Planning a loft conversion in London? Start with accurate existing plans. We create survey-based drawings that help homeowners, architects, and builders move forward with confidence.
Delivered in PDF + CAD (DWG) formats, ready for planning submissions and design work.
A loft conversion transforms unused roof space into liveable rooms—bedrooms, offices, ensuites, or storage. In London, loft conversions are particularly valuable because many homes are Victorian terraces, Edwardian semis, and compact townhouses where extending outward is difficult or impossible.
Good drawings reduce surprises during construction, support planning applications when required, and help meet building regulations. You’ll typically need a measured survey, existing drawings, and often planning or building regs drawings depending on your project scope.
London context: Party walls, conservation areas (Camden, Islington, Hackney), varied roof structures, and past alterations mean accurate measurements are essential before any design work begins.
We focus on the architectural survey and drawing side of loft conversions—giving you (or your designer) accurate information to plan and build with confidence.
Depending on your project needs, we can also provide:
Loft conversion plans
Loft conversion architectural drawings
Loft conversion permitted development drawings
As built drawings for loft conversion
London projects move quickly, and small errors in drawings can become expensive later. We keep it simple: accurate surveys, clear communication, and reliable delivery.
Clear scope, clear pricing, no hidden surprises
Drawings supplied in PDF + CAD for easy next steps
We start from real measurements, not assumptions
Accurate drawings delivered on time, every time
In 6 Easy Steps
We start with receiving your project with brief discussion and understanding requirements.
If you don't have any survey drafts, we have to conduct a site survey and prepare the drawings.
After completing the draft design, we will show it to you for further changes if needed.
If any changes/amendments needed, we will prepare 2-3 changes for free. For the 4th change charges are applicable.
After the changes/amendments, we will then show you the final drafts and submit the invoice for the CAD files and PDFs.
After confirming the final payment. We will then submit you the DWG file as well as the PDFs. We are happy to work with you again soon.
We work across London & Greater London, plus regular commuter-belt areas where extensions are common.

Cost depends on property size, loft access, and scope (existing only vs existing + proposed). A typical terraced house costs £450-£700. We price after reviewing your postcode, property type, and timeline. Pricing is transparent with deliverables confirmed upfront—no hidden fees.
In most cases, yes. A measured survey provides accurate existing conditions, reducing design errors and supporting planning submissions. It’s especially important for London terraces and older homes where walls, rooflines, and past alterations aren’t always consistent with original plans.
Planning drawings focus on external changes and how the proposal fits local policy—what councils review. Building regulations drawings cover technical compliance: structure, fire safety, insulation, and stairs. Your project may need one or both depending on permitted development status.
Yes. We deliver in both PDF and editable CAD formats (DWG). Your architect or designer can work directly from clean, layered files without redrawing from scratch. Standard layer naming conventions are used for seamless integration into design workflows.
Most projects are delivered within 3-5 working days after the site visit. Turnaround depends on property complexity and current workload. If you have a planning deadline or builder start date, mention it early—we can often prioritise urgent jobs.
We produce drawing sets for permitted development routes based on accurate survey data. Whether PD applies is a planning decision, but correct drawings help your architect or consultant assess eligibility and submit confidently if criteria are met.
We survey Victorian terraces, Edwardian semis, 1930s bay-fronted houses, mansion blocks, and townhouses across all London boroughs. Each property type has specific considerations—party walls, conservation areas, roof structures—that we understand from experience.
We provide as-built surveys for completed projects. This captures what was actually constructed for records, lease packs, or future renovation planning. Drawings are delivered in PDF and CAD formats matching the same professional standards as pre-construction surveys.
