Delivering Offices That Work — For People and Business

Commercial Construction Contractors has delivered a broad mix of commercial office projects, from new builds in city centres to full refurbishments in out-of-town locations. Whether a ground-up scheme or a complex retrofit, we’ve worked with developers, private clients, and tenants to deliver office spaces that perform on every level.

We’re not here to build offices only, but to create sustainable, functional, and genuinely great workplaces. That might mean a rooftop garden, an on-site wellness space, or an open-plan floorplate with natural ventilation — whatever helps bring the space to life and serve the people who use it. In our approach, we get involved early, plan with care, and focus on getting the right outcome for the asset and the people who rely on it. With every commercial project, we maximise value while managing risk tightly. If you’re planning a fit-out, refurbishment, or commercial new build, we’re ready to help shape and deliver the space properly.

Built on Relationships. Delivered by People Who Care.

At Commercial Construction Contractors, successful projects depend on people, the right skills, experience, and mindset. That’s why we invest in our team and work hard to build long-term relationships with our clients based on trust and consistency. We’ve seen repeatedly that when everyone around the table brings knowledge, commitment, and a collaborative approach, projects run smoother and outcomes are better for everyone.

Our focus is simple: put the right people in place, work closely with our clients, and deliver to a standard we’re proud of. That’s how we’ve earned repeat business and become a trusted delivery partner across the sector.

Our Office Construction Services

We work with businesses across the UK to design, build, and adapt office spaces that are practical, welcoming, and built to last. Whether starting from the ground up or refreshing what you already have, we deliver spaces that make sense for the way you work.

New Office Buildings

Starting fresh? We manage every part of the build, from site prep and foundations to internal fit-out. That includes structure, roofing, walls, M&E, and finishing touches. Whether you're building a new headquarters or a modest space for a growing team, we’ll deliver an office that supports your plans.

Office Fit-Outs

If you’ve got a shell unit ready to go, we’ll turn it into a fully functional workspace. We handle the partitions, ceilings, lighting, cabling, air con, and everything you need to get up and running. We tailor the layout and design to suit your team, culture, and day-to-day needs.

Office Refurbishments

A dated office can hold a business back. If your space no longer works for your team, we’ll help you reimagine it. That could mean new layouts, better lighting, improved acoustics, or a cleaner, more modern look — all done with minimal disruption to your operation.

Extensions and Layout Changes

If you’ve outgrown your space but don’t want the relocation cost or hassle, we can help you expand or reconfigure your office space. Whether adding a new meeting suite or opening up floor space, we’ll work with what you’ve got and make the most of it.

Office Refurbishment Contractors

If your office space in London needs an upgrade, whether it’s dated, empty, or simply no longer fit for purpose, we can help. At Commercial Construction Contractors, we specialise in refurbishing commercial offices that are functional and supportive of the people who work in them.

We work with tenants and landlords across the city to reshape offices into comfortable, modern environments built around how teams work today. Whether you're looking to reconfigure a layout, improve energy performance, or completely refresh a tired space, we bring the right skills and experience to deliver it properly.

Before we start, we take the time to understand what your business needs from the space, whether improving staff wellbeing, adapting to hybrid work, or simply making better use of what you’ve got. From there, we build a plan that fits your goals, your budget, and your schedule.

We know how important your workspace is to your business's success. That’s why we focus on minimising disruption, keeping communication clear, and ensuring the project stays on track from start to finish.

If you plan to refurbish an office in London, we’ll offer advice, walk through your options, or provide a no-obligation quote. Let’s talk.

01. Initial Site Visit and Consultation

Initial Site Visit and Consultation

We start by visiting your site to understand your space, needs, and vision. We listen to what you want from your office, whether it’s more meeting rooms, a modern open-plan setup, or better lighting. We also take measurements and check the site condition.

02. Planning and Design

Planning and Design

Once we understand your requirements, we prepare detailed drawings, select materials, and suggest practical layout solutions. We also verify if planning permission is required and assist with the application process.

03. Quotation and Timeline

Quotation and Timeline

We provide you with a clear and itemised quote, with no hidden costs. We also provide a realistic timeline so you know when each phase will be completed. You approve everything before we begin construction.

04. Site Preparation

Site Preparation

We make the site ready for construction. This includes clearing the space, setting up safety measures, and preparing access for our team and materials. When working in an active office, we section off areas and work in phases to minimise disruptions.

05. Construction and Fit-Out

Construction and Fit-Out

This is where the main work begins. Based on your project scope, this stage may include: Building or modifying internal walls, installing floors, ceilings, and lighting, Electrical and plumbing work, HVAC installation, Fire safety systems, Network cabling and sockets, Joinery, partitions, and glass panels

06. Fixtures and Finishing work

Fixtures and Finishing work

We install all final elements like doors, windows, desks, meeting pods, kitchenettes, flooring, paint, and decor. This is where your office space takes shape, reflecting your brand and personal preferences.

07. Testing and Final Checks

Testing and Final Checks

We test everything: lights, plumbing, internet ports, heating, and cooling systems. We conduct a thorough quality check to ensure everything functions properly and meets all relevant building regulations and safety standards

08. Cleaning and Handover

Cleaning and Handover

Once everything is ready, we deep-clean the site and prepare it for handover. We walk you through the completed space, address any final details, and ensure you’re delighted. After that, we hand over the keys and documents. Your new office is now ready for use.

09. Aftercare Support

Aftercare Support

Even after the handover, we’re here if you need us. Our team is just a call away if you have any questions or need minor fixes.
