Quotes for each survey you choose
A measured building survey in Powys produces accurate floor plans, elevations and sections of your home as it stands today, and a topographical survey records the plot: ground levels, boundaries, trees and drains. Architects use them as the basis for designs and planning drawings, and many surveyors do both in one visit.
Building work in Powys
Stone terraces with slate roofs, valley towns and rural properties are typical in Wales. Extensions, loft conversions and outbuilding conversions are common, and sloping or rural plots can bring trees, levels and drainage into play.
Planning applications in Powys are decided by the local planning authority for Powys. Building regulations are checked by the council’s building control service or a registered building control approver, and party wall matters are handled separately between neighbours.

Common projects in Powys that involve measured and topographical surveys
Extensions
Designers work from measured floor plans, elevations and sections of the house as it is today.
Loft conversions
A roof plan and sections help position stairs, dormers and new floors accurately.
Sloping gardens
A topographical survey records levels so foundations, steps and drainage can be designed properly.
New builds and annexes
Plot surveys show boundaries, trees, drains and neighbouring buildings for planning drawings.
Garden rooms
Levels and tree positions help choose where the building goes and which foundations to use.
What measured and topographical surveys cost in Powys
Survey prices depend on what needs recording. These are the main factors surveyors quote on:
Size of the property or plot
More floors, rooms or land take longer to measure and draw
Drawings needed
Floor plans only cost less than plans, elevations, sections and roof plan
Complexity
Older homes with uneven walls, split levels or complex roofs take longer
Outputs
3D models and point clouds usually cost more than 2D drawings
Timescale
Urgent delivery for a planning deadline may cost more
Sending every surveyor the same drawing list is the best way to compare like with like.

Measured and topographical surveys in Powys: common questions
What is the difference between a measured survey and a topographical survey?
A measured survey records the building: rooms, walls, openings and heights. A topographical survey records the land: levels, boundaries, trees and drains. Many projects in Powys use both.
Can my architect use the estate agent floor plan?
Rarely. Marketing floor plans are approximate and usually leave out wall thicknesses, heights and elevations, so designers normally ask for measured drawings.
What drawings will I get?
Typically floor plans, elevations and sections, and a site plan for topographical work, as PDF and CAD files such as DWG.
How long does a measured survey take?
The site visit for a typical house often takes a few hours. Drawing up follows at the office; ask for a delivery date with each quote.
Do I need a survey for a planning application in Powys?
Planning drawings show the building before and after the work, so most designers start from accurate existing drawings. Your architect can confirm what the local planning authority for Powys will need.
Does a topographical survey show my legal boundary?
It shows physical features such as fences and walls. Legal boundaries are defined by title documents.
Can the building and garden be surveyed in one visit?
Yes. Many surveyors carry out a measured survey and a topographical survey together, which is usually more efficient.
How do I get survey quotes in Powys?
Enter your postcode, answer a few questions about the project and choose which surveys you want quotes for. Local surveyors then send you their quotes.
