What's includedServices
Building services across London
Hawk Builders works on the structural end of domestic building — the jobs where the drawings matter, Building Control is involved, and the price needs to be itemised before anyone starts.
Core services
The six areas we work in
Each has its own page setting out exactly what the work covers, so you can see what is included before you ask for a price.
Loft conversions
Dormer, hip-to-gable and mansard conversions that turn roof space into a proper room.
What's included
Renovations & refurbishments
Whole-house refurbishment and internal reconfiguration, managed as one job rather than a dozen trades.
What's included
Kitchens & bathrooms
Full strip-out and installation, including the first-fix plumbing and electrics behind the tiles.
What's included
Structural work & groundworks
Steels, foundations, underpinning and drainage — the work everything else depends on.

Insulated garden offices, studios and outbuildings — built, clad and connected to power.
What's includedAlso undertaken
Other work we take on
These come up less often, so they do not have their own pages — but they are within scope. Ask when you enquire.
New builds
Ground-up residential builds and infill plots, managed from groundworks through to final fit-out.
Commercial fit-outs
Shops, offices and small units taken from shell condition to a space that is ready to open.
Process
The same process on every job
Enquiry
Call, WhatsApp or send the form with your postcode and what you are planning. Drawings or photographs help, but an idea is enough to start.
Site visit
We come and look. Access, existing structure and ground conditions decide more about a build than any drawing does.
Itemised quotation
A written quote broken down by stage and trade, stating the assumptions the price rests on and listing who supplies each item and who fits it.
Construction
Materials and trades sequenced in the right order so the job does not stall waiting on itself. One point of contact throughout.
Completion and handover
A walkthrough of the finished work, certification for the works carried out, and a direct number if anything needs attention afterwards.
