Gantt Chart for Coworking Space Buildout and Construction
Coworking space construction is a race between two clocks: the lease clock (rent commencement date ticking from Day 1) and the construction clock (an 8,000 SF buildout that routinely takes 4–8 months even when everything goes right). A Gantt chart that starts at lease signing and maps every dependency — from TI allowance disbursement to custom millwork lead times to acoustic pod delivery — is the tool that determines whether you open before you've burned through your security deposit.
The post-2020 coworking market bifurcated: enterprise flex (IWG/Regus model targeting large corporate accounts with private suites of 10–50 desks) and community coworking (local SMB and freelancer focus with open desks, phone pods, and conference rooms). Both models follow similar construction timelines; the design language and amenity mix differ.
Typical timeline: 4–8 months for tenant improvement of an existing shell; 12–18 months for ground-up.
Phase 1: Lease Negotiation and Pre-Construction (Before Month 1)
The pre-construction phase for a coworking space begins before the lease is signed. Lease terms directly control the construction budget and timeline:
TI allowance negotiation — Tenant improvement allowance for a coworking space in a Class A office building ranges from $50–100/SF for standard base building condition (HVAC to the floor, electrical panels in place, restrooms built out). For raw shell space, allowances may be $0–30/SF. The gap between the TI allowance and the actual buildout cost (typically $80–150/SF for a full coworking buildout) comes out of the operator's capital. Negotiate the allowance hard — every $10/SF matters on a 10,000 SF space.
Rent-free construction period — Negotiate a rent-free period from lease execution through rent commencement. For a 10,000+ SF buildout, a 4–6 month rent-free period is standard; some landlords will grant more for long-term leases (7–10 years). The rent-free period is effectively construction financing — it determines how many months of carrying costs the operator avoids while the space is being built.
ADA compliance responsibility — Verify who is responsible for bringing the accessible path of travel from the building entrance to the leased premises into ADA compliance. Landlord typically owns the common area path; tenant owns the interior. Misunderstanding this leads to surprise costs late in construction.
Landlord approval process — Most commercial leases require landlord approval of construction drawings before work begins. Build 3–4 weeks into the schedule for landlord plan review; show it as a predecessor to construction commencement on the Gantt chart.
Phase 2: Programming and Space Planning (Months 1–2)
Membership density benchmarking — Coworking space programming starts with the revenue model: how many members does the space need to support to achieve breakeven and target margin?
- Open hot desks: 50–80 SF per workstation (at full-occupancy utilization, not peak simultaneous use)
- Dedicated desks: 60–80 SF per assigned desk
- Private offices: 80–120 SF for a 1–2 person office (smaller offices = higher rent per SF, but harder to sell to teams)
- Conference rooms: 1 per 20 members rule of thumb; size range from 4-person to 12-person rooms
- Phone booth pods: 1 per 20–25 open desks; critical for calls without disturbing neighbors
Technology infrastructure planning — The technology plan must be finalized before MEP design:
- WiFi access point density: 1 AP per 400–600 SF in coworking (higher density than standard office due to high device count — assume 2–3 devices per member)
- Cat6A cabling minimum (supports 10Gbps for future-proofing)
- Access control system selection (Kisi, Brivo, or Salto) determines reader type, power requirements (PoE or hardwired), and data runs — rough-in must match the hardware
- Member management platform (Nexudus, Cobot, OfficeRnD) requires integration with access control, meeting room booking, and billing — select before construction to ensure data infrastructure supports the integration
- Network closet location and size (at minimum: 1 IDF per 10,000 SF; MDF centrally located)
Phase 3: Design Development (Months 2–3)
Acoustic design — The single most common failure in coworking buildouts is inadequate acoustic treatment. Members pay for a productive work environment; phone call noise from the open floor carries 60 feet if the acoustic design is wrong. Key specifications:
- Open coworking ceiling: NRC (Noise Reduction Coefficient) 0.80 or higher — fabric-wrapped panels, baffles, or acoustic tile at density sufficient to absorb reflected sound. An open concrete ceiling or glass wall without treatment is an automatic failure
- Sound masking system: installed in the open coworking area at ceiling rough-in, before ceiling tiles go up. AtlasIED, Cambridge Sound (Qt system), and Lencore are the major commercial providers. Sound masking adds 6–8 dB of background noise that masks conversational speech, dramatically reducing distraction. It cannot be effectively added after construction without removing ceiling panels
- Phone booth pods: STC 35 minimum (Framery O achieves STC 33; Framery Q achieves STC 37; Room pods vary). STC 35 means a normal conversation inside is inaudible from 2 feet outside — adequate for calls, not for confidential conversations
- Private offices: STC 38 partition minimum (standard metal stud + single layer drywall each side + insulation achieves STC ~35; double layer drywall on one side or resilient channel achieves STC 38–42)
- Conference rooms: STC 45 or higher (double-stud wall or single-stud with resilient channel + acoustic insulation + mass-loaded vinyl)
Electrical density — Coworking has higher electrical demand than standard office: 8–10 W/SF total connected load (vs. 5–6 W/SF for conventional office), driven by multiple monitors, sit-stand desks with electric motors, task lighting, and phone charging. Plan receptacle density at open desks: 1 duplex outlet per desk position minimum, 2 for dedicated desks.
Phase 4: Permit Drawings and Submissions (Months 3–4)
Standard commercial permit process. Coworking-specific items that reviewers flag:
- Occupancy classification (most coworking spaces are B occupancy — business — but assembly spaces within the coworking may trigger A-2/A-3 review if they exceed 49 persons)
- ADA: accessible route to all public spaces (phone pods, conference rooms, restrooms, coffee bar); counter heights at reception and café (34" max for accessible); compliant accessible parking ratio
- Mechanical: confirm HVAC is sized for B occupancy density (coworking can be 3–5× the density of a conventional office in the same square footage)
Show plan review period (3–6 weeks typical, varies significantly by jurisdiction) as a distinct Gantt bar with a dependency on design completion and a dependency for construction commencement.
Phase 5: Demolition and Rough-In (Months 3–6)
Demolition — For an existing office TI: remove existing partitions, ceilings, flooring, light fixtures. Retain any reusable HVAC distribution if it aligns with the new layout.
Framing — Private offices, conference rooms, phone pod alcoves (if custom-built rather than freestanding pods). Acoustic partitions for conference rooms and private offices must be framed before MEP rough-in.
MEP rough-in — Key parallel tracks:
- HVAC: conference rooms and phone pods need independent zone control (meeting rooms generate high heat loads from occupants + AV equipment; temperature control per zone is a member expectation)
- Sound masking: speaker rough-in in open area ceiling (typically runs perpendicular to occupancy, at 5-foot spacing in a grid pattern — spacing is system-specific)
- Access control: reader rough-in at each controlled door (entry, private offices, conference rooms, bike storage), PoE run from IDF
- Data cabling: horizontal runs from IDF to each desk position and AP location; conduit for flexibility in desk areas
- Electrical: floor boxes in open coworking area (every 6–8 feet in direction perpendicular to desk rows); column power in open areas if floor boxes aren't feasible; dedicated circuits for coffee equipment in café
Phase 6: Finishes (Months 5–7)
Custom millwork — Reception desk, coffee bar, lounge shelving, phone pod alcove millwork. Lead time: 12–16 weeks from design approval. Order at the beginning of Phase 4. Custom millwork is the single most common schedule risk in a coworking buildout — it can't be rushed, and the space can't open without it.
Freestanding phone pods — Framery, Zenbooth, Room, and ROOM pods are delivered as prefabricated units. Lead time: 10–14 weeks from order. Order during Phase 4. Pods require a standard 120V GFCI outlet inside for internal lighting and ventilation fan; rough-in must match pod footprint. Coordinate exact placement with the architect so floor outlets or wall outlets are located correctly.
Flooring — LVT (luxury vinyl tile) for open areas (durability, easy replacement of damaged sections); carpet tile for private offices and conference rooms (acoustic benefit, ease of replacement); polished concrete in café/lounge areas (cost-effective if slab condition permits). Flooring installation is the predecessor for millwork installation and furniture delivery.
Specialty lighting — Coworking lighting serves two different needs: warm, social lighting in café and lounge areas (2700–3000K, CRI 90+), and higher-output task lighting in work areas (3500–4000K). Dimming capability in conference rooms (occupancy sensor + manual dimmer). LED strips under millwork shelving for accent.
Signage and wayfinding — Room number signs, directional wayfinding, privacy film on glass partitions. ADA-compliant tactile signs at conference room and private office doors (required by ADA Standards for Accessible Design 703.4).
Phase 7: Technology Commissioning (Months 6–8)
Access control programming — Kisi, Brivo, or Salto programming: member access levels, time-of-day restrictions, visitor passes, admin overrides. Integrate with member management platform.
WiFi commissioning — Heat map verification (use Ekahau or NetAlly AirCheck to verify signal strength and channel assignment throughout the space). Adjust AP placement if dead zones exist before furniture is in place.
Sound masking commissioning — Frequency tuning of the sound masking system to the ANSI S12.2 Speech Privacy Class A or B target (masking level calibrated to cover conversational speech at normal volume). Commissioning requires an acoustician or the manufacturer's commissioning technician.
AV commissioning — Conference room AV systems (typically: large-format display or laser projector, video conferencing bar (Logitech Rally Bar, Poly Studio, or Neat Board), HDMI/USB-C content sharing). Test each room's AV before furniture delivery.
Phase 8: Furniture and Soft Opening (Month 8)
Furniture delivery and installation is typically 1–2 weeks. Sit-stand desks require cable management installation after delivery. Don't schedule member tours or soft opening until furniture is 100% installed — a partially furnished coworking space is harder to sell than an empty one.
Soft opening — Invite charter members 2–4 weeks before public launch. Soft opening surfaces operational issues (access control bugs, WiFi dead zones, HVAC comfort complaints) before a critical mass of paying members experiences them.

Building the Gantt Chart
A coworking buildout Gantt chart has four main tracks:
- Lease/legal track — TI allowance disbursement schedule, landlord approval milestones, rent commencement date
- Design/permitting track — Programming, MEP design, permit submission, permit issuance
- Construction track — Demo, framing, MEP rough-in, acoustic treatment, finishes, technology commissioning
- Procurement track — Custom millwork, pods, furniture, AV equipment
Use gantt-chart.io to set the lease commencement date as the project anchor, then map backwards from the target member open date to determine the latest acceptable start date for each procurement item. On a 6-month buildout, custom millwork ordered in Week 12 instead of Week 4 pushes the opening by 8 weeks — and 8 weeks of rent on a 10,000 SF space at $30/SF/month is $20,000. Showing this dependency in the Gantt chart before it happens is how operators protect their capital.
