Renovating and extending homes in Midlothian
Midlothian's housing ranges from Victorian villas in towns like Dalkeith and Lasswade to twentieth-century and modern family housing further towards Penicuik and Gorebridge.
For homeowners looking to make better use of an existing property, Allied can undertake extensions, loft and garage conversions, internal reconfiguration, kitchens and bathrooms, alongside more substantial renovation work, though some Midlothian towns do have their own older, more traditional building stock worth treating carefully.

What we cover
Our structural specialism
Complex structural alterations within listed and period properties are where we add the most value. Steelwork, layout changes, cellar conversions and serious structural problems, resolved while preserving the cornices, fireplaces, shutters and staircases around them. It's the core of what Allied does.
Renovation & BuildingThe rooms that get used every day
Kitchens and bathrooms built to sit comfortably inside a period floor plan, finished to a standard that holds up to daily use.
Kitchens & BathroomsDetail work, done properly
Bespoke joinery, staircases and finishes. The details that separate a renovation from a genuine restoration.

Our approach
Our structural specialism.
Listed buildings and period properties come with real constraints, from listed building consent to load-bearing changes and matching original detail exactly. We've built our reputation on exactly that work.
Our core team manages every project directly, supported where required by a trusted network of specialist trade partners whom we know and personally approve.
Locations served
We cover Midlothian including Dalkeith, Bonnyrigg, Lasswade, Loanhead, Penicuik, Gorebridge, Newtongrange and Roslin.
