Non-standard openings
Review project dimensions and combinations within the available ranges of the selected window or door system.
Made to measure for UK project briefs
Bespoke Aluminium Windows and Doors for the UK
Develop a project-specific window and door package around your drawings, opening sizes, preferred configurations, colours, glazing and hardware. DERCHI supports residential briefs, trade enquiries and development schedules from review through manufacturing and supply coordination.
Made-to-measure configurations
Custom colours and finishes
Project-specific glazing options
Trade and supply-only briefs
Start with the building
Bespoke windows and doors should resolve the project brief—not force it into a standard size
A useful quotation starts with the opening schedule, architectural intent and installation context. The selected system can then be reviewed against the required operation, glass, finish, hardware and documentation.
Architectural coordination
Align opening style, frame appearance, colour, glazing and hardware with the elevation and room use.
Repeatable project schedules
For developments, organise types around the schedule, quantities, handing and agreed packaging needs.
Configuration-specific evidence
Confirm the technical information and test documentation that applies to the exact system under review.
Who we support
A clearer route for builders, developers, architects and residential clients
Different teams need different information. Start the enquiry with the documents and decisions relevant to your role.
Builders and contractors
Send the window schedule, opening information, quantities and required delivery stage for take-off and scope discussion.
Residential developers
Identify repeated unit types, phase quantities, approval needs and packaging priorities for a development review.
Architects and specifiers
Review system direction, glazing, finish, hardware, drawings and available performance documentation early.
Bespoke home projects
Bring plans, approximate opening sizes and visual preferences so suitable product directions can be narrowed down.
What can be configured
Define the bespoke details that affect fit, appearance and operation
Options vary by product series. Use this checklist to prepare the brief, then confirm compatibility before specification or purchase.
Product directions
Bespoke window and door solutions for residential and development projects
Select the product family first, then confirm which size range, operation, glazing and finish options are available for the chosen system.
Custom aluminium windows
Review casement, fixed, sliding and tilt-and-turn directions according to ventilation, view and opening requirements.
Review custom window options
Sliding and folding doors
Compare multi-panel door directions for patios, garden connections and large openings, subject to system limits.
Compare aluminium door categories
Entrance and hinged doors
Coordinate door style, panel arrangement, sidelights, finish and hardware around the intended entrance design.

Made-to-measure directions for different residential project types
Use the building type and procurement stage to frame the enquiry. Product suitability, dimensions and project documentation still need configuration-specific review.
New-build homes
Coordinate types with the elevation, room use, opening schedule and construction programme.
Renovations and extensions
Review existing openings, proposed structural changes and retained elements.
Residential developments
Organise repeatable unit types, plot or phase references, quantities and approvals.
Bespoke private homes
Develop coordinated window, entrance and large-opening directions around the brief.
From drawings to supply
A project workflow built around confirmation
The exact scope, specification and timing are confirmed after the project information and selected configurations have been reviewed.
Share the brief
Provide drawings or schedules, dimensions, quantities, location and intended stage.
Review requirements
Discuss product family, opening types, glass, colours, hardware and documents.
Confirm scope
Align proposed configurations, commercial scope and delivery terms before production.
Manufacture and inspect
Proceed through preparation, cutting, assembly, glazing, inspection and packing.
Coordinate shipment
Confirm packing, trade terms, delivery point and project-team information.
Plan the procurement route
Supply-only and project trade enquiries
Confirm who is responsible for measurement, specification approval, import arrangements, delivery and installation before the order scope is agreed.
Supply-only project brief
For projects working with their own UK installer or contractor, submit the information needed to confirm product and supply scope.
- Drawings or opening schedule
- Approximate sizes and quantities
- Preferred configurations and finishes
- Delivery destination and target stage
Trade or development brief
For builders and developers, structure the review around repeatable types, approval information and procurement sequencing.
- Window and door type schedule
- Unit, plot or phase references
- Required technical documents
- Packaging and shipment needs
Specification note: dimensions, glass build-ups, hardware, performance values and document availability depend on the selected system and configuration. Ask DERCHI to confirm which evidence applies to the exact proposal and whether it is suitable for the intended UK project requirement.
Specification and documentation
Request evidence for the exact configuration—not the product category in general
UK requirements depend on the building, location, opening and selected system. Ask for the documents that apply to the proposed configuration and have the project team assess their suitability before specification.
Include these items in the document request
- Selected system and opening configuration
- Proposed sizes and glazing build-up
- Hardware, finish and threshold requirements
- Target performance or project requirement
- Required drawings, data or test documentation
Important: the presence of a certificate or test report does not establish blanket UK approval for every size, glass build-up or opening type.
Manufacturing visibility
See where the bespoke package is manufactured and checked
DERCHI's official factory information shows an integrated production environment and a sequence from profile preparation and cutting through assembly, glazing, inspection, packaging and shipment.
Project gallery and case fit
Use these application visuals to discuss the intended opening and architectural direction
These are official DERCHI product and architectural context images. They are not presented as UK case studies; use them to identify the scale, operation and visual treatment you want the project team to review.
Project questions
Frequently asked questions about bespoke windows and doors
DERCHI's official product information supports project-based customisation for size, opening type, glazing, colour and hardware. Final dimensions must remain within the limits of the selected system, so drawings and sizes should be reviewed before quotation.
Send architectural drawings or a window schedule where available, approximate sizes, quantities, opening directions, preferred colours and glazing, the UK project location and the target project stage.
DERCHI lists multiple finish and glass directions. Availability depends on the chosen series, dimensions and brief, so the exact finish and glazing build-up should be confirmed in the proposal.
A supply-only brief can be discussed for projects using their own installation team. The quotation should confirm measurement and approval responsibilities, trade terms, delivery point, documentation and any installation guidance included.
Availability is product- and configuration-specific. Share the intended UK requirement and request the exact drawings, data and test or certification documents that apply. A document should not be treated as blanket approval for every configuration.
DERCHI publishes dedicated support routes for builders, contractors, architects and commercial teams. Identify your role and provide the project information, drawings, quantities and documentation needs relevant to that stage.
