Residential Building Contractors in Morningside
High-quality extensions, attic conversions and whole-home renovations for homeowners in Morningside and across Edinburgh.
Working in Morningside
Morningside is one of south Edinburgh's most established residential areas, and many homeowners here are planning the kind of substantial project MJM specialises in — opening up a villa to its garden, converting a generous roof space, or bringing a period house fully up to date.
We manage these projects as one coordinated build, from structural work and roofing through to services and final finishes.
Homes & Projects in Morningside
Much of Morningside's housing is stone-built Victorian and Edwardian — detached and semi-detached villas, terraced houses and traditional tenements. These homes often have generous ceiling heights, original cornicing and joinery, and gardens that are poorly connected to the house. Projects commonly involve reconfiguring the ground floor, replacing tired rear additions and carefully repairing original features.
Access can be tight on terraced streets and between villas, so deliveries, skips and scaffolding need planning from the outset.
House Extensions in Morningside
Rear and kitchen extensions are a natural fit for Morningside's villas and terraced houses, typically replacing a small kitchen or outshot with an open-plan space that connects to the garden. Larger projects may combine a single-storey extension with reconfiguration of the existing ground floor.
Attic Conversions in Morningside
Many Morningside houses have substantial pitched roofs that can accommodate a principal bedroom suite, guest room or study. Rooflights, dormers, the new stair, insulation and fire safety all need to be designed together, particularly where dormers are visible from the street.
Home Renovations in Morningside
Whole-home renovations here are often about modernising services — rewiring, heating and plumbing — while retaining the character that makes these homes valuable. We coordinate structural alterations, roofing, plastering, flooring and joinery as part of one programme.
Planning & design considerations
Much of Morningside lies within a conservation area, which influences materials, the visibility of extensions and dormers, and works to trees. Early input from your architect and the council helps shape a design that will be approved.

Questions
Questions about building in Morningside
Do you carry out house extensions in Morningside?
Yes. We build substantial rear, kitchen and side extensions across Morningside, usually alongside reconfiguration of the existing ground floor so old and new spaces work together.
Do you work on period properties in Morningside?
Yes. Many of the homes we see in Morningside are Victorian or Edwardian. We aim to retain and repair original features such as cornicing, shutters and joinery wherever possible.
Can MJM manage an extension and renovation together?
Yes — and in older Morningside homes it often makes sense, because services, layout and finishes can be planned once for the whole house.
Can you work with our architect?
Absolutely. We regularly work from architects' drawings and are happy to review designs early for buildability and cost.
