Architectural Design
& Planning Services
At MARSH & CO., we bridge the gap between creative interior design and structural architecture. We don't just design rooms; we redefine how you live within your home. Our comprehensive architectural service manages the entire process—from feasibility studies and local authority planning applications to detailed building regulations and project oversight
-
We begin with a site analysis to explore the potential of your property. Whether it’s a modern glass-roofed extension or a complex barn conversion, we produce initial sketches and 3D models to help you visualise the volume and flow of your new space.
-
Navigating local planning authorities in Sheffield, Barnsley, and the surrounding areas can be complex. We handle the submission of all necessary drawings and documents, specialising in:
Householder Planning Applications
Lawful Development Certificates (Permitted Development)
Listed Building Consent for heritage properties.

Once planning is secured, we produce the technical drawing packages required for Building Control approval. We work closely with structural engineers and contractors to ensure every detail meets UK safety standards without compromising on design aesthetics.

Most architects stop at the "shell." Because our background is in high-end interiors, we design from the inside out. We consider where your bespoke wine storage will sit, how the lighting will hit your velvet upholstery, and where the floor-to-ceiling glazing should be positioned to maximize your views—all before the planning application is even submitted.
Photo Realistic Visuals
Where your design concepts come to life with stunning realism. Our state-of-the-art technology creates detailed, lifelike representations of your project, providing a vivid preview of the finished space. Immerse yourself in the vision and make informed decisions with confidence, as you witness your ideas take shape in unprecedented detail.
Space Planning 2D & 3D Floor Plans
Floor planning is essential in interior design, providing a foundation for functional and attractive spaces. A well-designed floor plan optimises space use, allows for effective movement, and meets occupants' needs. It guides furniture and fixture placement, ensuring efficiency and enhancing visual appeal.
