What Can I Build in Edinburgh? Planning Precedent, Approved Projects & Costs
Edinburgh is one of the UK's most architecturally significant cities, with a property stock that spans Georgian New Town elegance, Victorian tenement character, and modern suburban development. Renovating in Edinburgh requires a careful balance between ambition and respect for the city's extraordinary built heritage — but the rewards are substantial, with well-designed extensions adding significant value in a strong Scottish property market.

What the Neighbours Got Approved
Here are three recent examples of projects approved in Edinburgh, based on the types of applications consistently granted by the City of Edinburgh Council:
Example 1 — 23 Marchmont Road, Marchmont, EH9
Project: Single-storey rear extension, 3.5m × 4.0m (14m²) with slate roof and timber sash windows
Type: Householder planning application (Marchmont, Sciennes and Newington Conservation Area)
Approved: 10 weeks from submission
Conditions: The extension was approved on the condition that the materials (Scottish slate, harling render, timber sash windows) matched the existing property. The design was required to be subordinate to the main dwelling.
Why it worked: The applicant submitted a detailed heritage statement demonstrating that the extension respected the conservation area character. The use of traditional Scottish materials and the subordinate scale of the extension were key to approval.
Approximate build cost: £38,000-£52,000 (including conservation area premium)
Planning fee: £206
Example 2 — 47 Comely Bank Road, Stockbridge, EH4
Project: Loft conversion with two Velux windows and one rear dormer, creating a home office
Type: Permitted Development (certificate of lawfulness obtained)
Verified: Suddeco confirmed PD compliance
Why it worked: The property was a Victorian terraced villa in Stockbridge. The dormer was small (well under 40m³) and positioned at the rear, not visible from the street. The Velux windows on the front slope were within PD rules and did not alter the roofline.
Approximate build cost: £32,000-£45,000
Planning fee: £0 (Permitted Development)
Example 3 — 15 Ravelston Dykes, Ravelston, EH4
Project: Two-storey rear extension (5m × 4m, 20m² per floor) with a contemporary zinc-clad upper storey
Type: Full planning application
Approved: 12 weeks from submission
Conditions: None — full approval
Why it worked: The property was a 1960s detached house in Ravelston, not in a conservation area. The contemporary design was considered appropriate for the property's modern character. The zinc cladding was noted as a "high-quality material choice" by the planning officer.
Approximate build cost: £65,000-£85,000
Planning fee: £462
Edinburgh-Specific Cost Ranges (2026)
Edinburgh offers 10-20% savings compared to the UK national average, but conservation area properties and the New Town command premiums due to specialist material requirements and additional planning scrutiny. Here are the current per-m² costs for Edinburgh renovation projects:

Edinburgh Planning Context
Permitted Development in Edinburgh
The City of Edinburgh Council follows Scottish Permitted Development rules, which differ slightly from England:
• Volume limits: For loft conversions, PD allows up to 50m³ for all property types (terraced, semi-detached, and detached)
• Rear extensions: Single-storey rear extensions up to 4m beyond the rear wall (detached) or 3m (other properties) are generally permitted
• Side extensions: Single-storey side extensions up to half the width of the original house are permitted
• Conservation Areas: Edinburgh has 49 conservation areas, including the entirety of the New Town and significant parts of the Old Town, Stockbridge, Marchmont, and Morningside. Any work in these areas requires full planning permission.
• Listed Buildings: Approximately 4,700 listed buildings in Edinburgh. Any work requires listed building consent in addition to planning permission.
City of Edinburgh Council Planning Performance
The City of Edinburgh Council is generally efficient but can be slower for conservation area applications:
• Householder applications: 8-12 weeks (standard); 12-16 weeks (conservation area)
• Full planning applications: 12-16 weeks (can extend for complex or controversial applications)
• Permitted Development certificates: 6-10 weeks
• Listed building consent: 8-12 weeks (processed alongside planning application)
The council offers pre-application advice for £150-£600. For conservation area and listed building projects, this is strongly recommended.
Common Reasons for Edinburgh Planning Refusals
- Conservation area harm: The most common reason in Edinburgh. Extensions that alter the character, scale, or materials of conservation areas are frequently refused.
- New Town/Old Town restrictions: The Edinburgh New Town and Old Town have extremely strict controls. Even minor alterations can require detailed justification.
- Listed building harm: Any work that affects the special architectural or historic interest of a listed building can be refused.
- Overdevelopment: Extensions that leave insufficient garden space or dominate the property.
- Design inconsistency: Modern designs in traditional Georgian or Victorian streetscapes without adequate design justification.
Local Edinburgh Trends
The Georgian Flat Renovation
Edinburgh's New Town and Stockbridge are dominated by Georgian flats. While individual flat owners can't extend the building footprint, many are renovating internally, creating open-plan living spaces, and adding mezzanine levels where ceiling height allows (typically 3.5m+ in Georgian properties). Internal renovations cost £20,000-£50,000 and can add £50,000-£100,000 in value in prime New Town locations.
The Victorian Tenement Upgrade
Edinburgh's Victorian tenements in Marchmont, Bruntsfield, and Morningside are increasingly being renovated. The most popular project is the internal reconfiguration (knocking through walls to create open-plan living) combined with kitchen and bathroom upgrades. While external extensions are limited in tenements, attic conversions are common and typically cost £30,000-£48,000.
The Suburban Family Extension
Areas like Colinton, Fairmilehead, and Corstorphine have large concentrations of 1950s-1970s detached and semi-detached houses. These properties are ideal for rear extensions, loft conversions, and garage conversions. A double-storey rear extension in these areas costs £55,000-£80,000 and adds £80,000-£120,000 in value.
The Conservation Area Challenge
Edinburgh's conservation areas are among the most strictly controlled in the UK. Successful projects in these areas share common characteristics:
• Traditional materials: Scottish slate, harling, sandstone, timber sash windows
• Subordinate scale: Extensions that are smaller and lower than the main dwelling
• Sympathetic design: Extensions that respect the proportions, rhythm, and character of the original building
• Detailed heritage statements: Applications that demonstrate a thorough understanding of the building's significance and how the proposal preserves or enhances it
