What Information Do We Need to Quote a Modular Building?
Use this modular building quote checklist to prepare the use, size, site, access, services and specification details needed for a clearer project-specific quote.
Short answer
For a modular building quote, KC usually needs the intended use, approximate size or room schedule, site postcode, temporary or permanent requirement, target date, access details, services, drainage, groundworks status, finish expectations and any sketches, drawings or site photos available. You do not need a complete technical pack to start the conversation, but the clearer the brief, the easier it is to recommend the right route, identify project-specific constraints and prepare a more accurate scope for review.
Who this guide is for
This guide is written for UK buyers who are close to requesting a modular building quote but are not sure what information to prepare first.
Facilities managers
Planning offices, staff space, reception buildings or operational accommodation.
School business managers
Preparing classroom, staff support or school-site modular building briefs.
Contractors and site managers
Checking welfare units, site offices, canteens, toilets, changing or drying spaces.
Councils and public sector teams
Preparing a traceable scope for stakeholder review, procurement or budget approval.

Gathering early room schedule, patient-flow, access and service details for review.
Project managers and specifiers
Trying to reduce quote ambiguity before system selection, site review or procurement.
Modular building quote decision table
| Situation | Recommended route / what to check | Why it matters | Next step |
|---|---|---|---|
| You know the building type but not the system. | Send intended use, approximate size, site postcode and target date. | KC can then route the enquiry towards offices, classrooms, welfare, public sector, healthcare-style or bespoke options without forcing the wrong system too early. | Request a quote |
| You are unsure whether the building should be temporary or permanent. | State expected duration, relocation needs, finish expectations and approval status. | Temporary and permanent routes can affect specification, foundations, services, approvals, cost assumptions and future relocation. | Compare temporary and permanent routes |
| Your site may be tight, live, public-facing or difficult to access. | Send site photos, access notes, gate constraints, turning space and overhead obstructions. | Access, cranage, delivery route and working restrictions can change feasibility, programme and installation planning. | Check site access |
| You are planning construction welfare. | Confirm worker numbers, facilities needed, project duration, services and buy or hire preference. | A welfare unit can support part of the site welfare provision, but whole-site suitability depends on the full welfare plan and project conditions. | View welfare units |
| You need a quote pack for internal approval or finance assessment. | Provide scope, use, size, layout intent, service requirements, delivery assumptions and budget direction. | Clear assumptions help a quote pack show what is included, what is excluded and what still needs review. | Review finance and quote pack guidance |
The core information KC needs before quoting
A modular building quote is not just a price for a box. It is a scope built around use, size, specification, site conditions, delivery access, services and project-specific requirements. These are the details to prepare first.
1. Intended use
Explain what the building must do: office, classroom, welfare unit, sanitary block, clinic-style space, showroom, public service building, lodge or bespoke commercial use. A building used for staff workspace has different assumptions from a classroom, welfare unit or public-facing facility.
2. Approximate size or room schedule
A useful starting point can be an approximate footprint, number of rooms, occupancy expectation or simple room list. For example: two offices and a meeting room, one classroom with toilets, or welfare space with canteen, drying room and toilets.
3. Temporary or permanent requirement
State whether the building is expected to serve a short-term project, a longer-term operational need or a permanent expansion. This affects the recommended route, specification, foundations, relocation assumptions and approvals conversation.
4. Site postcode and delivery location
The postcode helps KC understand approximate delivery location, access context and regional considerations. If the project is in Staffordshire, Stoke-on-Trent, the West Midlands or elsewhere in the UK, include local site notes rather than only the head office address.
5. Target date and programme pressure
Share the date you are working towards, but treat it as a planning target until the scope, approvals, site readiness, specification and production route have been reviewed. Avoid assuming a fixed delivery time before the project has been assessed.
6. Site access and cranage restrictions
Access can be one of the biggest differences between a straightforward quote and a complex one. Include notes on gates, road width, turning space, parking restrictions, overhead cables, trees, neighbouring buildings, live-site constraints and crane or lifting space if known.
7. Services, utilities and drainage
List whether power, water, foul drainage, data, heating, cooling, toilets, showers or kitchen facilities are needed. State whether existing services are available nearby, unknown or not yet planned.
8. Groundworks and foundation assumptions
Tell KC whether the groundworks are complete, planned, unknown or part of the required conversation. Foundations, levels, drainage, made ground and client-side enabling works can affect the scope and programme.
9. Finish expectations
Explain whether the building is mainly functional, staff-facing, student-facing, public-facing, branded or premium. External finish, internal fit-out, glazing, flooring, washrooms, acoustic requirements and accessibility expectations can change specification.
10. Drawings, sketches, photos or surveys
Drawings are useful, but not always needed for the first review. A marked-up site photo, rough sketch, room schedule or simple plan can help KC understand the brief before more detailed design work is required.
Why incomplete quote requests are harder to price
| Missing detail | Potential issue | What to send instead |
|---|---|---|
| Use case | The wrong building route or specification may be assumed. | State the building purpose and who will use it. |
| Approximate size | The quote may be too broad to support a budget decision. | Send a room list, footprint, occupancy estimate or sketch. |
| Site postcode | Delivery, access and regional logistics cannot be considered properly. | Send the site postcode and any location notes. |
| Access constraints | Transport, cranage or installation assumptions may be wrong. | Send photos of entrances, roads, turning areas and obstructions. |
| Services and drainage | Toilet, shower, kitchen, welfare or clinic-style requirements may be under-scoped. | List required utilities and whether existing connections are available. |
| Budget direction | KC may not know whether to recommend a functional, standard, premium or bespoke route. | Share a budget range or procurement constraint if one exists. |
Quote checklist by project type
Different modular building projects need different supporting detail. Use the relevant checklist below as a starting point.
Modular office quote checklist
- Number of staff, desks, offices or meeting rooms.
- Client-facing or back-office use.
- Toilets, kitchenette, reception or breakout space.
- Temporary, relocatable or permanent expectation.
- External appearance and branding requirements.
- Access, parking and installation constraints.
Modular classroom quote checklist
- Number of classrooms, pupils or staff spaces.
- Teaching use, support rooms, toilets or specialist spaces.
- Term-time, holiday or phased delivery constraints.
- Safeguarding, access and live-school site constraints.
- Known planning, building control or stakeholder requirements.
- Any layout sketches, site plans or photos.
Welfare unit quote checklist
- Project duration and expected workforce.
- Toilets, washing, canteen, rest, changing or drying needs.
- Static, mobile, buy, hire or future relocation preference.
- Site services, drainage and water availability.
- Live-site constraints, delivery access and working hours.
- Any wider site welfare plan already in place.
Public sector or healthcare-style quote checklist
- Stakeholder, procurement or governance requirements.
- Room schedule, public access and operational continuity needs.
- Accessibility, privacy, fire strategy or service requirements to review.
- Approval route, planning status and building control assumptions.
- Budget stage: early estimate, formal quote or approval pack.
- Any drawings, policies or site constraints already known.
Checks that may affect the scope
Some project checks sit outside a simple building quote. KC can help buyers prepare the right information, but final requirements depend on project review and the relevant approval route.
- Planning and Building Regulations: these are separate considerations. GOV.UK explains that Building Regulations approval is different from planning permission and that a project may need both. Use the GOV.UK Building Regulations approval guidance and the Planning Portal explanation of the difference for official context.
- Construction welfare: if the building is part of a construction site welfare setup, review HSE guidance on toilets, washing, changing, eating and rest facilities. A unit alone does not make the whole site compliant; the wider welfare plan matters. See the HSE construction welfare overview.
- Sector-specific use: schools, public sector, healthcare-style spaces and public-facing buildings can require more detailed checks around accessibility, fire strategy, services, operational continuity and stakeholder approval.
Assumptions and project-specific caveats
Planning, Building Regulations, fire strategy, accessibility, foundations, utilities, drainage, delivery access and services are project-specific. Requirements can depend on intended use, site conditions, duration, size, local planning authority, building control route, specification and access. A bespoke modular route should be quoted from site details, intended use, access, services, layout and finish expectations. KC can help buyers prepare the right project information, but final scope, approvals and suitability depend on project review.
What happens after you send a quote request?
- Initial review: KC reviews the use case, location, size, access, services and target programme.
- Clarification: the team may ask for missing details, photos, sketches, drawings or service information.
- Route recommendation: the project can then be directed towards the most suitable modular route, subject to scope review.
- Quote pack: once enough information is available, the quote can define the assumed scope, specification, exclusions and next actions.
- Next-stage checks: site readiness, approvals, technical details and procurement requirements are confirmed before commitment.
Common mistakes to avoid
Asking only for a square metre price
Cost depends on use, system, specification, site, access, services and fit-out. A square metre figure without context can mislead.
Assuming planning is not needed
Planning and building control requirements are project-specific. Check early rather than treating modular buildings as automatically exempt.
Using the wrong address
Send the site postcode, not only the office or procurement address. Delivery location matters.
Leaving access until later
Gate widths, turning areas, cranes, overhead cables, live sites and working hours can affect delivery and installation assumptions.

Frequently asked questions
Can KC quote without drawings?
KC can usually start an initial review without formal drawings if you can provide the use case, approximate size, site postcode, target date and basic access information. Drawings, sketches and site photos are still helpful because they reduce assumptions. A firm or detailed quote may need more information after the first review, especially where the building has services, toilets, drainage, public access, school use, healthcare-style use or unusual site constraints.
Do I need to know the exact size before requesting a quote?
No. An approximate size, room schedule or occupancy estimate is enough for an early conversation. For example, you might say that you need two classrooms, an office with meeting space, or welfare facilities for a defined workforce. The exact footprint can be developed after the intended use, site constraints, access, services and finish expectations are understood. If you do have a preferred size, include it and explain whether it is fixed or flexible.
Why does the site postcode matter?
The site postcode helps KC understand where the building will be delivered and installed. Delivery location can influence logistics, access review, regional planning context, working restrictions and the practical route to site. It also prevents confusion where the buyer’s office address is different from the project location. Include the postcode for the actual site and add short notes on access, surrounding roads, gates, overhead obstructions and any live-site restrictions.
Should I request a temporary or permanent modular building?
State the expected use period and let KC review the route with you. A temporary building may suit a short-term project, site compound or temporary capacity need. A permanent route may be more suitable for long-term office, classroom, public-facing or operational space. The right answer depends on use, site, access, programme, specification, foundations, services and approvals. Do not assume the cheaper or faster route is the best fit before the brief has been reviewed.
What if I do not know whether planning permission is needed?
Say that the approval route is unknown. Planning permission and Building Regulations approval are different considerations, and requirements can depend on intended use, size, duration, location, local planning authority, building control route and specification. KC can help identify what information should be prepared for review, but final planning or building control advice may need the relevant authority, building control body or professional adviser.
What information helps KC quote faster?
The most useful details are the intended use, approximate size or room schedule, site postcode, temporary or permanent requirement, target date, access constraints, services needed, drainage and groundworks status, finish expectations and any drawings, sketches or photos available. A budget direction is also helpful if you have one. It allows KC to avoid recommending a route that is unsuitable for the project’s scope, procurement position or expectations.
Ready to send your project details?
Send KC your use case, approximate size, site postcode and any access, service or layout notes you already have. KC can then advise what information is needed for a clearer project-specific quote.
