CARLO Compact Backyard House: Sizing & Cost

A 110.22 sq ft footprint sounds generous until you stand inside it. This page splits the CARLO K10-N12 into the two numbers that decide a backyard project — the land it occupies and the area you actually live in — so you can tell whether a small backyard guest house fits the corner of your lot, and whether the finished backyard living quarters should be self-contained or sleep-only.

Framing

What Counts as Compact

Everything on this page sits in one band: a single-room structure that occupies roughly under 150 sq ft of land and holds one open interior volume. Inside that band, buyers are really running two different projects, and the vocabulary matters because it changes what you have to build on site.

Self-contained

Sleep, wash and cook in one envelope

The unit has to carry a wet area and a cooking zone, so plumbing and ventilation routes are planned before it ships.

  • Room for a compact bathroom and a mini kitchen
  • A wet-area route planned before assembly
  • Higher entry price and more site work
Auxiliary

Sleep, work or host only

A single open room used as a bedroom, studio or guest space, with daily needs handled in the main house.

  • No plumbing route required
  • Distance to the main house bathroom is the key check
  • Fastest to deploy and lowest entry price

Footprint Reality: Usable Area vs. Land Occupied

Two sets of numbers describe the same building, and buyers routinely mix them up. The external figure tells you whether it fits the space you have. The internal figure tells you whether you can live in it. Both are listed below exactly as published for the N12.

External dimension10.50′ × 10.50′ × 10.37′
Land occupation110.22 sq ft
Internal dimension10.04′ × 10.04′ × 7.55′
Usable area9.3㎡

If your prepared pad is tighter than roughly 120 sq ft, this is the unit to plan around — and that pad also has to carry the delivery approach, not just the building.

01

Bed only

A double bed plus circulation. This leaves the most floor free for storage, and it is the layout most guests expect from a sleep-only unit.

02

Bed + desk

The home-office layout. Panoramic windows on the long wall keep the desk side bright through the working day.

03

Bed + bath

The self-contained layout. It requires the bathroom option (+$999.00) and a wet-area route fixed before assembly.

Reading the Model Names

Several labels appear across the catalogue for the same building. Match the page you land on, not the label, before you compare anything.

The Real Number: Base Price Plus What You Add

The $9,999 figure is the starting point, not the finished project. Here is the ladder, with a hard line between what the builder prices and what your site prices.

Budget the builder portion first, then price the pad, the power connection and the delivery approach separately with your own contractors. Those three are the lines that move most, and they move for reasons a structure price cannot predict.

Decision Shortcuts by Constraint

Start from the thing that is actually limiting you, not from the model list. Each path below pairs a real constraint with the specification that answers it.

Constraint — tight lot

You have one corner and nothing else

The K10-N12 occupies 110.22 sq ft on a 10.50′ square external footprint, with a 10.04′ internal span.

Decision: measure the pad and the route a delivery vehicle can reach before you order. A footprint that fits but cannot be delivered to still stalls the project.

Check the K10-N12 dimensions
Constraint — year-round climate

It has to be usable in every season

The structure uses aluminum-zinc coated exterior panels over a built-in polyurethane insulation core, with a pitched roof.

Decision: add the day and night curtain (+$129.00) so the glazing can be shaded in summer and closed down in winter.

Constraint — guests need a bathroom

Nobody should cross the yard at night

The interior can be laid out as a bedroom, bathroom, mini kitchen or living area, and the layout can be adjusted before assembly.

Decision: select the bathroom option (+$999.00) and settle the drain and vent route with your installer at the same time as the pad.

Review the bathroom option
Constraint — income or work use

It needs to pay for itself

The K10-N12 is positioned for guest house, short-term rental, private lodging and home office use, with panoramic windows on the open side.

Decision: fix the interior layout before the order ships — post-delivery changes cost more than the ones agreed at order stage.

Assembly & Timeline: Who Actually Does the Work

The structure arrives as a split modular system rather than a construction site. No professional construction expertise is required — the work is a prepared base, a delivery, and a join.

1

Prepare the site

A level pad and a clear approach. This is the only stage that involves third parties, and it happens before delivery.

2

Deliver the modules

Because the unit is factory-built, site disruption stays short and materials are not stockpiled in your yard.

3

Two people join the modules

Assembly is measured in hours, not weeks, using basic tools — not a contractor crew.

4

Connect and finish

Electrical tie-in, then the soft furnishings you selected, including the bathroom unit and curtains.

Get a Quote for Your Yard

Send us your prepared pad dimensions, whether you need the bathroom or curtain option, and how a delivery vehicle reaches the site. Trade partners and multi-unit orders can ask about customization and bulk pricing at the same time — the sooner the layout is fixed, the fewer changes after delivery.

is it suitable for year-round use?

the structure uses aluminum-zinc coated exterior panels for corrosion resistance, over a built-in polyurethane insulation core, with a pitched roof. that construction is intended for temperature stability across seasons; add the day and night curtain to control light and privacy through the glazing.

can the interior be arranged as a bedroom, bathroom or mini kitchen?

yes. the interior layout is flexible and can serve as a bedroom, bathroom, mini kitchen or living area, and adjustments can be made before assembly. wet areas such as the bathroom should be planned with your installer before the unit ships.

how do i choose between the k10-n11, k10-n12 and k10-n24?

they are separate models, each with its own product page listing its own footprint, capacity and price. compare those figures against the pad you actually have. the figures on this page describe the k10-n12 only and should not be applied to the other two.
