CLEARER COSTS. BETTER PLANNING.

House Extension & Conservatory Roof Costs

Planning a home improvement project starts with understanding the likely investment. Urban Edge provides clear guide pricing for house extensions and conservatory roof replacements across Poole, Bournemouth and surrounding Dorset, helping you understand the potential cost before moving forward with a detailed design and quotation.

EVERY PROJECT IS DIFFERENT

The cost of a hup! house extension depends primarily on the size of the new space, wall configuration, glazing, roof design and internal specification. The guide prices below provide an indication of what different-sized hup! extensions may cost, but every project is individually quoted around the property and your requirements.

Unlike simply buying an extension "off the shelf", every project has to work with your existing property, so the final quotation is based on your actual home and the space you want to create.

Small hup! Extension

Approx. 3m × 3m

£20,700 – £27,000+

A compact extension suitable for creating additional dining, kitchen or living space.

Medium hup! Extension

Approx. 4m × 4m

£36,800 – £48,000+

A popular size for open-plan kitchens, dining areas and larger family spaces.

Large hup! Extension

Approx. 4m × 6m

£55,200 – £75,000+

Ideal where you're looking to make a substantial change to the layout and usable space in your home.

REPLACEMENT ROOF COSTS

How Much Does a Conservatory Roof Replacement Cost?

The cost of a conservatory roof replacement in Poole or Bournemouth can vary depending on the size and shape of the existing conservatory, the roof system selected and whether any structural reinforcement or additional finishing work is required.

£6,000 – £20,000+

For modern conservatory roof replacement projects.

Smaller Conservatory Roofs

Simple roof shapes and smaller footprints will generally sit toward the lower end of the price range.

Larger or Hybrid Roofs

Larger structures, more complicated roof designs or combinations of solid panels and glazing typically require a greater investment.

Bespoke Transformations

Structural alterations, premium glazing, rooflights and more extensive internal finishing can move projects toward the upper end of the range.

HOUSE EXTENSION COSTS

What Does a Traditional House Extension Cost?

Urban Edge is based in Poole and provides extension and conservatory roof quotations throughout Poole, Bournemouth, Christchurch and surrounding Dorset. Because properties, access, existing structures and specifications vary considerably, our published prices are intended as a useful starting point rather than a fixed quote for every project.

The cost of a house extension can vary considerably depending on its size, construction method, design, glazing and level of internal finish. Urban Edge offers both modern hup! construction and wider house extension solutions, so we price each project individually rather than applying one standard rate to every property.
