A garage conversion turns an integral or attached garage into a warm, habitable room by insulating the floor, walls and ceiling, replacing the garage door with a wall and window, and adding heating, lighting and finishes.
We offer a garage conversion across Perth and Kinross, and Perth is one of the places we cover, along with nearby Auchterarder, Blairgowrie and Crieff. Before anything is agreed we visit, check the existing structure and talk through your options. You then receive a written quote setting out the full scope; for most homes in Scotland it sits within £11,500–£27,000 including VAT.

What should you budget for a garage conversion in Perth? Use the figures below as a starting point. Prices in Scotland sit about 4% below the national guide, so the range here is £11,500–£27,000 including VAT. Your fixed price comes in writing once we've surveyed the property, at no charge.

What are homes like around Perth?
Perth has Georgian terraces and Victorian sandstone villas, Highland Perthshire towns such as Pitlochry and Aberfeldy have stone villas and cottages, and Kinross and Crieff mix older stone housing with post-war and modern estates. Slate roofs and harled finishes are common in rural areas.
Inland areas get hard frosts and snow on higher ground, and the Tay and its tributaries have a history of flooding.
Whatever era your Perth home dates from, we plan a garage conversion around how it is actually built rather than a one-size-fits-all specification.
Planning and building rules in Perth
Because Perth falls under Scotland's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.
In Scotland, converting an attached or integral garage usually needs no planning permission unless a condition restricts it.
A building warrant is normally needed, because the work changes the use of the space and alters the walls and insulation.
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
A visit to your home
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 garage conversion so the price reflects your home.
Written quote
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Plan and prepare
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
Build and hand over
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.

Questions about a garage conversion in Perth
Can you combine a garage conversion with other work?
Yes. Because we manage several trades under one contract, we can plan a garage conversion alongside other work on your Perth home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
How long does a garage conversion take?
A straightforward integral garage conversion usually takes two to four weeks on site. Attached garages that need roof or wall upgrades, and conversions with a shower room, typically take four to six weeks. Detached garages turned into annexes can take longer. Before work starts, allow time for drawings and building control approval. We give you a clear programme with your written quote.
Does the floor need raising?
Garage floors are usually lower than the house floor and slope towards the door for drainage. Most conversions raise the floor with a damp-proof membrane, insulation and either a screed or a timber floor, so it lines up with the house and removes the step. The final level depends on ceiling height and the door into the house. We measure both during the survey.
How much will a garage conversion cost in Perth?
As a guide, expect to pay £11,500–£27,000 including VAT for a garage conversion in Perth. That range is adjusted for Scotland, which runs about 4% below the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
Can I keep some storage space?
Many people keep part of the garage for storage by building a dividing wall, leaving a smaller store at the front behind the existing door and converting the area behind into a room or utility. This keeps the look of the house unchanged and gives you somewhere for bikes and tools. The converted part still needs the same insulation, ventilation and fire separation.
