House Refurbishment: Where Uncoordinated Trades Cause Delay

A full refurbishment involves structural openings, rewiring, replumbing and finishes all happening in sequence. Without a single coordinated design, trades work from incomplete information, which causes delays and costly on-site decisions.

Common challenges

How ArchEvolve solves them

How an ArchEvolve Project Works

Every project follows a clear, stage-by-stage process aligned with the RIBA Plan of Work framework.

Initial Consultation
We discuss your brief, site and budget for your house refurbishment project, along with any planning constraints specific to your council. Free, no obligation.

Feasibility Assessment
We assess planning viability and site constraints before any design fees are committed. This includes a full survey of existing structure, services and any period features that need to be retained or protected.

A Different Standard of Design for House Refurbishment in Sussex and Surrey

Most practices in the region still work in 2D CAD. ArchEvolve designs house refurbishment projects in Revit and renders in Enscape, so you see the finished space before planning is submitted.
3D Visualisations Included

Every house refurbishment project is modelled in Revit and rendered in Enscape. You see accurate light, materials and spatial quality before a planning application goes in.

Faster Planning Submissions

Drawings produced in a coordinated 3D environment are more complete and less prone to officer queries, which keeps your house refurbishment timeline on track.

Local Planning Knowledge

ArchEvolve has submitted house refurbishment applications across West Sussex, East Sussex and Surrey planning authorities. Your submission is prepared for the specific council from day one.

End-to-End Service

From feasibility through to construction drawings, Alex Page manages every stage of your house refurbishment project personally. No handoffs, no junior staff taking over mid-project.

House Refurbishment Design Across Sussex and Surrey

ArchEvolve designs full house refurbishments for period and modern properties throughout the region, coordinating structure, layout and finishes as one project.

Internal refurbishment work generally does not require planning permission unless it involves external alterations, structural openings affecting a listed building, or changes to the property’s external appearance. ArchEvolve confirms your specific requirements at the free initial consultation.

Yes, for most structural work, rewiring, replumbing and thermal upgrades. The scope of Building Regulations depends on how extensive the refurbishment is, and ArchEvolve prepares the full package as part of the service.

Design fees depend on the scale of the refurbishment and whether structural, mechanical and electrical coordination is required throughout. ArchEvolve agrees a fixed-scope fee in writing before work begins. Our guide to adding value to your home is a useful starting point for planning your budget.

Yes. Many clients refurbish in stages for budget or living arrangement reasons. ArchEvolve designs the whole scheme up front so each phase is coordinated with the next, rather than designing phase by phase and creating conflicts later.

The service covers existing condition survey, whole-house concept design in Revit, planning application where needed, full Building Regulations drawings, and construction drawings for your contractor to price and build from.

Yes. Where a property is listed, this work is handled through our dedicated listed building design service, which addresses Listed Building Consent alongside the refurbishment design.

ArchEvolve covers West Sussex, East Sussex and Surrey, including Worthing, Horsham, Chichester, Crawley, Guildford and Brighton, with a free initial consultation offered throughout the region.
