The short answer
To start, an architect needs a clear sense of three things: your brief (what you want and why), your budget (a realistic figure for the build and fees), and information about the property. Practically, that means your deeds or a site plan, any existing drawings or surveys of the building, the address and access details, and any documents you already hold such as a previous planning decision or a leasehold restriction. They will also want to know your timescale, your priorities (must-haves versus nice-to-haves), and any known constraints — whether the property is listed, in a conservation area, or has obvious boundary or drainage issues. The more accurate the information you provide up front, the faster the architect can produce an accurate brief, fee proposal and design — and the fewer costly assumptions creep in later.
An architect can start a conversation with very little, but to start designing well they need a few specific things. Gathering them before the first meeting saves weeks and sharpens the design.
What to have ready
- BriefWhat you want and why
- BudgetA realistic build + fee figure
- Property docsDeeds, site plan, existing drawings
- ConstraintsListed, conservation, boundaries
- TimescaleWhen you hope to start
Your brief and budget
The two most important things an architect needs are not documents — they are clarity on what you want and what you can spend:
- A clear brief: describe how you use your home now, what does not work, and what you want to achieve. Separate the essentials (an extra bedroom, a bigger kitchen, more light) from the wish-list extras. Photos of styles and spaces you admire help enormously.
- A realistic budget: the architect needs to know the figure you have available for the building work, fees, and a contingency for surprises. Being honest early lets them design something you can actually build rather than a scheme you have to cut back later.
- Your priorities and timescale: what matters most if compromises are needed, and when you hope to start and finish.
A good architect would far rather know your true budget ceiling than guess at it. Withholding the real figure usually leads to a design that has to be value-engineered down, wasting design time.
Information about the property
Alongside the brief, the architect needs to understand the building and site. Useful documents and details include:
| Item | Why it helps | Where to find it |
|---|---|---|
| Property deeds / title plan | Confirms boundaries and ownership | HM Land Registry / your solicitor |
| Existing drawings or survey | Saves remeasuring, speeds design | Previous owner, estate agent, files |
| Site/location plan | Needed for planning later | Land Registry / OS-based map |
| Previous planning decisions | Shows what was allowed or refused | Council planning portal |
| Lease / restrictive covenants | Flags legal limits on work | Your solicitor / deeds |
| Service + drainage info | Affects where you can build | Water authority / survey |

Access, constraints and the practical details
Beyond the brief and documents, a few practical things help the architect get moving and avoid surprises:
- Access for a survey: the architect (or a surveyor) will need to measure the property. Knowing who holds keys and when access is possible lets the survey be booked early — often the first real bottleneck.
- Known constraints: tell them if the property is listed, in a conservation area, near protected trees, or has had previous planning refusals. These shape what is realistic and what documentation will be needed.
- Neighbour and boundary issues: shared walls, rights of way, or boundary disputes that might trigger the Party Wall etc. Act 1996 or affect the design.
- Who else is involved: whether you have already engaged a structural engineer, builder or planning consultant, so the architect can coordinate.
You will not have all of this on day one, and that is fine — the architect can help you source surveys and documents. But the more you bring to the first meeting, the more accurate their feasibility advice and fee proposal will be, and the sooner real design work can start. If you are missing the existing drawings, the measured survey is usually the first paid task, because every later drawing depends on it.
Frequently asked questions
Do I need existing drawings before contacting an architect?
No. If you have existing drawings or a survey they save time, but if not, the architect arranges a measured survey of the property — usually the first task, since every later drawing depends on accurate dimensions. You can start the conversation with just a brief and a budget.
Why does the architect need to know my budget so early?
Because the budget determines what is realistic to design. Knowing the figure up front lets the architect produce a scheme you can actually build, rather than designing something that later has to be cut back, which wastes design time and money.
What property documents are useful to gather?
Your deeds or title plan, any existing drawings or survey, a site or location plan, any previous planning decisions, and any lease or covenant that restricts the work. Not all are needed at the first meeting, but they sharpen the architect's early advice.
