Commonly Asked Questions

FAQs

What does a fit-out service involve?

A fit-out service typically includes both Cat A and Cat B fit-outs. Basic fixtures are provided in a Cat A fit-out, creating a blank canvas. Meanwhile, a Cat B fit-out selectively styles the interior with the end user in mind.

What makes a commercial fit-out different from traditional services?

Commercial fit-outs stand out from traditional services due to their customisation for specific sectors and niches that are not available through residential offerings. Healthcare, hospitality, workspaces, and education fit-outs each have unique requirements, which can only be managed by a trusted commercial fit-out contractor.

How much does a commercial fit-out cost?

The cost of a fit-out takes into account various factors, such as square footage, the brief, and the end-user. A straightforward answer to this question isn’t possible. However, at Ultimate Interiors, close collaboration with you ensures needs are met within your budget, utilising trusted expert designers and architects.

How long does a commercial fit-out take?

The timeline for a commercial fit-out depends on several factors, including the size of the space, the complexity of the design, the type of fit-out (Category A vs. Category B), and the approvals required.

Because each project is unique, we can only provide an accurate timeline once we have a clear brief, budget, and scope of work. Our team then applies proven planning formulas to give you a tailored and realistic schedule.

Will the fit-out disrupt my business operations?

Fit-outs can cause a degree of disruption, but the impact largely depends on whether the premises are occupied during the works. If the space is vacant, the process is usually straightforward.

Suppose your team is already operating in the premises. In that case, we plan to work in phases, schedule noisier activities outside regular working hours, and coordinate closely with your staff to minimise disruption. Our aim is always to keep your business running as smoothly as possible throughout the transformation.
