Architectural and Custom Windows in Las Vegas
An arch above an entry, an angled window under a roofline or a group of curved and rectangular panes can give a home its defining character. Among the window styles a home can use, architectural windows begin with that geometry. The project needs to preserve or create the right shape, then connect it to a buildable product and an installation that fits the wall.
Agave Windows helps Las Vegas homeowners plan custom-shaped replacement windows with careful attention to proportions, glass and surrounding finishes. A useful proposal makes the shape understandable before it becomes an order.

The short version
Custom-shaped windows such as arches and angled tops are ordered from measured drawings or templates, because width alone does not define a curve. Many shaped units are fixed, so say early if you need one to open.

Begin with the reason the shape matters
Some projects aim to preserve an existing architectural feature. Others introduce a different shape during a remodel. Those are different design tasks. Replacing a familiar arch may require close coordination with existing stucco and nearby windows, while a new geometric opening may need a broader review of structure and exterior appearance.
Tell us which feature must stay: the curve, the overall height, the relationship to a doorway or the alignment with adjacent glass. If you want a change, explain what is not working now. A photo showing the entire elevation often communicates the goal better than a close-up of the glass.
Avoid treating custom as a promise that any imaginable shape can be built in any size. Product families have manufacturing, glass and installation limits. The design needs to be matched to those limits before the order is approved.

Describe the shape with enough information to distinguish it
The word arch leaves the curve unresolved. A half-round is semicircular; a segmental arch has a shallower curved rise for a given span. A triangle or angled-top unit can also have unequal sides. If two outlines share their widest dimension, they still may meet the wall at different heights and angles.
For an illustrative geometry exercise, a 60-inch span with a 30-inch semicircular rise describes a half-round outline. A 60-inch span with a 12-inch curved rise describes a much shallower outline and cannot be ordered as the same half-round. These are conceptual dimensions, not manufacturing measurements or a supplier's available sizes.
The supplier must identify the reference being measured: outside frame, visible glass, rough opening or another required edge. Measuring the old glass alone can omit the frame and its relationship to the wall. A template must likewise be tied to a named reference surface and viewing direction.
| Shape feature | Record required for the drawing | Why it matters |
|---|---|---|
| Curve | Supplier's specified span, rise, radius or template information | Separates similar-looking arch families |
| Angled top | Both side heights and required angle information | Avoids assuming equal legs or symmetry |
| Left/right orientation | Explicit interior or exterior view | Prevents a mirrored order |
| Frame and glass outlines | Both shown or dimensioned as applicable | Reveals the visible border |
| Adjacent rectangular units | Shared alignment references | Coordinates the entire composition |
Andersen's sizing resources demonstrate the need to distinguish unit, rough-opening and other perimeter dimensions. The selected specialty supplier's process should govern the final measurements and template, including any additional information its shape requires.
A homeowner can prepare photographs and approximate dimensions to explain the design. The release for manufacture should follow the agreed field verification. Do not convert a concept drawing directly into an order simply because the overall width appears correct.

How a Project Runs
- 1
Tell us about the project
Send your location, the approximate number of openings, and what you want to improve.
- 2
Review the openings and options
We discuss your priorities and assess the details that affect product selection and installation.
- 3
Define the work in writing
The proposal identifies the products and agreed installation scope so you can understand what the project includes.
- 4
Install and review the result
At completion, we review the installed products, operation, visible finish, and care information with you.

Use one approval drawing as the reference
Custom geometry needs a single clear record of what is being ordered. The drawing should show the viewing direction, overall frame dimensions, shape, divisions, finish and any operating sections. If a radius or angle defines the design, it should be identified in the supplier's required format.
Ask which information is final and which remains preliminary. A design sketch can communicate a concept without being suitable for manufacturing. Labeling those stages prevents an early illustration from being mistaken for the approved order.
When a revision is made, update the drawing and record the change. A different frame profile can alter the visible glass even when the outside size stays the same. A new glass package may affect other specifications. Every related choice should remain coordinated rather than being changed in separate email fragments.

Coordinate a group of shapes as one composition
A custom shape often sits above or beside more conventional windows. The visual connection between them can be more important than the shape alone. Look at perimeter frame widths, mullions, meeting rails, window grid patterns and the spacing between units.
For an arched transom over a rectangular window, ask how the frames join or separate and whether the glass appearance will match. If the lower window operates, its sash profile may differ from the fixed upper section. That can be an intentional design, but it should be visible on the elevation.
Where multiple shapes follow a roofline, review the grouping from inside and outside. Interior ceiling planes may hide parts of an opening that look prominent on the exterior. A coordinated drawing helps avoid a result that works from one side of the wall but feels misaligned from the other.

Distinguish shape from operation
An unusual outline does not tell you whether the window opens. Many architectural shapes are fixed; operable specialty configurations depend on the actual product. Do not assume a custom triangle or arch provides ventilation because a nearby rectangular window does.
If the room needs an opening function, plan it explicitly. You might combine fixed specialty glass with a suitable operable unit below or beside it. The available clear opening, reach, screen arrangement and required room functions need review for that combination.
A high architectural window also needs a realistic operating plan if it is intended to open. Manual controls may not be reachable from the floor, and any special operator needs confirmed availability, access and service documentation. A decorative location should not turn routine operation into an improvised task.
06 of 10
Select glass across the entire design
Custom-shaped glass still needs a deliberate performance and appearance choice from the available glass options. For sun-exposed areas, discuss unwanted solar heat and glare alongside daylight. For an entry or stair, privacy may be as important as an outward view. The shape does not determine those properties.
Ask for the whole-product performance information applicable to the proposed configuration, along with the glass description. A rating for a standard rectangular unit is not automatically evidence for every custom arrangement. If documentation has limits, make those limits clear in the comparison.
Matching new specialty glass to existing nearby panes may require a sample review. Tint, reflectance and the appearance of coatings can become noticeable when units sit directly beside each other. A nominally clear product is not a guarantee of a visually identical match to an older window.
For decorative glass, confirm the pattern orientation and the way it meets the shape edges. A design that looks balanced in a square sample may be cropped awkwardly in a narrow triangle or curved segment. A pattern drawing can be as valuable as the frame drawing.
07 of 10
Plan access for cleaning and future service
Architectural windows are frequently placed where ordinary reach is difficult. The interior may be above a stair, a tall entry or a sloped ceiling. Outside, access may be limited by a roof, landscaping or the height of the wall.
Discuss cleaning from both sides before committing to the arrangement. Do not assume that a custom shape is accessible because the lower window in the group can open. Fixed upper panes and their surrounding frames may need a separate cleaning method.
Keep the approved dimensions, shape template and product information after installation. If the glass or another component requires attention later, those records help establish what exists. A future replacement can become more complicated if the only record is a photograph of a shape with unknown dimensions.
08 of 10
Define the opening work separately from the product
Replacing an existing custom window within an established opening is different from cutting a new shape into the wall. The latter is closer to new-construction window work and can affect framing, exterior finish and other building systems. Those responsibilities should be identified before a window order commits the project to one geometry.
Even an apparently matching replacement needs assessment. The existing frame may hide damage or may not provide an appropriate base for the proposed method. Water management must fit the shaped opening and selected product rather than relying on a generic bead of sealant around a curved edge.
Ask how stucco, trim, drywall and paint meet the new frame. Curved and angled finishes can require a different approach from a straight rectangular surround. The proposal should describe the included finish standard and identify any work handled separately.
If permit, design or association review applies, use the approved elevation and product information in the submission. Our guides to window replacement permits and HOA approval for replacement windows outline what to expect. A picture of a similar window may not describe the actual change being requested. Ordering should follow the agreed sequence for resolving those requirements.
09 of 10
Control revisions at the shape-to-order handoff
Give the final drawing a revision identifier and keep a short change record. The useful question is not only whether the latest file was approved, but whether every linked choice still describes that file.
Suppose an illustrative arched transom changes to a narrower frame profile after the first design review. The outside frame shape may remain similar while the visible glass boundary changes. Decorative pattern cropping, alignment with the rectangular unit below and the surrounding trim may need another look. A revised glass package can create a separate appearance issue even if the geometry stays unchanged.
Before release, compare the drawing against four records: field dimensions or template, product specification, glass/pattern selection and perimeter finish scope. Mark unresolved items as open decisions with a named person responsible for the answer. Release follows resolution of those items and any required project approvals.
After delivery, compare product identification and geometry with the approved revision before installation commits the surrounding finishes. A discrepancy should be resolved through the project process rather than trimmed around to resemble the concept. Preserve the installed revision and order identification for future glass or service questions; superseded sketches should remain clearly labeled.

Compare custom-window proposals by what they resolve
A useful estimate identifies more than a custom-size surcharge. It names the proposed geometry, product construction, glass, joining method, installation approach and finish work. It should also explain who verifies dimensions and how the final drawing is approved.
Ask what happens if a measurement, supplier limitation or concealed opening condition requires a design revision. The answer should distinguish a pre-order change from a change after production begins. Custom work needs a clear decision point because later revisions may affect multiple parts of the project.
Before you request an estimate, gather interior and exterior photos, approximate dimensions and any existing plans. Mark which windows remain and which are part of the proposed group. We can then focus the discussion on the actual shape and its relationships rather than starting with a generic product catalog.
things people ask us
Frequently Asked Questions
Is a custom-sized rectangular window an architectural window?
It can be custom ordered, but this page focuses on nonstandard geometry and coordinated shape arrangements. A rectangular fixed window usually belongs with picture windows. Identifying the actual design problem helps avoid making a straightforward size selection more complicated than necessary.
Can a new arch exactly match my existing arch?
A close match requires verified geometry, frame profiles and opening conditions. Photographs alone are not enough. Ask for the supplier’s required measurements or template process and review the finished frame and visible-glass outlines on the approval drawing.
Can shaped windows open?
Some specialty products can operate, while many shaped units are fixed. Availability depends on the exact configuration. If ventilation or another opening function matters, state it at the beginning so the design includes a supported operating solution.
Why do custom windows need a separate drawing approval?
A verbal description can leave curves, angles, orientation and frame divisions ambiguous. The approved drawing ties those details to the order. It also gives the homeowner and installer a common reference for checking that the delivered product matches the intended design.
Should I keep the template after installation?
Keep whatever final template, drawing and product documentation the project provides, along with the order information. Those records can help with later glass or component questions. They should describe the installed assembly, not an early concept that changed before production.
Can matching arch widths still produce different shapes?
Yes. Span alone does not establish the curve. Rise, radius or the supplier’s required template information can distinguish different arches with the same width. Confirm the measured reference edge and viewing direction before approving the manufacturing drawing.
