The Challenge
The clients had purchased a substantial 1920s detached property and required a comprehensive transformation, taking the property back to bare structure and delivering a completely remodelled interior to a luxury residential standard. The project included opening up the ground floor, installing four new bathrooms, a bespoke kitchen, and a full M&E upgrade including underfloor heating, new wiring, and smart home integration throughout.
The Solution
Crown Building appointed a dedicated project manager and contracts manager, and worked to a precise programme that allowed the clients to move in on the agreed date, not a day late. Structural modifications were completed first, followed by a full M&E first fix, then a carefully sequenced finishing programme coordinated with the interior designer. Every trade was Crown Building's own vetted supply chain; no labour only sub contracting. The result is a home that looks and feels brand new, without a single detail compromised.
Scope of Works
“Our house is unrecognisable, in the best possible way. Crown Building handled every single detail and kept us informed every step of the way. We moved in on the day they said we would, and the quality is everything we hoped for.”

Context
Stripping a substantial interwar property to bare structure is the only honest way to deliver a comprehensive remodel, and it is also the point at which the property tells you what it has been hiding. Original wiring, redundant pipework, lath and plaster in variable condition, timber that has moved, and in many houses of this age little or no insulation in the walls and roof.
This is why we prefer to establish scope after strip out wherever the programme allows, and why a contractor who prices a private residence remodel without allowances for what strip out will reveal is either optimistic or intending to recover it through variations. Clarity about that boundary at tender stage is worth more to a client than a headline figure.
Bringing a house of this period up to a contemporary standard also means addressing fabric performance, insulation, airtightness and glazing. Alongside the visible works, because a beautifully finished interior that is expensive to heat is an incomplete job.
Delivery
Multiple new bathrooms in an existing house is principally a drainage exercise. Falls must be achievable within the available floor build up, soil connections have to reach existing stacks, and every wet area needs a tanking system installed and tested before tiling. Where the layout requires drainage that the structure cannot accommodate, that is a design decision to take early, not a discovery to make during second fix.
Underfloor heating and smart home integration then compete for the same programme window. Underfloor heating dictates floor build up and therefore every threshold, door height and stair junction in the house. Smart infrastructure dictates cable routes that must be installed before walls close. Both have to be resolved at first fix, when neither system is visible and neither client decision feels urgent, which is exactly why they need to be forced early.
