Interior Architecture
Our interior architecture services bridge the gap between traditional architecture and interior design. From early-stage planning to the reconfiguration of interior spaces, we ensure that the inside of your building is as sustainable, functional and aesthetically pleasing as the exterior - all while adhering to the correct building regulations.
Working collaboratively with a range of specialist consultants, we focus on efficient space planning, optimised layouts, structural elements such as staircases and doors, material selection and the coordination of systems for heating, cooling and ventilation.
When done well, interior architecture enhances the functionality, value and overall design of a property, while helping to reduce ongoing running costs. Our expert architects will guide you through every step. Whether you’re looking to optimise your home or undertaking an office fit out, we’re here to help bring your vision to life with sustainability at its core.
Our Interior Architecture Services
At marsh:grochowski, we’ve been delivering interior architecture services for many years. Our award-winning team knows how to make interior environments safe, sustainable and highly functional - all while staying true to your aesthetic ambitions.
From residential spaces to commercial workplaces, we use technical design and 3D visualisation to enhance every aspect of your interiors, from floor to ceiling and everything in between.
Residential Interior Architecture
Residential interior architecture goes far beyond decoration. We assess your space through an architectural lens, focusing on structure (including the placement of walls, windows and HVAC systems), sustainability, code compliance and safety. The result is a human-centred design that responds to your lifestyle.
We then collaborate closely with contractors and structural engineers to turn the design into reality.
Commercial Interior Architecture
Similarly, commercial interior architecture aims to create spaces that support the goals of your organisation, with emphasis on operational needs, safety codes and how people interact within the environment. This can include offices, retail spaces, hospitality settings and industrial environments.
A well-designed commercial interior considers branding, functionality, technology and sustainability to create an inclusive, productive and engaging space.
Concept Development and 3D Visualisation
Concept development and 3D visualisation are two distinct but complementary phases of interior architecture, and together they transform your ideas into a tangible vision.
During concept development, we explore your needs, analyse the building’s context and condition and begin to define the narrative of your interior, with a strong focus on sustainable design principles.
Through 3D visualisation, we then create realistic digital models to show how your space will look before any work begins. Using specialist software, we can incorporate details such as lighting and texture to give you a clear and accurate representation
