We design and deliver the adaptation of existing offices for a new occupier or a different way of working. Layout changes, building services, finishes and furniture form one coordinated scope — from assessing premises before a lease to handing over the completed office.
Office adaptation prepares existing premises for a different brief: occupancy, room functions and business operations. Ecoffices coordinates design and construction together, from defining the alterations to commissioning the building services within the agreed scope.
The starting point is the office your organisation needs, rather than the layout left by the previous tenant. We plan workstations, meeting rooms, private offices, reception and support areas. We then establish how existing infrastructure can be used and where new architectural and technical solutions are required.
We can assess premises before the lease is signed, considering layout options, technical constraints and the extent of alterations required.
Relocating a team, bringing departments together and introducing training facilities call for different layouts. Before designing the alterations, we establish how the office will be used, peak attendance and requirements for meetings, confidentiality and visitors.
We distinguish total headcount from the number of people on site at once. We establish assigned and shared desks, departmental adjacencies and the allowance for agreed headcount growth. These inputs determine space and building-services requirements.
The brief defines room capacities, frequency of use and acoustic requirements. For training rooms and divisible spaces, we consider different configurations, audiovisual provision and how the services will operate in each arrangement.
We plan the relationship between reception, meeting rooms and work areas, alongside access to kitchens, storage and IT facilities. We establish the boundary between visitor areas and the internal workplace, including access-control needs.
An existing fit-out can form part of the new design where it meets the functional and technical requirements. For each discipline, we define the retained elements, alterations and new works. We compare complete solutions, including installation, integration and commissioning.
The photograph illustrates an office interior. The descriptions explain adaptation design principles, not the technical condition of the elements pictured.
The proposed room layout, speech privacy, door requirements and connections to ceilings and floors. Performance is assessed for the complete enclosure, including services penetrations.
Zoning, clear height, acoustics and material requirements. The ceiling plan brings together light fittings, air terminals, detectors and access for servicing.
System performance and condition, services routes, connection points and underfloor access. Floor-box locations are checked against the proposed workstations.
Room-by-room occupancy and heat loads, available building capacity, control zones and maintenance access.
Power demand, circuits, protection and lighting requirements for desks, meeting rooms and circulation. Kitchen appliances and specialist equipment are included in the assessment.
The number and specification of data points, server infrastructure, meeting-room equipment and IT-team requirements. We define the boundary between contractor and client supply.
The revised room layout, fire-safety device locations and controls interfaces with the building management system, or BMS.
Occupancy, water and drainage connection locations, ventilation and equipment power. Joinery dimensions and functions are assessed against the design of the entire area.
An element is retained because it works in the proposed office, not simply because it is already on the premises.
Changing a room’s function affects several disciplines at once. The adaptation design coordinates architecture with ventilation, cooling, power, acoustics and safety systems. We resolve these dependencies before the partitions are built.
We assess full-occupancy loads, fresh-air provision and cooling. The design covers acoustic separation, table power, lighting, data and equipment for remote meetings. The new room is also reflected in the fire-safety device layout.
We establish peak occupancy and room configurations. Ventilation, controls, lighting and audiovisual systems are designed for combined and separate use. Acoustic requirements also cover the movable wall and its perimeter connections.
We assess the location against service risers, drainage routes, ventilation and available power. These constraints affect the joinery layout, floor levels and the extent of work beyond the room itself.
Additional occupancy is checked against ventilation and cooling capacity, while new equipment is included in the power-load assessment. The design covers data points, cable routes and IT-facility requirements, including dedicated cooling where needed.
The cost plan includes the consequences of a new room function across all affected disciplines, not just construction of the room itself.
We deliver adaptations with our own detailed construction design. A survey establishes the starting condition, the test fit organises the functions, and architectural and services documentation defines the work. The same team coordinates design decisions and their implementation.
The design identifies strip-out boundaries, new partitions, ceiling and floor layouts, materials, joinery and building-services solutions. It also defines connections to infrastructure retained on the premises. This information forms the basis of the cost plan, procurement and construction sequence.
An earlier brief or concept can serve as an input. We prepare and coordinate the construction documentation within the scope undertaken by Ecoffices.
Office design scopeAn office left by a previous tenant should be compared with premises for a new fit-out before the leasing decision. Both options use the same brief, specification and equipment scope. This creates a meaningful basis for comparing construction costs and timing.
A new interior designed around the building’s handover condition and available base-build infrastructure.
A new brief accommodated within existing premises, retaining selected solutions and altering the remaining areas and services.
Examples of two different spaces: one without a tenant fit-out and one with an existing interior. This is not a before-and-after comparison.
New fit-out We develop the layout within the constraints of the structure, risers and building-services capacity.
Adaptation We assess which existing divisions suit the brief and how much of the layout needs to change.
New fit-out Services are designed for the intended functions using the connection conditions and handover specification.
Adaptation The new office’s requirements are compared with the performance of existing equipment, services and controls.
New fit-out The full construction and equipment scope is included, with a clear division between tenant and landlord works.
Adaptation Alongside new work, the budget includes selective strip-out, relocations, protection and integration of existing and new infrastructure.
New fit-out Premises readiness, documentation, deliveries and service-provider availability for commissioning are material factors.
Adaptation Assessment of the existing condition and the extent of intervention in retained elements and systems are additional factors.
The recommendation follows the organisation’s requirements and the complete scope of work. A high number of existing elements does not, by itself, establish that adaptation will cost less.
Fit-out design and deliveryChanges to the layout and interior specification can prepare the same premises for a different way of working. The photograph illustrates an interior arrangement; each adaptation scope follows the occupier’s needs and the design of the whole office.
An example of an entrance-area arrangement
The design establishes the relationship between the entrance, reception and meeting rooms, the visitor route and the access boundary to work areas. The layout is coordinated with lighting, power, acoustics and furniture. The same approach applies to team areas, training facilities and support space.
Handover covers compliance with the design, the services installation and readiness of agreed equipment. We also inspect work during construction, before ceilings and enclosures are closed. At handover, completed works are distinguished from retained conditions and client-supplied items.
We check the room layout, partitions, doors, ceilings, floors and joinery, together with materials against the specification. Findings and any defects are recorded in the handover documentation.
We verify operation of the services within scope, balancing and controls. Handover includes the appropriate tests and the involvement of providers responsible for the building systems.
We provide as-built information appropriate to the works, test records, instructions and warranty documentation. We agree how defects will be closed out and who will be responsible for ongoing operation.
The team’s move-in date is confirmed with the client, taking account of handover, IT readiness and client-side furniture and equipment deliveries.
These services can overlap. The principal difference is the objective: accommodating a new occupier or function, comprehensively rebuilding an interior, or improving the performance of an operating office.
Adapting existing premises to a new occupier, brief or way of working. The starting point is the required functions and their feasibility within the office.
You are hereComprehensive rebuilding and renewal of an office, covering architecture, services and finishes. The scope can also change the room layout.
Complete office refurbishmentImproving an office’s functional and technical standard: services performance, comfort, acoustics or equipment, often within occupied premises.
Office modernisationThese questions are worth resolving before choosing premises and starting design. They help define the engagement, the information required and the basis for preparing a proposal.
Yes. Using available plans, documentation, the company brief and a site visit, we assess layout options and the alterations required. We identify points to confirm with the landlord: services capacity, handover specification, retained equipment and access to the premises.
No. It can prepare an existing office for a new occupier or for a changed brief within the current organisation, such as bringing departments together, increasing meeting capacity or introducing training facilities. The scope follows the intended use, not simply a change of tenant.
Yes, to the extent needed for the agreed adaptation. We coordinate the layout with ventilation, cooling, power, lighting and the other services within the design scope. The documentation identifies retained, altered and new elements, together with construction requirements.
Initially, a plan, floor area, team and functional brief, photographs and the intended move-in date. Services documentation and building guidelines allow a more precise scope. Preliminary budgets carry explicit assumptions; a binding proposal follows assessment of the premises and development of the agreed scope and design.
We establish timing after defining the extent of alterations and delivery conditions. Design and approvals are distinguished from construction and commissioning. The programme identifies approval dates, orders and release of the premises on which handover depends. Floor area alone cannot reliably determine a number of weeks.
It can be where the layout and infrastructure suit the new company’s needs. The comparison also includes alterations, relocations and integration of retained elements. Options are assessed against the same brief and specification; using existing equipment does not guarantee a particular saving.
The new layout and occupancy require ventilation and cooling loads to be reassessed. Depending on the result, the design may retain or relocate equipment, change controls or introduce new services. Divisible rooms are considered in each operating configuration.
They can form part of the agreed delivery. The design and proposal distinguish fitted joinery, loose furniture, appliances and audiovisual equipment. They also identify retained and client-supplied items and responsibility for installation, configuration and connection.
Phasing depends on separation of work areas, access to support facilities and services independence. Before approving the programme, we agree workstation moves, transport routes, shutdowns and conditions for returning areas to use. We do not plan for staff to work within an active construction area.
We deliver adaptations with our own detailed construction design. Existing concepts, plans or company guidelines can inform the documentation. The design scope is matched to the project while maintaining coordination across architecture, services and construction.
Send the floor plan, team requirements and planned move-in date. We will establish the technical assessment needed and the design and construction scope. The discussion can also start while you are comparing offices before leasing.
