninterrupted flow between spaces. 

The homeowner described the effect. “Each time we pass through those doors, there’s a moment of transition that feels purposeful. It’s a reminder of how good design can shape how we live.” In this home, the doors influence how the house is used from room to room, introducing sophistication through movement and proportion rather than ornament. 

Finishes that reward long term living

Finishes contribute strongly to the perception of quality. While black steel doors remain iconic, Crittall offers a wide range of colours in RAL or BS palettes, including matte and satin options that counter the old myths around fingerprints and maintenance. A damp cloth is usually all that is required to keep frames pristine, giving homeowners reassurance alongside visual appeal. 

Externally, Crittall steel entry doors can be specified with thermally enhanced systems such as W20 TE® to improve insulation and limit heat loss while retaining slim profiles. Multipoint locking, laminated glazing and superior strength reinforce the sense that these are quality steel doors designed to deliver longevity. 

In a sector where heritage often gives way to fashion, Crittall’s bespoke steel doors continue to stand the test of time. They are chosen for the craft behind them, the knowledge that supports every specification and the assurance that each installation carries forward a reputation built on precision, durability and confidence.
