A whole-house renovation is a planned refurbishment of an entire home, typically combining rewiring, heating, plastering, new kitchen and bathroom, flooring and decoration, and sometimes layout changes, carried out in a logical order under one project.
Getting a whole-house renovation right in Penzance starts with understanding the house you already have: its age, how it was built and what has been altered over the years. We survey first, then commit on paper to a price that holds as long as the scope stays the same. Across the South West, guide prices run at £46,000–£122,000 including VAT, and homes in Camborne, Redruth and Falmouth are covered too.

What are homes like around Penzance?
Older Cornish homes are often built of granite or slatey local stone, with slate roofs and sometimes slate-hung walls facing the weather. Cob cottages survive in places, Truro and Falmouth keep Georgian and Victorian streets, and many towns have rendered post-war houses, bungalows and newer estates on their edges.
Cornwall faces Atlantic gales, driving rain and salt-laden air, so render, pointing and window hardware on exposed elevations need a suitably robust specification.
That mix of housing shapes how we approach a whole-house renovation in Penzance: the age and construction of your home affect the materials, the method and, in the end, the price.
Permissions for a whole-house renovation in Penzance
As Penzance is in England, read the following with that system of planning and building control in mind. We check what applies to your house with the council before you receive a quote.
Internal work such as a new kitchen, bathroom, flooring, plastering or decorating does not need planning permission in England, unless the house is listed, when listed building consent may be needed even for internal changes.
Some internal work is covered by Building Regulations: new electrical circuits and work in bathrooms (Part P), new drainage, structural changes, extractor ventilation and any new window. Notifiable work is certified by a registered installer or by building control.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
We look at the job
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for a whole-house renovation so the price reflects your home.
Written quote
After the survey we send a quote for a whole-house renovation that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Dates and permissions
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for a whole-house renovation are in place before the first day on site.
Finish and handover
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.

Common questions
In what order should renovation work be done?
A renovation should follow a set order so finished work is never damaged by later trades. It usually runs from roof and structural repairs, through strip-out, first-fix electrics and plumbing, then plastering, second-fix electrics and plumbing, kitchen and bathroom fitting, flooring and finally decoration. Windows are usually fitted before plastering. We plan the programme around this sequence so each trade follows on smoothly.
How long will a whole-house renovation take?
On a typical home, allow 8–24 weeks on site, depending on scope. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
Do I need planning permission in Penzance?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Penzance is in England, so England's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
Which parts of a renovation need building regulations approval?
Several parts of a renovation fall under building regulations, including rewiring and new circuits, new boilers and heating systems, structural changes such as removing walls, replacement windows and changes to drainage. Some of this is self-certified by suitably registered trades, and some needs building control approval. In Scotland a building warrant may be needed for certain works. We arrange the right approvals and certificates.
What happens if you find damp or rot?
If we find damp or rot during a renovation, we stop that area, show you the problem and explain the likely cause, such as a leaking gutter, bridged damp-proof course or poor ventilation. We then give you a written price to fix the cause and repair the damage before carrying on. Treating the cause matters more than treating the symptom, so we focus on that first.
