A layout can look fine on paper, but then walls shift, the light changes, and the wrong call gets expensive fast. An interior design contract gives the client a written path through the decisions, so the work stays guided without anyone feeling pushed into signing off too soon.
The contract moves from what gets delivered to how changes get handled, with plain language around staged billing, pausing work if invoices go overdue, and what happens when a builder needs a critical dimension checked on site. The page reads like a sequence of sensible checkpoints, with Raleway headings over Roboto body text and a terrace-green palette with a plum accent, so each section feels like the next clear decision rather than a sales pitch.
- What gets decided early The wording puts the deliverables, revision rounds, and builder coordination in front of the payment details, so the client knows what they’re approving before they see the admin.
- Change control that stays practical The changes section defines “one joined-up set of comments” and covers both client-led direction shifts and builder-led changes that affect drawings.
- Clear handover on termination The ending section explains what happens to issued drawings and schedules if the work stops, without promising unfinished working files.
Measured survey agreement The opening agreement frames the measured survey and layout planning work and keeps questions upfront so surprises don’t land on site. What you get The deliverables list covers the drawings and schedules issued, plus optional coordination with an existing builder. Payment The payment section explains staged invoicing, due dates, and when work pauses and deliverables get held back. Changes The change process defines revision rounds and how extra time gets priced and agreed before work continues. If we need to stop The ending terms explain how either side can end the project and what gets invoiced and handed over, with a Signature for acceptance.
We went from spending hours on every proposal to creating fully customized ones in under 5 minutes. That's not an exaggeration - we timed it.

The contract in full
Measured survey and layout planning services agreement
If anything is unclear, we would rather talk it through early than let it turn into a surprise on site.
What you get
We will deliver the measured survey and layout planning package for your home, based on site measurements and the decisions we agree during the process. Deliverables included: Measured survey notes; Existing plan (as measured); Layout options plan set; Kitchen spec and schedule; Alcove joinery detail drawings; Lighting and switches plan. We will also coordinate directly with your builder if you want us to, using your existing team and their preferred ways of working. Anything not listed above, like additional rooms, extra joinery items, planning applications, or ongoing site inspections, can be added as a separate piece of work if you ask us to.
Payment
We take on this work as a project and we bill in stages, as set out on the proposal. We will invoice at each stage, and payment is due by the date on the invoice so we can book survey time, schedule drawing work, and keep your builder’s programme moving. If you would like us to start earlier than planned, we can usually do that once the first invoice is paid and we have confirmed the survey date. If an invoice goes overdue, we will pause work and hold back any deliverables that are not yet issued until the account is up to date. We will always tell you before a pause causes knock-on delays.
Changes
We include a set number of revision rounds in the proposal. A revision round means you give us one joined-up set of comments on the drawings we have issued, then we update them and reissue. It works best when you agree your feedback between you first, so we are not trying to solve two different briefs at once. If you ask for changes beyond the included rounds, or you change direction after you have signed off a layout or specification, we will price the extra time and agree it with you in writing before we do it. Builder-led changes on site are handled the same way if they affect our drawings.
Who owns what
Once you have paid in full, you can use the final drawings and schedules we issue for this project to price, build, and maintain your home. That includes sharing them with your builder, kitchen supplier, and other trades working on the job. Our working files, templates, libraries, and drawing standards stay ours, even if you have paid for the project, because they are part of how we work across many jobs. If you want to reuse our drawings for a different property, a later phase, or for marketing by a third party, ask us first so we can confirm what is sensible and what needs updating.
Sharing the work
We may photograph or show the finished design work as part of our portfolio, for example on our website, social media, or in a credentials document, because it helps future clients understand what we do. We will not share your address, your full names, or anything we know is sensitive. If you would rather we do not post your project, or you want a delay until after you have moved in, tell us in writing and we will follow that. If your builder or suppliers ask to use our drawings or images for their own promotion, they should come to us for permission first.
Our responsibility
We are responsible for the professional care we bring to the measured survey, the drawings, and the specifications we produce, based on the information available at the time. We are not responsible for the builder’s workmanship, site safety, programme, or the performance of products supplied and installed by others, even when we have specified them. Measurements can be affected by concealed structure and site conditions, so any critical dimensions should be checked by the contractor on site before ordering or cutting. If something looks wrong on site, tell us straight away. We can usually resolve issues quickly when they are caught early, before anything is made or installed.
If we need to stop
Either of us can end the project if it is not working, or if circumstances change. You can do that by telling us in writing, and we will stop work on the date agreed. We will invoice for the work completed up to that point, including any committed time like booked survey and drawing time. If you have paid ahead, we will credit any unused portion against what has been delivered. Once the account is up to date, we will hand over the latest issued drawings and schedules we have completed for this project. We cannot hand over unfinished working files, but we will make sure you have what you need to pick up with a builder or another designer.

Questions about this contract template
Do I need a contract for interior design services?

How do interior designers handle revisions and changes?

Who owns the drawings after an interior design project?
The ownership terms say that once the client has paid in full, the client can use the final issued drawings and schedules for the project to price, build, and maintain the home, including sharing with trades. The designer’s working files, templates, libraries, and drawing standards stay with the designer.
What happens if an interior design project gets paused or ends early?
The payment terms say overdue invoices can pause work and hold back unissued deliverables, with notice before knock-on delays. The termination terms explain invoicing up to the stop date, crediting any unused prepaid portion, and handing over the latest issued drawings and schedules once the account is up to date.
