Mansion house plans over 300 m²: compare layouts, garages and basements

 Every single house plan over 300 sqm in our catalog has been meticulously crafted by a certified architect with over 30 years of professional experience. AkvilonPro architectural studio operates fully legally, providing an official design license with every blue print set.

Mansion house plans may look similar when compared by total floor area, but the allocation of that space can be very different. This selection of large homes ranges from 302 to 441 m² and includes designs with garages, basements and attic floors. Check the individual floor plans before deciding which layout suits your brief.

If a smaller house would meet your needs, compare the house plans for 200–300 m² homes as well.

What distinguishes the designs in this category

Some houses have a full upper storey, while others use an attic floor. Garages and basements are present in individual designs, but their arrangement and area vary. A category-wide description cannot replace checking the room schedule for a particular house.

In Khodosivka, the 302 m² total includes a 40.9 m² garage; Vyshenka has a 20.5 m² garage and a 100.4 m² basement within its 350 m² total, so the overall figures conceal significant differences in usable room space.

How to assess a larger floor plan

• Shared and private rooms. Check the actual rooms and their areas against the household's requirements instead of inferring them from the size of the house.
• Use of each level. Examine the ground floor, upper storey, attic floor and basement where applicable. Their functions are not interchangeable.
• Garage and basement space. Identify these areas separately from the rooms intended for everyday living.
• Plot and engineering requirements. Check building dimensions against the proposed site. Any foundation review or engineering changes need to be considered for the individual design and site information.

Adapting a ready-made house design

A ready-made design is a sensible starting point when most of the room arrangement already meets the brief. Increasing the living room area, adding a bathroom beside a bedroom or changing the roof height can be discussed with the architect. These are possible design requests, not guaranteed modifications: the structural and engineering implications must be assessed before any change is approved.

AkvilonPro's architectural work is associated with Oleksiy Biryukovych, who has more than 45 years of practice and over 500 completed projects. The scope of adaptation is determined from the selected drawings.

Questions about the collection

What floor areas are covered?

From 302 to 441 m² in total. Where present, garages and basements can contribute substantially to that figure, so compare the room schedules as well.

Are any houses designed with garages?

Yes. Khodosivka includes a 40.9 m² garage, while Vyshenka has a 20.5 m² garage. Not every design provides the same facilities.

Can a ready-made plan be changed?

Changes can be considered for a specific design. The architect checks whether the proposed revisions affect the structure, layout or building services before defining the scope.

Choosing the right type of project

Compare the floor plans with your list of rooms and the dimensions of your plot. If the brief centres on guest accommodation as a business rather than a private house, look at the mini-hotel projects separately. For a chosen home, discuss any adaptation with the architect.
