Frequently Asked Questions

A single-storey rear extension may qualify for permitted development up to 4 metres for a detached house or 3 metres for other houses, subject to all the rules. Larger home extensions may extend up to 8 metres or 6 metres respectively through the prior approval process. These are the limits described in our permitted development guide, not automatic permission for any property. Check Dacorum Borough Council's guidance and the property's planning history.

Conservation areas and Article 4 Directions can remove some permitted development rights. Check Dacorum's conservation-area and listed-building records before relying on permitted development. The proposal must meet national limits as well as any conditions or restrictions attached to the property. A lawful development certificate can provide evidence that qualifying works are lawful. Listed-building consent and other approvals may still be needed.

Our fixed-fee design packages are Pre-Build from £1,950 + VAT, Premium £2,950 + VAT and Premium Plus £3,950 + VAT. Building work and statutory fees are separate. Use the free feasibility study for an indicative project-specific cost check.

Building regulation drawings are prepared for Building Notice submission. The Pre-Build and Premium packages do not include that submission; Premium Plus does, with the council fee excluded. Building Control determines compliance. Structural calculations are prepared by an independent qualified structural engineer.

Coverage: Within approximately 2 km of the town centre. Extensions, loft conversions, dormers, garage conversions and porches only.
