Aluminium Windows, Doors & Sliding Doors for Gerrards Cross Redevelopments
Trusted by architects, self-builders and developers delivering replacement dwellings and high-spec new builds across Gerrards Cross and Fulmer. Precision-engineered aluminium systems for large detached homes where the brief is architect-led, not off-the-shelf.
Built for Gerrards Cross-Scale Projects
Gerrards Cross has a different profile to the rest of our coverage area. The demand here isn’t a single replacement window — it’s replacement dwellings, self-builds, and multi-unit redevelopments on large plots, specified by architects and delivered to a standard that matches the site value. We supply and install the aluminium systems that these projects are actually designed around.
Replacement Dwellings
Full-plot rebuilds where the glazing package is specified from the architect’s drawings, not retrofitted to an existing opening.
Self-Builds
Bespoke detached homes where the owner and architect are making every material decision, including frame depth, sightlines and finish.
Multi-Unit Redevelopment
Small-scale developments — such as the type of six-unit scheme currently coming forward on Fulmer Drive — needing consistent, specifiable systems across every plot.

Specified to Meet the Future Homes Standard
Large detached self-builds and replacement dwellings in Gerrards Cross are exactly the projects where the tightening U-value regulations bite hardest. We specify systems that are ready for it now, not systems that will need revisiting in two years.
1.2 W/m²K as Standard
Meeting the current target with double or triple glazing depending on the system.
0.8 W/m²K Capable
Reynaers systems engineered to reach Passive House-level performance where the brief demands it.
Full Building Control Support
Documentation and U-value certification supplied to satisfy Buckinghamshire building control.
Consistent Specification Across Units
One system, one supplier, one installation standard across multi-plot developments.
Working With Architects and Developers
We’re set up to work from architectural drawings rather than a homeowner brief. That means providing U-value and performance data at RIBA Stage 3-4, sample frames and finishes for client sign-off, and a fixed specification that carries consistently across every plot on a multi-unit scheme.
Whether it’s a single replacement dwelling on a private road or a small consented scheme like the redevelopment coming forward on Fulmer Drive, the requirement is the same: a glazing partner who can work to the drawings, hold the spec across every unit, and deliver on a construction programme.
How We Work on Larger Projects
Drawing Review
We work from architect’s plans and elevations to confirm system, sizes and performance targets before survey.
Specification & Sign-Off
Sample frames, RAL colours and glazing options presented for client and architect approval.
Programme-Led Manufacture
Bespoke manufacture scheduled against your build programme, not ours.
Installation Across the Site
Consistent fitting standard whether it’s one plot or a multi-unit development.
Areas We Cover
Based in Windsor, we regularly work on projects across Gerrards Cross, Fulmer, and the wider Buckinghamshire and Thames Valley area.
Frequently asked questions
Can you work directly from architect’s drawings?
Yes — we regularly quote and specify from RIBA Stage 3-4 drawings, providing U-value and performance data before a physical survey takes place.
Can you hold one specification across a multi-unit development?
Yes. For small-scale redevelopment schemes we can supply and install a single, consistent aluminium specification across every plot, simplifying sign-off and warranty.
Do your systems meet the Future Homes Standard?
Our Reynaers systems are specified to meet the current 1.2 W/m²K target and can be configured toward the 0.8 W/m²K Future Homes Standard target where the project requires it.
Do you offer sample frames for client approval?
Yes, we provide sample frames and finish options for architect and client sign-off before manufacture begins.
