Finding the perfect property often comes with a vision of potential – reimagining spaces, enhancing light and modernising layouts. If that vision includes removing internal walls, it’s essential to understand the structural and planning implications before you proceed – ideally before you commit to buy. Alongside your survey, an impartial, architect-led pre-purchase appraisal – for example, via The Potential House – can sanity-check feasibility, risks and likely costs for the exact house you’re viewing.
This article covers the key checks to judge whether a wall can be removed safely (and what it might take), plus when to involve professionals.
Why impartial pre-purchase advice helps
Architectural due diligence, not design upsell
• Independent view of feasibility (structure, spans, services)
• Early read on planning/building-regs constraints (e.g. fire-protection to escape routes)
• High-level cost and risk items to inform your offer/negotiation
The Potential House is independent (no follow-on design work), so guidance focuses solely on whether the purchase stacks up.
Is the wall load-bearing?
This is the critical first question. Load-bearing walls transfer weight from upper floors/roof down to foundations. Removing one without appropriate reinforcement can compromise stability and safety.
Identifying load-bearing walls isn’t always obvious — some slender partitions can be structural; others can contain services (soil stacks, electrics). Treat any uncertainty as a “seek advice” flag.
What steps should I take if a wall may be load-bearing?
Get a structural assessment
A qualified structural engineer can confirm whether the wall is structural and specify required supports (e.g. steel beams/lintels, padstones, columns). This insight is invaluable during conveyancing or even earlier at second viewing.Sense-check the knock-on effects
Removing a wall often triggers additional works: fire strategy for the escape route, acoustic upgrades, floor strengthening, and service diversions.Use an impartial architectural appraisal (pre-purchase)
A short, fixed-fee review (e.g. via The Potential House) can test layout options, spans, daylight, and code implications so you know if the plan is realistic — or a cost trap — before you commit.
Planning renovation works? Engage an architect as well
A structural engineer confirms safety and feasibility; an architect ensures the final layout works for light, flow and proportion. They’ll also anticipate ripple effects (e.g. where the new steel drops, how to resolve head heights, storage, circulation). For significant alterations, having both on board gives the clearest picture of scope, cost and programme.
What if there are cracks in the walls?
Cracks are not uncommon, particularly in older properties. While many are benign, some may be indicative of structural movement or underlying issues.
As discussed in this article by Design for Me, a surveyor’s report may flag concerns about cracks or movement. This should not automatically deter you from purchasing, but it is important to investigate further.
A structural engineer can assess whether cracking is historical and stable or indicative of ongoing movement. This assessment can influence your renovation plans, the project’s viability, and even the property’s long-term value.
In summary: do the due diligence early
Don’t assume walls can be removed without proper checks — and don’t go it alone.
Before you buy: get an impartial, architect-led pre-purchase appraisal (e.g. The Potential House) and, where needed, a structural engineer’s opinion to confirm feasibility and likely costs for this property.
After you buy: use Design for Me to compare portfolios and appoint the right architect to design, secure approvals and deliver the build.
