Privacy notice

Last updated 29 September 2026

Parallel Architecture is a trading name of Robbie Thompson Design Ltd (company 10355527, registered office 7 Barossa Place, Bristol BS1 6SU) and James Nicholson Design Ltd (company 13960890, registered office Second Floor, Kirkland House, 11-15 Peterborough Road, Harrow, Middlesex HA1 2AX), both registered in England and Wales. Both companies act as data controllers for personal information handled through this website, and each appointment is made with one of them, named in its fee proposal. This notice explains what we collect, why, and your rights under UK data protection law.

Robbie Thompson Design Ltd is registered with the Information Commissioner's Office under reference ZC231436, which lists Parallel Architecture as one of its trading names. The contact for anything in this notice is [email protected]. The data protection and security pages describe how information is looked after.

Enquiries

This website has no user accounts and no marketing list. When you contact us, you do so by email. We then hold your name, contact details and whatever you tell us about your project, and use them to answer you. The legal basis is our legitimate interest in responding to enquiries.

Fee proposals and appointments

If you ask for a fee proposal, we record the client's name, the site address and what the project involves, and prepare the proposal from them. If an appointment follows, we keep the records the work produces, such as correspondence, drawings and applications. The legal basis is the contract, including the steps you ask us to take before it is made.

Personal information is shared with others only where the project needs it or the law requires it, for example with the consultants and contractors working on the project, and with the council or building control body when an application is made.

Accepting a fee proposal online

A fee proposal can be accepted online through the personal link printed on it. The acceptance page records the proposal reference, the client's name, an email address if you give one, the statements you tick, your drawn signature, the name of the person signing, the date, the time you send it, and the details your browser gives about itself, such as its name and version. These go over an encrypted connection to a small program the practice runs on Google's servers, which files them in the project's folder in Dropbox and emails us to say they have arrived. The legal basis is the contract you are entering into.

Free tools

The tools in the toolkit work in your browser. What you type into them is not sent to us or stored, with one exception. The planning constraints checker sends the postcode you enter to this website's server, which finds the postcode's centre point from postcodes.io, asks the government's planning data platform and the Environment Agency what is recorded at and near that point, and returns the answer to you. Your browser does not contact those services itself, and the postcode is not stored or logged by us. Your browser may keep the answer for up to a day, and Cloudflare may keep the public services' replies for up to a day, so the same postcode can be checked again quickly. Cloudflare's copies hold the public data, not who asked for it.

The project brief builder can open an email to us in your own email program. Nothing reaches us unless you send that email. If a tool gives you a link to its result, your answers are carried in the link after the # sign. Browsers do not send that part of a link to any server, including ours, but anyone you share the link with can read the answers in it.

The checker also shows a map of what it found up to about 110 metres each way from that point. Your browser draws it from outlines this website's server returns with the answer, and the page loads no map tiles or map library from anywhere else.

Cookies and analytics

This site's own code sets no cookies and saves nothing in your browser, and its fonts, images, film and scripts are all served from this website. Cloudflare, which serves the site, adds the following.

• Cloudflare Web Analytics counts page views and measures how quickly pages load. It sets no cookies and saves nothing in the browser, and Cloudflare says it discards the visitor's IP address without storing it.
• The page the directors use to prepare fee proposals sits behind a Cloudflare sign-in, which sets a cookie on their browsers when they sign in.

Who processes information for us

• Cloudflare serves this website and runs the planning constraints checker's server code. Like any host, it processes visitor IP addresses in its logs to serve pages and protect the site. If a page fails to load, Cloudflare asks the browser to send it a short error report so it can find faults in its network.
• Google runs the practice's email, on Google Workspace, and the program that receives fee proposal acceptances.
• Dropbox stores project records and fee proposal files.

Cloudflare, Google and Dropbox are US companies and may process information in the United States. Each transfer is covered by safeguards UK law recognises: the UK Extension to the EU-US Data Privacy Framework where the provider is certified under it, or standard contractual clauses in the provider's terms.

How long we keep information

Enquiry correspondence that does not lead to an appointment is kept for up to two years, then deleted. Project records for appointed work are kept for at least fifteen years, in line with professional indemnity insurance requirements.

Your rights

You can ask for a copy of the personal information we hold about you, and ask us to correct it, or to delete it where the law allows. You can object to our use of it or ask us to restrict it, and where you gave it to us for an appointment you can ask for it in a form you can pass to someone else. To do any of these, email [email protected]. You will have an answer within one month. If you are unhappy with it, you can complain to the Information Commissioner's Office at ico.org.uk.

Changes

If how the site handles personal information changes, this notice will be updated before the change goes live, and any consent the change needs will be in place first. It is reviewed every six months.
