Extensions & remodelling · Altrincham, Hale & Bowdon
Extension builders, Altrincham.
Tatton Projects delivers substantial residential extensions, structural remodelling and complete property refurbishments across Altrincham, Hale, Bowdon and the surrounding Cheshire area.
Project delivery
Major home extensions and remodelling in Altrincham.
Our approach combines practical construction delivery with programme, procurement and commercial management. We work with clients, architects, engineers, Building Control and specialist subcontractors to turn an agreed scope into a controlled construction project.
Tatton Projects is owner-managed, so the projects we take get proper attention — the person who priced the job is the person managing it on site. Extensions, remodels and whole-house refurbishments are all welcome.
What we do
From drawings to handover.
Built for substantial projects
A major extension involves structure, foundations, drainage, glazing, M&E, kitchens and finishes. We manage the sequence and coordination rather than treating each package as an isolated trade.
From drawings to construction
If you already have an architect and structural information, we can review the package, develop the construction scope and price the works. At an earlier stage, we can coordinate with the professional team to move the project towards site.
Project-specific cost planning
Ground conditions, steelwork, glazing, kitchens, bathrooms, access and specification can materially change cost. We develop the price around the actual project rather than relying on a headline square-metre rate.

Straight answers
Questions we get asked.
As a 2026 guide across Cheshire and Greater Manchester: £2,400–£3,600 per square metre for a single or two-storey extension with structural alterations, tying into the existing house. It often costs more per square metre than a new build, because nothing is square. Whole-house refurbishment runs £1,400–£2,800 per square metre. Rates exclude VAT, professional fees and abnormals — ground conditions, drainage diversions and structural surprises are found by survey, not by a rate.
Yes. If you already have an architect and structural information, we can review the package, develop the construction scope and price the works. At an earlier stage, we can coordinate with the professional team to move the project towards site.
