Commercial Property Refurbishments for Landlords and Property Owners

Office and Retail Fit-Out Specialists

Commercial properties require a different level of refurbishment expertise than residential: higher-specification building services, complex acoustic and fire compartmentation requirements, the need to maintain building operations where possible and the commercial imperative to complete works on programme and within budget. Advantage Basements & Renovations brings all of these capabilities to commercial refurbishment projects across London.

We refurbish commercial properties for building owners, investors and occupiers across the office, retail and mixed-use sectors – delivering refurbishments that enhance asset value, improve occupier experience and meet the evolving demands of the commercial property market.

Planning Design

  • We'll come to your home or you can drop into our office at 95 East Hill, SW11. This initial meeting will allow us to understand your aspirations, appreciate your requirements and design the space you want. Our surveyor will then discuss your needs and the practicalities of the project. Within days of this initial consultation we will provide a detailed proposal with an estimated budget.

  • Ideas start taking shape. The architectural designs and schematics will give you an accurate picture of how your property will look. When you're happy with the plans and have approved the budget, we can apply for the necessary permissions.

    These are important documents for you. Advantage always appreciate that this is your home and endeavour to minimise the impact the construction has on your life. Our schedule of works gives you detailed and itemised list and costings of key features of your project. We then produce an accurate timetable of what to expect and when that will enable you to accurately monitor progress. Finally we will estimate the amount of each valuation and give you predictions of when these are to fall due.

  • We manage this whole process: structural designs and calculations are drawn up to create a practical blueprint for your new living space and planning consents obtained so the construction can begin. This is the point your ideas take shape. Advantage provides the structural designs and calculations to create a practical blue print for your new living space. When these detailed designs have been approved the job of construction can begin.

  • Our schedule of works gives a detailed and itemised list plus costings for key features and phases. Successful project management is all about communication. Advantage is a tight knit and efficient team and while we're in your home we make sure that you are kept up to date and happy with our progress. Efficient communication avoids problems and delays and is the best way to keep to budget and schedule.

Programme Management and Minimising Disruption During a Commercial Property Refurbishment in London

In commercial settings, works must often be carried out around ongoing building operations, requiring careful phasing, out-of-hours working and close coordination with building management and occupiers. Our project managers develop detailed programmes that manage these constraints effectively, communicate clearly with all stakeholders and ensure that disruption to building operations is kept to an absolute minimum.

Our experience in central London's commercial property sector gives us the understanding and relationships needed to navigate the specific requirements of managed commercial buildings, from security and access protocols to building management system integration.

FAQs

What is a Cat A refurbishment?

1

A Cat A refurbishment returns an office or commercial space to a blank canvas suitable for a new occupier to fit out. It typically includes:

  • A raised access floor

  • Suspended ceiling with recessed lighting

  • Heating, ventilation and air conditioning (HVAC) 

  • Perimeter trunking for power and data

  • Toilet facilities 

  • A basic kitchen or tea point

  • Decoration to a neutral standard 

  • Compliance with all Building Regulations and fire safety requirements

The space is left ready for an incoming tenant to install their own partitioning, finishes and specific fit-out to create their working environment. Cat A specifications can vary, and our team works with building owners and agents to deliver specifications that position the space competitively for the target tenant market.


Do you work with managing agents and building owners?

2

Yes, a significant proportion of our commercial refurbishment work comes through managing agents and building owners who instruct us to deliver refurbishments in their managed portfolios. We understand the commercial priorities that drive these projects – maintaining or enhancing rental values, minimising void periods, delivering work on time and within budget – and we structure our service accordingly.

We provide clear reporting to managing agents on progress and costs, work around the constraints of managed buildings and coordinate effectively with existing building management systems and processes. Many agents and owners return to us for multiple projects across their portfolios, reflecting the quality of our work and the professionalism of our service.


Can you refurbish a commercial property while the building remains occupied?

3

Yes, we regularly undertake commercial refurbishments in occupied buildings, working around ongoing business operations in other areas. This requires careful coordination:

  • Phasing works to keep occupied areas operational

  • Undertaking noisy or disruptive works outside business hours

  • Maintaining fire compartmentation and means of escape throughout the works

  • Coordinating with building management on access and services isolation

  • Communicating regularly with building occupiers about upcoming works

Our project managers have extensive experience in occupied commercial refurbishments and develop detailed programmes and logistics plans that enable works to proceed safely and efficiently while minimising disruption to building operations. In some cases, relocating occupants will be necessary, but this can be achieved with minimal disruption.
