Interior Design

Commercial interior design works when it starts from one question: what does this space need to do? We treat layout, light and material as tools with a job to perform, not decoration added once the plan is set. Our commercial interior design services cover workplace interior design, retail fit-outs and public sector buildings, each one shaped around how the space gets used. As part of a wider multi-disciplinary consultancy, we design with structure, budget and delivery already in the room.

What sets us apart in commercial interior design

Our team has sat on both sides of a fit-out: designing spaces and building them. That means we draw details a contractor can build on site, at the tolerances real materials allow. We explain our thinking in plain language too so budget and programme decisions get made early, not three weeks before completion, buried in a variation order.

Layout and space planning

Spatial intelligence shapes every office interior design brief

Every layout we design starts with how people move through a building: entrances, pinch points, desk density and the corners nobody planned for. Getting this right shapes footfall and flow across the working day, before a single finish gets picked. The British Council for Offices now recommends around 10 square metres per person for general workspace, up from 8 square metres, a shift that reflects hybrid work and denser shared space. Get the layout wrong at concept stage, and no finish chosen later corrects it.


Material choice and lifecycle

Sustainable thinking runs through our commercial interior design services

Sustainability in commercial interior design works best woven through the project, not added at the end. Material choice and lighting decisions shape how a space performs in ten years, not just on the day it opens. We draw on our wider net zero and sustainability expertise, so carbon and lifecycle costs are weighed up at concept stage, when changing course still costs little. Materials chosen without that thinking tend to get replaced sooner, and every replacement carries its own carbon cost as well as its price tag.

Commercial interior design work in practice

Building regulations approval is the legal sign off that confirms your design meets UK rules on safety, structure, energy use and access. As a building regulations consultant, we handle Approved Document compliance and Building Safety Act gateways, so your application keeps moving. Our building control consultant team builds in fire safety, structure, access and energy from the start. That way, your sign off and your green goals get sorted together, not one after the other.

Detailed design is the stage where an approved concept becomes drawings and specifications a builder can actually use. We work through the junctions, the wall build-ups, the fire strategy and the coordination between structural, mechanical and electrical design, so nothing gets left for site to sort out. Done properly, it’s the difference between a scheme that prices accurately and one that runs into redesign once construction has started. That’s the work we focus on.

Our master planning services turn a site’s constraints into a plan that can actually be built. A masterplan has to work twice over: once as a design, and again as a case that stands up to a planning committee. Most schemes that stall didn’t lack ambition. They lacked the groundwork underneath it. We build a site masterplan on evidence gathered early, from surveys to policy checks, so it still holds up from first sketch through to the final RIBA stage.

We’re planning consultants, and we know a scheme succeeds or fails on its paperwork as much as its design. We prepare planning applications with that in mind: architects, engineers and specialists working from the same brief, under one roof. From first sketch to final decision, we manage the documents, brief the specialists and deal directly with your council on your behalf, so you don’t have to.

Sustainable architecture design sits at the heart of every building we make at Morson Praxis. We treat low carbon architecture as a core skill, not something added near the end. Buildings cause a quarter of the UK’s greenhouse gas emissions, so the decisions made at concept stage carry real weight. Good sustainable building design gets those early decisions right, from the first sketch through to handover.

A drawing shows you where the walls go. Architectural visualisation shows you what it will feel like to walk through the door. We build photorealistic CGIs, animations and walkthroughs that turn technical drawings into something anyone can follow. Clients, planners and communities get to see a scheme long before a brick is laid, which means fewer surprises and more confidence at every stage that follows.

Understanding commercial interior design

 A few common questions on commercial interior design, answered plainly.

Commercial interior design is the planning of layout, lighting, materials and finishes for spaces used by businesses rather than homeowners, covering offices, shops, hotels and public buildings. It spans spatial planning and furniture selection through to acoustics, signage and how a brand is expressed through colour and material choice.

Office interior design costs are usually quoted per square metre once a brief is confirmed. They vary with scope, location and finish quality. A full workplace interior design project, covering layout, furniture, lighting and finishes, costs more than a light refresh of an existing space.

Timescales are dependent on scale, complexity and whether the building needs planning consent or structural work alongside the fit-out. A single floor of office interior design might take a few months from concept to completion; a full building fit-out takes considerably longer.

An architect is not always a legal requirement for workplace interior design, but is strongly recommended where the work involves structural changes, fire compartmentation or building regulations. Involving an architect early tends to avoid costly redesigns later, particularly on multi-tenanted or listed buildings.

Interior design is the planning stage: layout, material choice, lighting and how a space should function and feel. Interior fit-out is the physical construction that follows, installing partitions, services, flooring and finishes. Commercial interior design services often cover both stages under one team.
