Design of houses

House Interior Design as an Architectural Discipline

At Koshulynskyy & Mayer, interior design is first and foremost an architectural act. We do not decorate surfaces — we construct systems. Planning logic, the rhythm of light, material balance, and proportional clarity define every project. A house is understood as a coherent structure where each element serves a unified concept.

Contemporary house interior design must respond not only to aesthetic expectations but also to long-term living scenarios. A well-designed space should function with relevance five, ten, even fifteen years ahead — remaining adaptable, refined, and enduring.

A Space That Reflects Lifestyle

Every house interior project begins with contextual analysis: architecture, landscape, orientation, and the lifestyle of its owners. We work with generous volumes, double-height living areas, open-plan layouts, and the integration of terraces and courtyards.

Cottage interior design extends beyond organizing rooms; it establishes a dialogue between interior and environment. Panoramic glazing, open sightlines, natural daylight, and authentic materials create a seamless connection to the landscape.

In our projects, stone, wood, metal, and textiles are not decorative accents — they shape the architectural identity of the space.

Full-Cycle House Design Process

Professional interior design for private houses includes:

  • functional planning development

  • spatial zoning and hierarchy

  • natural and artificial lighting strategy

  • material and texture specification

  • 3D visualizations

  • comprehensive technical documentation

  • author supervision during construction

Detailed documentation forms the foundation of precise execution. It ensures budget control, construction accuracy, and full alignment between the original concept and the final result.

Intelligent Luxury Without Excess

We perceive luxury as a strategic quality. It reveals itself through clarity of planning, material integrity, proportional precision, and balanced light. In cottage interior design, there is no room for accidental decisions — every detail supports the architectural composition.

A house should offer stability and a sense of quiet confidence. This is where true spatial value resides.

Timeline and Investment

The development of a house interior design project typically takes between one and three months, depending on size, architectural complexity, and the level of customization.

The cost of interior design for houses is calculated individually and depends on:

  • property size

  • scope of technical documentation

  • number of bespoke elements

  • level of author supervision required

We maintain full financial transparency and provide detailed cost breakdowns at every stage of collaboration.

Interior Design for Private Houses and Villas

Architectural Approach by Koshulynskyy & Mayer

Interior design for private houses is not about decoration. It is a strategic architectural process that defines how a space functions, feels, and evolves over time.

At Koshulynskyy & Mayer, we approach every house as a complete spatial system. The goal is clarity, proportion, functionality, and long-term relevance.

Our Philosophy of House Interior Design

Individual Approach

Each house interior design project is developed based on the client’s lifestyle, daily routines, and long-term vision.

Integration with Landscape

We design houses that connect architecture, interior, and surroundings. Panoramic glazing, terraces, natural light orientation, and outdoor transitions are carefully considered.

Strategic Luxury

Luxury is not excess. It is precision. Every element serves a purpose, and the overall space remains balanced and timeless.
