House extension

Yes — absolutely. An architect can attend a house viewing with you, and it’s often a smart move if you plan to renovate or extend. While it’s common in the commercial world, it’s still underused by homebuyers — which is a missed opportunity to spot risks early and unlock design potential before you commit.

Alongside a viewing, an impartial, architect-led pre-purchase appraisal — for example, via The Potential House — can provide objective “architectural due diligence” on feasibility, planning risk and budget impact before you make an offer.

Why bring an architect to a viewing?

  • Feasibility fast. Quick read on what’s realistic (e.g. opening up rooms, adding a dormer/side return, re-routing stairs).
  • Planning & regs sense-check. Early view on permitted development vs planning permission, likely constraints (conservation, overlooking, access).
  • Cost & risk context. High-level implications (structure, services, insulation, fire strategy) so you avoid surprises.
  • Negotiation leverage. Evidence for re-pricing if issues will need remediation.

Impartial pre-purchase advice (not design upsell)

Traditional practices may offer early input to win later work. The Potential House is different — no follow-on design commissions — so guidance focuses solely on whether the purchase stacks up.

Use a viewing + short appraisal to decide: proceed, renegotiate, or walk away.

Can an architect design from an estate agent’s plan?

Often, yes. Agent floor plans, photos and mapping (e.g. Street View/OS mapping) are enough for a desktop feasibility review. This can be a quick way to test options and budget impact before arranging an in-person viewing. For any firm conclusions, an on-site visit is recommended.

 

What will an architect actually do during the viewing?

  • Walk the layout to test your brief (light, flow, proportions, storage, access).
  • Spot structural pinch points (load-bearing walls, spine walls, chimney breasts, stairs, head heights).
  • Flag planning constraints (overlooking, massing, heritage) and Building Regs issues (escape routes, insulation, structure, ventilation).
  • Outline indicative cost/complexity bands and phasing (e.g. stabilise → extend → fit-out).

 

Do I need permission from the agent or seller?

It’s courteous (and often required) to let the estate agent know you’re bringing a professional. For vacant or time-limited slots, they may ask for details in advance. If intrusive checks are needed later (lifting carpets, drilling, opening up), that’s a separate appointment with explicit consent.

 

What if I’m not ready for a viewing yet?

You can still commission a desktop impartial pre-purchase appraisal (e.g. via The Potential House) using listing materials, planning history and policy to test feasibility before you invest time in viewings.
