Two-storey extension plans and drawings in Glasgow and Dunbartonshire

What a set of extension plans involves

This service suits you if you want clear, accurate plans for a two-storey extension, whether to apply for planning, check permitted development or get build prices. You get a measured survey, sketch options with guide costs, a chosen design developed into planning drawings and, if you go ahead, building warrant drawings coordinated with the structural engineer. Because we also build, the drawings are prepared with the build in mind.

Fees

Planning drawings (survey and design) are a guide of £2,000–£3,500 and building warrant drawings and specification £1,500–£4,000, with your design stage priced in writing before it starts.

Rules in Scotland

In Scotland, the plans support a householder application, costing £371, and later a building warrant application with technical drawings to the Scottish Building Standards Technical Handbooks. Because Class 1B needs 10 m to every boundary, the site plan showing boundary distances is often what decides the route.

There is no Party Wall Act in Scotland. Shared walls and boundaries are governed by title deeds and common law, so we speak to neighbours early and record the condition of shared structures.

Getting the design right

Planning drawings versus building warrant drawings

Planning drawings show what the extension looks like and how it affects neighbours. Building warrant drawings show how it is built: foundations, structure, insulation, fire safety, ventilation and drainage. Most two-storey extensions need both, prepared at different stages.

Compare options early

Sketching two or three layouts, such as rear, side or part two-storey, is the cheapest point to make big decisions. Each option comes with a guide cost and a view on the approval route, so you choose with the full picture rather than discovering limits later.
