How to buy an architecture practice: valuation, structure and funding

This guide is for architects and design-led businesses thinking about acquiring a practice: a director buying out a retiring founder, a growing studio adding a sector specialism, or a multidisciplinary consultancy bringing architecture in-house. It covers why buyers acquire, how practices are valued, the share-or-assets decision, due diligence specific to architecture and how deals are funded. Smart Funding Solutions is a broker, not a lender, and arranges acquisition funding from £10,000 to £20 million. Our architect practice finance page covers the profession's wider borrowing needs.

01Why buy rather than grow organically

Winning work in a new sector can take years of competitions, bids and relationship building. An acquisition can bring, in one step:

• Sector credentials. A track record in healthcare, education, residential development or heritage work that clients and frameworks ask for.
• People. Experienced architects and technologists, at a time when recruiting them is slow and expensive.
• Client relationships and an order book. Live commissions and repeat clients such as developers, housing associations and public bodies.
• Geography. A studio in a region where your clients want a local presence.

Be careful with framework positions. A place on a public sector framework is usually awarded to a specific legal entity and may not survive a change of ownership or an asset transfer, so check the framework terms before treating it as part of what you are buying.

02Finding a practice to buy

Most architecture practices are small, and many founders have no obvious successor. Opportunities come through professional networks, regional RIBA contacts, accountants and solicitors who act for practices, specialist business brokers and direct approaches to firms whose work you admire. The simplest deals are often internal: a senior associate or director buying out the founder, which is covered in our guides to management buyout finance. Buying into a firm you do not already work for is a management buy-in, and lenders assess the incoming team's experience closely.

03How architecture practices are valued

Turnover is a poor guide, because fee levels and staffing vary enormously. Buyers and their lenders usually start with profit, adjusted to reflect what the business would earn under new ownership:

• Normalised profit. Remove the founder's personal costs and replace their drawings or salary with a market salary for the role they perform.
• Order book quality. Secured fees remaining, by project and RIBA stage, and how many of them are at risk of stalling at planning or funding.
• Repeat clients. The share of fees from clients who have instructed the practice more than once.
• Work in progress. Fees earned but not yet billed, and whether the stage on each job can actually be invoiced.
• Founder dependence. If clients hire the founder rather than the practice, value is at risk the day they leave.

Prices are often set as a multiple of normalised profit, with part linked to future performance. Goodwill is the largest part of the price in most deals; our page on goodwill finance explains how lenders treat it.

04Share purchase or asset purchase

Historic liability is the issue that sets architecture apart. Claims for defective design can surface many years after a building is finished, and changes made by the Building Safety Act extended the time limits for some claims; the government's redress measures information sheet summarises them. On a share purchase you inherit that tail, so warranties, indemnities, a retention from the price and the target's PII history matter a great deal. On an asset purchase, the seller needs run-off PII for past work, and you should confirm it is in place. On either route, staff transferring on an asset deal are protected by the rules on business transfers and TUPE.

Turnover is a poor guide, because fee levels and staffing vary enormously.

05Due diligence specific to architecture

• Registration. Confirm which principals are registered, since "architect" is a protected title, using the ARB Architects Register. A practice that markets itself as architects needs registered people to continue doing so after the deal.
• PII. Current policy, limits, exclusions (fire safety and cladding exclusions are common), notified claims and circumstances, and the renewal outlook.
• Appointments and warranties. Terms of live appointments, collateral warranties given to funders and purchasers, net contribution clauses and any unusually onerous liabilities.
• Higher-risk work. Involvement in residential buildings in scope of the Building Safety Act, and any duty-holder roles taken on.
• Fees and debtors. Unbilled work, disputed fees and clients who pay slowly.
• Software and IP. BIM and CAD licences may not transfer automatically; check ownership of drawings, models and any licensed designs.
• People. Key staff, notice periods, restrictive covenants and how the team is likely to react to a new owner.
• Premises. Lease terms, assignment rights and dilapidations.

06Funding the purchase

Architecture practices have few hard assets, so lenders fund acquisitions on the strength of the combined firm's cash flow, usually with personal guarantees from the buyers. A typical structure layers:

1. Your own contribution. Lenders want the buyer to have money at risk.
2. An acquisition loan. Sized on what the enlarged practice can comfortably repay after salaries, PII and overheads. See acquisition finance.
3. Deferred consideration or an earn-out. Part of the price paid to the seller over time, often linked to fees from transferred clients or profit, which keeps the seller engaged during the handover. Our guide to vendor finance and deferred consideration explains how these rank alongside bank debt.
4. Working capital headroom. Stage billing means cash can dip after completion, especially if WIP is not included in the price; a revolving facility alongside the loan is often sensible.

Illustration: a founder buyout

Illustration only, with round, hypothetical numbers. Two associate directors agree to buy a founder's practice for £600,000. They contribute £60,000 between them, and the founder accepts £180,000 deferred over three years, linked to fees from the practice's existing clients. That leaves £360,000 to raise. A lender will test whether the practice, after paying the associates market salaries and covering PII, generates enough surplus to service that loan with room to spare, and will ask what happens if one large commission stalls at planning. If the answer is uncomfortable, more deferral or a lower price is the realistic fix.

07How long a practice purchase takes

Buying an architecture practice typically takes several months from first conversation to completion, and the stages overlap more than buyers expect.

1. First approach and confidentiality. The seller shares accounts and an overview once you have signed a non-disclosure agreement. Founders are often cautious here, because news of a sale can unsettle staff and clients.
2. Indicative price and early funding view. You form a view of value from normalised profit and the order book, and test with a broker or lender what borrowing the figures might support.
3. Heads of terms. The price, the deferred element, share or asset route, the founder's handover role and a period of exclusivity are agreed in outline.
4. Due diligence and funding application. These run side by side. Financial, legal and PII checks happen while the lender reviews the case and asks its own questions.
5. Legal documents and third-party consents. The sale agreement, deed of priority with the seller and security documents are drafted. On an asset purchase, client novations and lease assignments can take the longest, because each depends on someone outside the deal.
6. Completion and announcement. Funds are released, ownership passes and staff and clients are told, ideally with the founder alongside you.

The most common delays come from incomplete fee and WIP records, PII questions that need the insurer's input, and clients slow to sign novations. Starting the insurer conversation and preparing a clean fee forecast early can save weeks. Our guide to due diligence when buying a business covers the wider checks.

08Common mistakes buyers make

• Paying for an order book without checking which projects have planning and funding.
• Assuming a framework place or key client will transfer automatically.
• Underestimating the PII premium for the enlarged practice.
• Leaving no working capital for the months after completion.
• Failing to agree how the founder will introduce clients and step back.

09What lenders look at in an architecture acquisition

• Maintainable profit: what the combined practice earns after paying the buyers market salaries and covering PII premiums.
• The fee pipeline: how much of next year's income sits in signed appointments, and how much depends on one client or one scheme reaching planning.
• PII history: notified claims, exclusions and whether cover can be renewed on similar terms after the change of ownership.
• The buyers: their registration, track record with the practice's clients and whether the team will stay.
• The seller's deferred payments: how much is owed, when, and whether the seller will agree to rank behind the lender.
• Your contribution: the cash the buyers put in, which shows commitment and cushions the lender.
