House Extensions Designed Around the Whole Home

More space should improve the whole home

Rear, side, wraparound and multi-storey extensions

A successful extension does more than add floor area. Mendit delivers rear, side, wraparound and multi-storey additions as part of the home rather than as a separate box attached to it.

Kitchen-living transformations and garden connection

The design should repair awkward circulation, improve natural light, make the garden easier to use and give retained rooms a clearer purpose. Kitchen, dining, utility and storage needs are considered before the footprint is fixed.

Test the opportunity before committing to a scheme

Plot, orientation, drainage, access and neighbouring context

Site levels, daylight, drainage routes, access and the relationship with neighbours shape feasibility. Surveys and measured information allow different forms of extension to be compared on practical terms.

Planning, permitted development and buildability

The appropriate approval route is confirmed for the individual property. Structural strategy, temporary support, material access and weather-sensitive work are considered while the design can still respond.

Resolve the junction between existing and new work

Structure, insulation, glazing and roof junctions

Extensions concentrate risk where new work meets old. Roof abutments, structural bearings, insulation continuity and glazing interfaces are coordinated before they disappear behind finished work.

Levels, thresholds, drainage and external works

Finished floor levels, door thresholds, surface water and the garden connection are resolved as one detail. This avoids a successful interior ending at an awkward or vulnerable external junction.

Coordinate the extension around the finished interior

Kitchen, lighting, joinery and services setting-out

Kitchen manufacturing information, lighting, heating, ventilation and bespoke joinery are brought forward before first fix. Each specialist works from coordinated dimensions rather than assumptions.

Protecting quality through the final sequence

Stone, cabinetry, glazing and decorated surfaces are protected while dependent trades complete. Testing, adjustments and handover records are treated as part of the project rather than an afterthought.

Dorset extensions delivered as one resolved project

Mendit works with homeowners and appointed designers across Dorset, coordinating the route from early feasibility through construction and final finish. Explore house extensions in Sandbanks, extensions in Canford Cliffs, or selected projects.
