Dear Archive,

Below are Stela’s answers to the fit-out questions owners ask most often — boiler, bathroom, underfloor heating, kitchen, flooring and doors — gathered together as one reference.

---

Stela is your main point of contact for fit-out choices, deadlines and tracking — the fastest way to confirm any of the categories above.

---

The official boiler options are listed under Category 20 — Water Heater (Boiler) — in the Fit-Out Choices spreadsheet, which sets out the standard specification and the available upgrade options, including Wi-Fi-enabled alternatives.

For your final apartment selection, please use this same spreadsheet — also linked from the Owners Fit-Out Choices page.

Once the file is open, press Ctrl+F / Cmd+F and type “Category 20” to jump straight to the boiler section.

The value of the Standard A boiler is credited, so an owner selecting an upgrade pays the applicable upgrade difference rather than paying for both boilers.

Owners requesting a different boiler solution, including a horizontal Wi-Fi boiler or premium flat boiler, should contact Stela for confirmation of the applicable project price and installation requirements.

The bathrooms are planned for vertical boiler installation as standard.

A small number of apartments are specifically shown in their bathroom layouts with horizontal installation.

Owners can choose between the standard TESY BiLight, the BiLight Cloud Wi-Fi upgrade, a reversible BelliSlimo Lite Cloud for horizontal Wi-Fi installation, or the confirmed premium BelliSlimo Dry 80 option.

*Vertical vs Horizontal Installation: Can be installed horizontally, but the net usable hot-water capacity is approximately 10% lower than in the standard vertical position. Owners who prefer horizontal installation should inform Stela and have this recorded in the Fit-Out Choices spreadsheet.

The standard specification is a TESY BiLight installed vertically in accordance with the planned bathroom layout. Studio — 50 L: €161, One-bedroom — 80 L: €171.

The standard 80 L BiLight has:

• 82 L net tank volume;
• 3000 W power;
• energy class C; and
• approximately 155 L V40 usable mixed hot water.

The B1 upgrade retains the planned vertical installation while adding Wi-Fi / MyTESY smart control. Studio — 50 L: €210, One-bedroom — 80 L: €240. The value of Standard A is credited and the owner pays the applicable upgrade difference.

Wi-Fi functions include:

• remote on/off and temperature management;
• scheduling and operating-status monitoring; and
• smart and energy-saving functions through MyTESY.

Owners who specifically prefer horizontal installation + Wi-Fi can request the reversible BelliSlimo Lite Cloud 50 or 80.

Both are:

• only 28 cm deep;
• energy class B;
• Wi-Fi / MyTESY enabled; and
• designed for vertical or horizontal installation.

The additional project cost for the approved horizontal solution is: +€170

Owners must inform Stela in advance so that the change can be coordinated with the bathroom layout, plumbing and electrical connections.

The confirmed premium project option is: TESY BelliSlimo Dry 80, Model: GCR 80 27 24D E31 EC — Project price: €483.

It provides:

• flat 28 cm design;
• dry heating elements;
• 65 L net tank volume;
• 1200 / 2400 W power;
• energy class B; and
• reversible vertical/horizontal installation.

This model does not have built-in Wi-Fi.

With reversible flat boilers, horizontal installation generally reduces the usable hot-water output — for example:

BelliSlimo Dry 80

• Vertical: approximately 140 L V40
• Horizontal: approximately 105 L V40

BelliSlimo Cloud 80

• Vertical: approximately 140 L V40
• Horizontal: approximately 109 L V40

Vertical installation is therefore preferred where the bathroom layout allows it.

The planned boiler position is shown in the individual bathroom layout/image provided for each apartment.

The general project standard is vertical installation, although some apartments are explicitly shown with horizontal installation.

In those cases, installation follows the position and orientation shown in the apartment layout.

If your bathroom layout shows a vertical boiler but you prefer horizontal installation, please inform Stela in advance.

Find your apartment number in the tables above and open the corresponding image in a new tab. If your apartment is not listed, it follows the general project standard (vertical installation, no separate image needed). Apartments 3, 11, 12, 14, 29, 42, 44, 51, 52, 57, 58 and 61–67 do not yet have a layout image; these are still being prepared and will be issued early next week. We will update this page and follow up with owners of these apartments once the sketches are ready.

The team will check whether this can be accommodated with:

• available wall space;
• plumbing;
• electrical connections;
• vanity/mirror arrangement; and
• other bathroom elements.

Owners selecting horizontal installation should therefore understand that the usable hot-water capacity is generally lower than when the same reversible boiler is installed vertically.

Yes. The confirmed premium boiler option is: TESY BelliSlimo Dry 80, Model: GCR 80 27 24D E31 EC — Project price: €483.

The premium option adds a slim profile, dry heating elements, flexible installation, energy class B and strong heating power.

Where possible, vertical installation is preferable because it provides more usable hot water.

Owners who specifically require Wi-Fi should choose a Cloud model instead, such as BiLight Cloud for vertical installation or BelliSlimo Lite Cloud for a reversible/horizontal Wi-Fi solution.

The project standard is: Studio — 50 L, One-bedroom — 80 L. If a bathtub is chosen, we recommend increasing the available hot-water capacity.

For a studio with a bathtub, we recommend upgrading from the standard 50 L to at least 80 L.

For a one-bedroom apartment with a bathtub, 80 L is the minimum; 100 L is recommended for regular and more comfortable bath use.

TESY offers 100 L options including:

• BiLight 100;
• BiLight Cloud 100; and
• BelliSlimo Cloud 100.

Vertical installation is preferable where possible because reversible flat boilers generally provide more usable mixed hot water vertically than horizontally.

The Fit-Out Choices spreadsheet is the official record for owner selections — also linked from the Owners Fit-Out Choices page.

If Standard A is retained, the standard specification will be installed automatically.

After the applicable deadline, the selection is considered frozen for construction.

Later changes may no longer be technically possible and, where accommodated, may result in additional labour, material and coordination costs.

This depends on the type of change and the current construction stage.

As of 1 August 2026, changes affecting the apartment’s core construction and installations are no longer accepted, including:

• wall positions or apartment layout;
• electrical installations, wiring or electrical points; and
• main water and plumbing installations.

Fit-out and finishing selections that remain open can still be made within their applicable deadlines.

If you have a specific change in mind, please describe it precisely. The team will confirm whether it remains technically possible and advise of any additional cost or programme impact.

The final deadline for the toilet selection is 30 August 2026.

The wall-hung options require the earlier decision because the concealed frame/cistern and associated installation must be coordinated with the bathroom construction.

If no wall-hung option is selected by 30 August, the apartment proceeds with Standard A.

The main bathroom layout and the locations of the water, drainage and electrical installations are fixed.

Each bathroom has two drainage points:

• a linear drain in the shower area; and
• a second floor drain close to the sink/vanity.

These positions cannot be relocated.

A custom lower vanity may be chosen and sourced by the owner, but it must work with the fixed sink, plumbing and drainage positions.

Owners should provide product details, dimensions and installation requirements before purchasing.

The same applies to an owner-supplied:

• mirror;
• mirrored cabinet; or
• upper cabinet above the sink.

This allows the team to coordinate the item with the boiler and other bathroom elements.

We will answer this question next week, there is still some information missing. Thanks for your patience!

The status varies by:

• apartment;
• type of approved change; and
• current construction stage.

Some approved changes have already been physically executed, while others may still be scheduled as part of the ongoing works.

An approved or recorded change should therefore not automatically be assumed to have already been completed on site.

Owners are welcome to:

• visit the site personally and inspect the current status of their apartment; or
• contact Stela, who can carry out an in-person check of the apartment, confirm the status of the requested item and answer questions.

When requesting verification, please identify the specific change or fit-out item you want checked.

The full kitchen catalogue, layouts and available finish options are planned to be shared by the end of August 2026.

Owners may choose a project kitchen or source their own.

An owner-sourced kitchen must be designed around the prepared water, drainage and electrical points, which are fixed.

There is no need to place a kitchen order now. Owners will first receive the full project kitchen information and then have time to review the options before the October–November ordering period.

Owners may supply their own approved laminate, tiles, skirting and other custom fit-out items, subject to coordination with the construction programme and confirmation that the selected materials are suitable for installation.

Final tile installation pricing is indicative and depends on:

• quantity;
• tile dimensions;
• laying pattern; and
• installation requirements.

All owners choosing custom bathroom tiles must inform the Mons Orbelus team and have “Custom Tiles” recorded in the Owners Register by 10 September 2026.

This applies to all floors and allows the site team to plan which bathrooms receive standard versus owner-supplied tiles.

Therefore: by 10 September, all owners choosing custom bathroom tiles must notify the team.

The physical delivery then follows the applicable floor deadline.

For all owner-supplied/custom items, Stela will share the project ordering and logistics procedure by the end of August 2026.

It will cover:

• ordering and supplier coordination;
• site delivery arrangements and time windows;
• apartment/owner labelling;
• receiving and identifying materials on site;
• storage/handling where applicable; and
• coordination with the installation programme.

Owners should wait for Stela’s procedure before arranging delivery to site.

Yes — owners are invited to review the planned opening direction of the interior doors in their apartment and advise us if they have a preferred alternative. Deadline: 25 September 2026.

To request a change:

• use your apartment layout;
• clearly mark the preferred opening direction of the relevant door(s); and
• send the marked layout to Stela by 25 September 2026.

The project team will review the request and accommodate the preferred opening direction where technically possible.

If no alternative is submitted by the deadline, the doors will proceed according to the planned project layout.

---

The next owners’ meeting is on Tuesday, 1 September 2026, at 18:00 (Bansko time).

Further information — including the agenda and joining details — will follow.

---

The Mons Orbelus team will provide the standard project information, fit-out options, deadlines and general instructions required for owners to make their selections.

Where an owner requests individual assistance from Stela in relation to personal choices, custom products, layouts, sourcing, coordination or other owner-specific fit-out matters, this support will be €25/hour, charged individually to the relevant owner.

This may include:

• individual review of custom products or specifications;
• assistance with owner-selected fit-out choices;
• review of owner-supplied items and dimensions;
• individual layout or positioning discussions;
• sourcing or ordering assistance;
• supplier and delivery coordination;
• individual on-site checks requested by the owner; and
• other owner-specific fit-out coordination beyond the standard information provided to all owners.
