Changing Finishes and Upgrades During Construction: How Sienna Handles Buyer Change Orders Before Handover

Yes, you can change finishes and upgrade your Sienna villa during construction — but each decision has a cut-off milestone tied to the build sequence, and the sooner you lock a choice, the cheaper and cleaner it is. Cosmetic selections (tile, cabinetry, fixtures) stay open longest; anything structural or system-level (layout, plumbing routes, solar sizing) closes early. A written, priced change order documents every modification before any trade touches it.

The Short Version

• Finish selections (tile, countertops, cabinetry, paint, fixtures) can change until the trade for that element is scheduled — usually the latest cut-off.
• Layout and structural changes (moving walls, adding a room, relocating plumbing) close early, before foundations and rough-in.
• Every change is a written, priced change order you approve before work proceeds — no verbal agreements, no surprise invoices.
• Upgrades beyond the base spec are added cost; swaps within the same price tier are often cost-neutral.
• Earlier decisions are cheaper. A change requested after a trade has finished means demolition plus rebuild — the most expensive way to customize.

What Is a Change Order on a Pre-Construction Villa?

A change order is a written, priced agreement to modify your villa's specification after the construction contract is signed but before handover. It documents exactly what changes, what it costs, and how it affects the timeline.

Here's how that works at Sienna. When you sign, you're agreeing to a defined specification — floor plan, finish schedule, systems, and the materials behind each. A change order amends that spec in writing. The point is protection on both sides: you know the price before work starts, and the build team knows exactly what you approved before a trade shows up. Nothing moves on a handshake.

Why writing it down matters more than it sounds

Verbal requests on a tropical construction site get lost in translation — literally, across English, French, Spanish, and German crews. A documented change order removes ambiguity. It also feeds your villa handover documents, so the as-built records match what you actually paid for. That paper trail is what protects your resale value later.

When Can You Change Finishes and Layouts During the Build?

It depends entirely on where that element sits in the construction sequence — and the sequence is the whole game. You customize against the build, not against the calendar.

Think of construction as a one-way assembly line. Decisions that happen first (foundations, framing, plumbing and electrical rough-in) have the earliest cut-offs because everything after depends on them. Decisions that happen last (tile, paint, cabinetry, light fixtures) stay open the longest, because they're installed near the end.

The three tiers of change

1. Structural and layout — moving or adding walls, changing the footprint, relocating a bathroom. These close first. Once foundations are poured and rough-in begins, reopening them means demolition.
2. Systems — plumbing routes, electrical circuits, solar sizing, air-conditioning zones. These close at rough-in. A relocated kitchen island isn't just a countertop; it's water, drainage, and power.
3. Finishes and fixtures — tile, countertops, cabinetry, paint, taps, lighting. These stay open until the trade for each is scheduled. This is where most buyers make their changes, and it's the easiest tier to get right.

The cheapest change order is the one you make on paper before a single trade arrives. The most expensive is the one that requires undoing finished work.

If you're still weighing which layout suits how you'll actually use the villa, comparing two Sienna floor plans side by side is worth doing before you lock the structural tier.

How Much Do Villa Upgrades Cost at Sienna?

Upgrades beyond the base specification are added cost; lateral swaps within the same material tier are frequently cost-neutral. The variable isn't just the material — it's whether the change touches trades that have already worked.

Say you're choosing between two porcelain tiles in the same price band. Swap one for the other before the tiler is scheduled, and the cost difference is often zero. Now upgrade to an imported natural stone, and you're paying the material premium plus any extra labour. Request that same stone after the original tile is laid, and you add demolition and disposal on top.

What drives the price of a change

The rule holds across every row: the earlier the decision, the smaller the invoice. Furnishing choices follow a similar logic — if you're deciding between local and imported options for your villa, the lead time on imports is often the deciding factor, not the price alone.

What Can't You Change?

Some elements are fixed because they protect the whole development, not just your villa — and these sit outside the change-order process entirely. This is the part buyers sometimes don't expect.

Sienna's building guidelines govern what every villa can and can't do, so that no single owner's choice damages the shared character or resale value of the neighbourhood. The 40 cm roof cap and other design rules are the clearest example: roof heights, earth-tone palettes, and setbacks are set at the community level. You can't paint a villa brilliant white, and that's deliberate — white walls are banned at Sienna precisely so the hillside reads as one landscape rather than a row of competing houses.

These guidelines are part of the broader framework covered in our complete guide to Sienna's amenities and community. Within those boundaries, you have wide latitude — earth-tone palettes still leave you dozens of finish combinations. Outside them, the answer is a firm no, and it's no for your protection as much as your neighbour's.

Environmental and structural limits

Elevation, slope, and the site's environmental obligations also constrain certain changes. A villa on a steeper El Jamito lot may have foundation and drainage requirements that rule out specific layout moves. These aren't arbitrary — they're tied to the same site-vetting that keeps the development stable on a hillside at 150–300m elevation.

How Does the Change Order Process Actually Run?

You request it, the team prices it, you approve it in writing, and only then does the build team schedule the work. Four steps, no shortcuts.

In practice, the flow looks like this:

1. Request — you raise the change with your project contact, ideally through your owner portal so there's a timestamp.
2. Pricing and timeline — the team returns a written quote: material cost, labour, and any effect on the schedule.
3. Approval — you sign off. Nothing proceeds until you do.
4. Execution — the change is folded into the build sequence and reflected in your as-built documentation.

Where the owner portal fits

Because most of our buyers are abroad — in Montreal, Munich, or New York — the portal matters. It gives you milestone visibility and a written record of every approved change, so you're not relying on memory or a WhatsApp thread six months later. That transparency is the same system that carries you into your first 90 days as a Sienna owner after handover.

Frequently Asked Questions

Can I upgrade my villa's finishes if I'm buying from abroad?

Yes. The change-order process runs through your owner portal and your project contact, so you approve finish selections and upgrades in writing without flying in. Many buyers never visit the site mid-build and still customize fully — the documented, priced quote is what you're approving, not a verbal site conversation.

What happens if I miss a finish cut-off?

The element gets installed to the base specification, because the trade can't wait on an open decision without stalling the whole sequence. You can still change it later, but it becomes a post-installation change order — demolition plus redo — which is the most expensive route. Deciding early is always cheaper.

Do upgrades affect my villa's CONFOTUR treatment?

Upgrades Sienna builds and delivers remain part of what the developer constructs, which is the scope CONFOTUR's provisional status under Resolution 203-2024 is designed to cover. The classification is still provisional — the definitive resolution was filed in July 2026 and is pending — so treat this as general information and confirm specifics with the legal team for your file.

Can I add solar capacity as a change order?

Yes, within the structural and drainage limits of your lot and the roof-cap design rules. Solar sizing is a systems-tier decision, so it closes at rough-in rather than at the finishes stage — plan it early. Our guide to sizing a solar system for a DR villa covers the roof-area constraints that shape what's possible.

Is there a limit to how many change orders I can make?

There's no fixed cap, but each one must clear its sequence cut-off. Cluster your decisions early rather than drip-feeding changes — a dozen finish tweaks submitted before the finishing trades are scheduled is routine; the same dozen requested one at a time over the final weeks creates scheduling friction and cost.

The Bottom Line

Customizing a new-build villa at Sienna is straightforward when you work with the build sequence instead of against it: lock structural and systems choices early, keep finish decisions moving before each trade is scheduled, and get every change priced in writing first. The cut-offs aren't bureaucracy — they're what keeps your villa on time and your invoice predictable. Ready to walk the layouts and finish options in person?
