Choosing the right partner for a residential refurbishment in London is no mean feat. Whether you’re considering a kitchen overhaul, bathroom upgrade, loft conversion, or a full-house renovation, the market teems with options—from traditional builders to design and build companies like NU Projects.
Having spent 12 years coordinating between homeowners, designers, and builders, I understand the pitfalls and red flags that can quickly turn an exciting project into a nightmare. This post dives into the core differences between NU Projects and a normal builder, focusing on pricing clarity, vetting and accountability, payment protection, and warranties—key areas that make or break a refurbishment.
Introducing the Players: NU Projects, Beams, and APT Renovation
Before exploring the key differences, here’s a quick snapshot of three companies that often come up in conversations about London renovations:
- NU Projects: A design and build company in London that offers fixed-price contracts and prides itself on a single accountable team renovation. Their approach combines in-house architects, project managers, and vetted builders working under one roof for clarity and cohesion. Beams: Known for offering in-house interior designers with cutting-edge 3D visualisation tools, Beams adds a strong design focus that helps homeowners “see before they build.” They also oversee vetting and project management. APT Renovation: A more traditional building company with a reputation for solid workmanship but sometimes limited transparency on pricing and payment schedules.
1. Fixed-Price Contracts and Pricing Clarity
NU Projects Design and Build: No Surprises
One of the biggest headaches with traditional builders is the infamous “from” pricing or vague quotations. NU Projects avoids this by offering genuinely fixed-price contracts, with a transparent breakdown of what is included and excluded from day one. This moves you away from sustainable refurbishment London the nightmare of unexpected extras creeping in mid-project.
This clarity comes from early and detailed scoping sessions, often aided by their in-house architects and designers. Because all your decisions happen upfront, NU Projects can commit to a fixed sum without ambiguous “allowances.”
Typical Normal Builder Pricing: Beware the Red Flags
By contrast, many normal builders provide estimates based on a “best guess” or “from” pricing, which is often provisional. This leads to multiple amendment invoices, creating confusion and distrust. Because the builder and customer often work separately from design, there is scope creep or “extras” blamed on the homeowner changing their mind.
For example, while Beams also offers fixed-price contracts, their pricing sometimes can feel design-driven, and you might be tempted to add upgrades as the project evolves.
2. Builder Vetting and Accountability
NU Projects’ Single Accountable Team Renovation
NU Projects operates as a design and build company, meaning all elements—from architects to the trades—are employed or managed in-house or through trusted subcontractors. This reduces the risk of “blame-shifting.” Their vetting process is stringent, and if anything goes wrong, you have one point of accountability.
What happens if the builder disappears mid-job? NU Projects’ model means this risk is far lower because your contract is directly with them, not a loosely connected subcontractor network. The project manager actively oversees progress and quality control.

Normal Builder Approach: Multiple Contractors
Traditional builders often subcontract much of the work without clear vetting processes. You may find yourself juggling multiple contractors or passing messages through a project manager who may not be fully engaged. This can cause delays and finger-pointing if workmanship isn’t up to scratch.
Companies like APT Renovation typically rely on builders with longstanding local relationships but may not provide the Visit the website same level of formal vetting or multi-disciplinary team integration that a design and build company like NU Projects enforces.
3. Payment Protection and Milestone Releases
Secured Milestone Payments with NU Projects
NU Projects implements a payment schedule based on clearly defined milestone releases that are triggered only on homeowner sign-off. This means you retain control over payments, reducing the risk of paying for incomplete or unsatisfactory work.
This approach contrasts with many builders who require large upfront deposits followed by progress payments according to their own schedule, sometimes without the homeowner’s approval of the work quality.
Beams, too, employs a similar milestone payment system, coupled with comprehensive project management to ensure transparency. However, their emphasis often leans more towards the design and visualisation aspect, and less on the construction phase compared to NU Projects.
Risks with Normal Builders’ Payment Terms
Some traditional builders expect sizeable upfront fees without clear contractual conditions for payment releases. This can leave homeowners vulnerable if the builder halts work or fails to deliver on milestones, with limited recourse.
Do watch out for “hand-wavy ‘from’ pricing” with no detailed payment schedule—this is often a red flag indicating poor payment protection.
4. Workmanship Warranties and Post-Handover Cover
Post-Handover Care with NU Projects
Because NU Projects offers a single accountable team, they typically provide workmanship warranties covering the entire refurbishment. If issues arise after handover, you have a reliable point of contact and structured support.
This reduces the stress associated with snagging lists and makes follow-up work straightforward. The warranty terms are clearly laid out in the contract, giving peace of mind.

Normal Builders and Aftercare
With traditional builders, warranties may be patchy or reliant on individual subcontractors who might be difficult to contact once the project finishes. If problems arise, homeowners often find themselves caught between multiple parties, none willing to take responsibility.
APT Renovation offers workmanship guarantees but they may not include the design or architectural side, sometimes leaving gaps if errors relate to planning or design coordination.

If you prioritise clear pricing, a single accountable team, secure milestone payments, and thorough vetting, NU Projects design and build offers distinct advantages over a traditional builder setup. Their integrated approach using in-house architects London and structured payment controls reduces common refurbishment risks, such as scope creep, “builder disappearing mid-job,” and confusion over who is responsible.
That said, companies like Beams provide excellent design support with 3D visualisation tools, helping homeowners visualise their interiors before committing. APT Renovation might appeal to those seeking traditional craftsmanship but with somewhat less payment and contractual clarity.
Whatever route you choose, always scrutinise the contract terms, confirm payment release rules, and look out for red-flag phrases that suggest vague pricing or unclear warranty coverage. Remember, the key to a successful renovation is not just the builder’s skill but how well the whole process is managed—from design through to final handover.
For a practical start, create your checklist now: How many decision points do you have before signing? What happens if the builder disappears mid-job? Can the company clearly explain their payment milestones and warranty terms? Asking these questions upfront will save you hours of heartache down the line.
