6 luxury mansions built in just a few days
Mesmerising flat-pack mansions

You'd be forgiven for thinking building a luxury home take months of planning and years of heavy lifting, when in fact new technology and building innovations mean designer properties can now be pre-built and put together in a matter of days, almost like IKEA furniture.
From a prefabricated mansion in Pacific Palisades to a classical family home in Germany, click or scroll to step inside the world of so-called 'flat-pack mansions'...
Classical-inspired townhouse, Hesse, Germany

One look at this stunning, classical-inspired townhouse and you'd be forgiven for not believing it was constructed using prefabricated panels. But, it was.
The extensive property was the brainchild of homeowner Cat Miller, who, after finding the perfect plot in Hesse, Germany, had approached a range of architects to design a property that combined both classical and modern architectural styles. However, no one was keen to help her until she spoke with timber frame firm, WeberHaus.

Cat worked with WeberHaus to design a modern home, inspired by English architecture and Saltbox timber frame houses found in her native Connecticut. In order to ensure the home suited those surrounding it, the pair opted for a traditional façade, while getting more creative and modern at the rear, where they introduced plenty of glass. Inside, Cat wanted spacious and light-filled rooms that were fit for the whole family.

Once the plans were set, WeberHaus set about crafting the building. They managed the build and, once the foundations were ready, delivered and installed the turnkey kit house. In fact, the exterior parts of the house were finished in just seven days. It took just six more months to complete the internal fit-out, due to the sheer size of the property and the amount of customisation the Millers had requested.
From bespoke carpentry to soaring ceilings, elegant fireplaces, traditional light fixtures and hardwood floors, every room is incredibly beautiful and finished to perfection.

Custom-built mansion, California, USA

This incredible home by Plant Prefab can be found on a beautiful lot in the heart of Santa Monica, California. The eye-catching modern mansion was prefabricated as 11 individual modules and assembled on-site in just two days, saving the neighbours from months of construction noise and disruption.
Offering 4,700 square feet (437sqm) of inside space, the custom-designed home was inspired by architect Ray Kappa's LivingHome 1 model, which was the first home in the world to achieve LEED Platinum certification. With a distinctive mid-century modern aesthetic, the property boasts floor-to-ceiling glass, warm wooden elements and plenty of clean lines, resulting in a contemporary finish with endless wow-factor.

Inside, you'll find four bedrooms, four bathrooms and a striking open-plan living room that spans the entire width of the property. Complete with a lounge, dining zone and luxurious kitchen, this space is defined by its exposed construction materials, centralised concrete fireplace and wall-to-wall sliding doors.
The state-of-the-art kitchen comes equipped with Caesarstone countertops, designer Miele appliances and an open seating area that spills out to the terrace.

As with all Plant Prefab homes, the property was designed with environmental sensitivity in mind, using sustainable construction techniques and materials at every stage.
Upstairs, the tranquil master suite opens out to a private balcony with views to the Pacific Ocean and the low-maintenance backyard that comes kitted out with a plunge pool and raised spa. In 2020, the property landed on the market for the first time and came with a $8.6 million (£6.2m) price tag.

Of course, in order to make the most of the Californian climate, the home also boasts stunning exterior spaces, from which 360-degree views can be savoured.
While the design process takes roughly 12 weeks, the fabrication and site work can be completed in as little as two months. Delivered in factory-made modules, your bespoke home will then be erected on your chosen plot in less than 48 hours, since most Plant homes are shipped 90% complete, with even appliances in place.
If you've fallen in love with the LivingHome 1 model, you can specify a turn-key version for just under $2.3 million (£1.6m) – and we're sure every single penny would be well spent.

Entirely unique, the spectacular spread blends contemporary styling with a more traditional, practical design that's suitable for a busy family.

Many of the interior spaces also open up to sunny patios or shaded balconies, where views of the idyllic garden can be enjoyed.
