If you’re specifying an upcoming development or high quality interior project, you may already be considering pre hung door sets as part of your design and build strategy. Pre hung internal door and frame sets are increasingly popular where consistency of finish, installation efficiency, and long term performance are priorities.
At Apollo DoorSets, we supply high quality European pre hung door set kits sourced from leading German manufacturers. These are not off the shelf doors. They are made to measure, engineered as complete systems, and designed to fit your requirements and deliver a reliable, repeatable result on site.
What is Included in a Door Set?
A door set kit is a complete pre hung door system supplied as a single, coordinated unit. Unlike traditional doors, which are assembled on site from separate components, a door set is manufactured, tested, and prepared as a complete product by one manufacturer.
A typical door set includes:-
- Door leaf
- Frame
- Hinges
- Seals
- Glazing (if specified)
- Door furniture
- Closing mechanisms
- Fully applied finish
Because the system is engineered as a whole, tolerances, alignment, and performance requirements are put in place during manufacture rather than left to . This is one of the key reasons pre hung door sets are increasingly specified on higher value projects.
Door sets can also be manufactured to meet specific project requirements including acoustic performance, fire compliance, glazing configurations, and aesthetic detailing.

Are Pre Hung Doors & Door Sets the Same?
The terms pre hung door, door set, and pre hung door set kit are often used interchangeably, but the principle should remain the same.
A true pre hung door system should:
- Arrive with the door already fitted into its frame.
- Have all machining completed prior to delivery.
- Be finished before it reaches site.
- Function as a complete engineered unit.
The difference with a properly manufactured European door set is the level of precision involved. These systems are produced to exacting German quality standards, with careful attention to detail and repeatable accuracy across large projects. Customers with experience of co-ordinating multiple trades on site will be aware of the issues that can be caused when specifications are “lost in translation”. This can be particularly problematic when the specs were put in place to meet regulatory requirements such as those for fire doors. Using a door set streamlines the install process and means an error free door install experience.
This approach also allows pre hung internal door and frame sets to be installed later in the construction programme, reducing the risk of damage and supporting cleaner handovers.
Door Sets Vs Traditional Doors
With traditional doors, frames are formed on site, doors are hung manually, ironmongery is installed separately, and finishing is often completed by decorators. This introduces variability and depends heavily on site skill.
A pre hung door set removes much of this uncertainty.
Because the door and frame are supplied as a matched pair, with all components already integrated, installation becomes a fitting process rather than a construction task. The result is:
- More consistent gaps.
- Better alignment.
- Fewer defects.
- Reduced snagging.
- Higher overall finish
For developers, contractors, and specifiers, this is not just about convenience. It is about risk management and quality control.
Made To Measure As Standard
One of the defining features of European pre hung door sets is that they are manufactured to your requirements.
At Apollo DoorSets, door sets are made to measure to your bespoke specifications. This allows:
- Frames to adjust to wall thickness.
- Frame spans from 8cm to 50cm.
- Consistent detailing across varying openings.
- Freedom from standard stock sizes.
- Better proportions in both commercial and residential projects.
This flexibility is particularly valuable on refurbishments, mixed use schemes, and design led interiors where standard door sizes often compromise the intended outcome.
Installation Advantages Of Pre Hung Door Sets
Pre hung door set kits are designed around a simplified, single fix installation process. But what does that mean on site?
Because the door sets arrive fully finished and pre assembled:-
- No nails or screws are required.
- No painter is required after installation.
- No maintenance is required post install.
- Doors can be installed later in the programme.
- Risk of damage during construction is reduced.
- Labour on site is significantly simplified.
This makes pre hung internal door and frame sets especially attractive for projects where time, coordination, and finish quality are critical.
Apollo also provides expert support during the installation process, ensuring that on site teams understand the correct fitting approach and achieve the intended outcome.
Design And Finish Options
Bespoke pre hung door sets are not a restrictive system. They are highly adaptable and offer a wide range of choices in regards to finish.
Apollo supplies European door sets in:
- Laminates
- Veneers
- Lacquers
- Contemporary minimalist styles
- More traditional internal door designs
- Glazed and solid configurations
- Sliding and hinged systems
Because the doors and frames are designed as matching components, aesthetic consistency is maintained across the entire scheme.
Why Door Sets Appeal To Specification Led Projects
Pre hung door sets are increasingly chosen not because they are fashionable, but because they solve real problems.
They appeal to:-
- Developers who want predictable outcomes.
- Architects who need design intent preserved.
- Contractors who want fewer defects and faster installs.
- Clients who expect high end finishes.
- Projects where European quality is a priority.
- Schemes where bespoke sizing is unavoidable.
Choosing pre hung internal door and frame sets is less about upgrading and more about applying the same logic used elsewhere in modern construction: control as much as possible off site, reduce risk on site, and deliver a better finished result.
Pre Hung Door Sets for Better Quality Builds
Pre hung door set kits are no longer a niche commercial solution. They are increasingly becoming the preferred option for projects where quality, precision, and consistency matter.
If you are already specifying high quality materials and systems throughout a project, pre hung door sets are simply the natural continuation of that approach: engineered products, made to measure, delivered ready to perform.
