Introduction
When replacing an existing door or planning a new one, flexibility in size is crucial. That’s where aluminium composite doors shine. Whether you’re upgrading a period property or building a contemporary home, a custom-built aluminium composite door ensures a perfect fit, optimal performance, and standout kerb appeal. In this article, we’ll explain how the made-to-measure process works, what’s included, and why it makes all the difference.
Quick Answer: Yes, They Are 100% Made to Measure
Unlike off-the-shelf doors from national hardware chains, Aluminium Composite Doors from GFD Homes are custom-built to your exact requirements. Whether your property is new-build, period, or something in between, you won’t need to compromise on size, style, or finish.
This applies to:
- Smart Signature Doors
- Smart Designer Doors
- All side panels, top lights, and thresholds
Every order is manufactured based on your measurements, not standard sizes.
Why Made to Measure Matters
1. Perfect Fit, Better Performance
A door that’s too tight or too loose can lead to:
- Draughts
- Water ingress
- Difficulty opening/closing
- Lost thermal efficiency
A made-to-measure Smart door avoids all of this with:
✅ Precision CNC manufacturing
✅ Factory-assembled frames
✅ Tight tolerances around the sash and threshold
This ensures an exact fit, even in older properties where frames might not be square.
2. Complete Design Flexibility
Made to measure means you can:
- Select custom widths and heights
- Configure side panels or top lights
- Specify open-in or open-out direction
- Choose threshold height (standard, low, or flush)
- Set handle heights for accessibility or personal preference
This level of control means the door works for your layout—not the other way around.
3. Compliance with Building Regulations
Building regs like Part M (accessibility) and Part L (energy efficiency) often require specific sizes and thresholds. A made-to-measure Smart door:
- Can meet Part M with low or flush thresholds
- Achieves U-values under 1.2 W/m²K for Part L
- Ensures correct step heights and frame clearances for new builds
Standard-size doors often fall short of these requirements—especially in extensions and modern self-builds.
How the Process Works at Aluminium Composite Doors at GFD Homes
Ordering a made-to-measure aluminium composite door is easier than you might think:
Step 1: Choose Your Door Style
Browse Smart Signature and Smart Designer models at Aluminium Composite Doors, and select your preferred design.
Step 2: Configure Your Size & Options
Using our online configurator, set:
- Width & height
- Side panels or glazing
- Colours (RAL or dual colour)
- Threshold type
- Locking system and handles
Step 3: Confirm Your Measurements
We offer help with measuring if you’re DIY-ing, or send a surveyor if you’re booking supply and fit.
Step 4: Custom Fabrication
Your door is made from scratch by Smart Systems in the UK—cut, assembled, and finished to your exact specifications.
Step 5: Delivery or Installation
Once ready (usually in 4–6 weeks), your custom door is delivered with all components ready for fitting—or installed by GFD’s team.

Can I Replace a Standard Door with a Custom One?
Absolutely. Whether your opening is:
- Wider than average
- Taller than average
- Slightly uneven
- Needs to accommodate side or top glazing
…a made-to-measure Smart door can be built to suit. It’s often easier than trying to modify your brickwork to fit a standard door.
Ideal for Period Properties and Renovations
Older homes often have non-standard door sizes. A Smart Signature or Designer door is perfect if you want:
- A clean, modern upgrade
- To preserve a heritage look with woodgrain or traditional styling
- Better thermal and sound insulation without rebuilding the frame
Plus, dual colour options let you match traditional interiors with modern exteriors.
Can I Include Extras in a Made-to-Measure Door?
Yes—and they’re integrated during manufacture. You can add:
- Security upgrades (slam lock, digital lock, security cylinders)
- Bar or pull handles
- Spyholes or viewers
- Decorative or privacy glazing
- Tinted or laminated glass
- Side or top panels
Everything is precision-cut and assembled together, not retrofitted later.
